OPINION
STEWART, Judge.
In 2004, the Alaska legislature made two significant changes to AS 28.35.030, the law prohibiting driving while under the influence. Before that time, to convict a motorist of driving while under the influence based solely on the result of a chemical test of the motorist's breath or blood, the jury had to find that the motorist's blood alcohol level was at or above the legal limit at the time of driving.[1] The legislature in 2004 redefined the offense so that the defendant's blood alcohol level at the time of driving is no longer determinativenow, to find a motorist guilty of that offense, the jury need only find that a chemical test properly administered within four hours of driving showed a blood alcohol level at or above the legal limit at the time of the test.
Second, the legislature prohibited defendants in all prosecutions for driving while under the influence from offering evidence to show that they were less intoxicated at the time of driving than at the time of a later chemical test. (The legislature made one exception to this prohibition: the defendant may offer evidence to show that he consumed alcohol between the time of driving and the time of the chemical test.) That is, the legislature barred defendants from offering expert testimony or other evidence to show that the alcohol they had consumed before driving had not been fully absorbed into their bloodstream at the time of driving because, for instance, they ate a large meal right before drinking, or consumed the alcohol in "big gulps" shortly before they got in their car.
Douglas L. Valentine was convicted under this new law. He argues that his conviction should be overturned because the 2004 changes to the driving while under the influence law violate due process and equal protection, are vague and overbroad, create impermissible presumptions, violate the constitutional right to an independent test, and violate the supreme court's rule-making power. Having reviewed the record in Valentine's case and the legislative history of the 2004 amendments, we conclude that the statute survives all of Valentine's constitutional challenges.
Facts and proceedings
On June 18, 2005, at about 8:45 p.m., Fairbanks Police Sergeant Dan Welborn stopped Valentine for speeding. When he contacted Valentine, he noticed that he had a moderate odor of alcohol and that his eyes were watery and bloodshot. He administered three field sobriety tests, which Valentine failed, and then arrested him. At the station, Valentine submitted to a breath test, which showed a blood alcohol level of .099 percent. Valentine requested an independent test, which he obtained at 9:45 p.m. That blood test showed a blood alcohol level of .119 percent. The State charged Valentine under both theories *336 in AS 28.35.030: it alleged that Valentine was "under the influence" at the time of driving under subsection (a)(1), and that a chemical test showed that his "blood alcohol" level was above the legal limit under subsection (a)(2).
Before trial, Valentine filed a motion to dismiss, challenging the constitutionality of the 2004 amendments to AS 28.35. District Court Judge Winston S. Burbank denied the motion to dismiss. In his decision, Judge Burbank incorporated by reference an earlier ruling by District Court Judge Raymond M. Funk rejecting the same constitutional claims in a consolidated Fairbanks case, State v. Baxley, Marshall & Tyler.[2] The effect of the district court's ruling was to prohibit Valentine from offering evidence to show that, even though his blood alcohol level was above the legal limit at the time of his two chemical tests, he was not guilty of driving while under the influence under either theory because, at the time he drove, the alcohol he had consumed had not yet been fully absorbed into his bloodstream.
Valentine's case then proceeded to trial before Judge Donald D. Hopwood. At trial, Valentine argued that he had only consumed two beers, that people absorb alcohol at different rates, that there was ample evidence that he was not impaired at the time he performed the field sobriety tests, and that the State had no evidence of his actual blood alcohol level at the time of driving.
The jury convicted Valentine in a general verdict (that is, a verdict that did not specify whether he was convicted under subsection (a)(1) or (a)(2)). Valentine now appeals the denial of his motion to dismiss. He supplemented the record on appeal with the expert testimony presented in Judge Funk's consolidated case, State v. Baxley.
Background on the 2004 amendments to AS 28.35
In Conrad v. State,[3] this court addressed the question of whether the pre-2004 version of AS 28.35.030(a)(2) required the State to prove that the defendant's blood alcohol level met or exceeded the legal limit at the time of driving, or whether it was enough for the State to show that a chemical test properly administered within four hours of driving showed a blood alcohol level that met or exceeded the legal limit.[4]
Conrad submitted to a breath test about one hour and fifteen minutes after he was stopped by the police. That breath test showed a blood alcohol level of .154 percent.[5] Thirty minutes later, an independent blood test showed that Conrad's blood alcohol level was .131 percent.[6] At trial, Conrad presented what he called a "big gulp" defense: he claimed he had quickly consumed two beers right before he drove and that the alcohol from these beers had not been fully absorbed into his bloodstream at the time he was stopped.[7] Therefore, he argued, he was below the legal limit at the time he was driving even though a breath test more than one hour later showed a blood alcohol level above the legal limit.[8]
Although Conrad was able to argue his defense to the jury, the trial judge in effect instructed the jury that his defense was no defensethe judge told the jury that, under the version of AS 28.35.030(a)(2) in effect at that time, Conrad's guilt hinged on the result of his breath test, not on his alcohol level at the time he was driving. The jury convicted Conrad.[9]
On appeal, Conrad argued that the court's instruction was error. We agreed, ruling that "a defendant's guilt under [former] AS 28.35.030(a)(2) hinges on the defendant's blood alcohol content at the time the defendant operated or controlled a motor vehicle."[10] We observed that a number of states *337 had defined the offense in terms of the defendant's test resultand we suggested that the Alaska legislature might have the authority to do so as well.[11] But we concluded that the wording and legislative history of former AS 28.35.030(a)(2) "yield no such expression of legislative intent."[12]
We elaborated on this ruling when we denied the State's petition for rehearing.[13] The statute at issue in Conrad provided that a person committed the offense of driving while intoxicated if the person operated or controlled a motor vehicle "when, as determined by a chemical test taken within four hours after the alleged offense was committed, there [was] 0.08 percent or more by weight of alcohol in the person's blood."[14] We found the statute's use of "when" ambiguous, and we resolved that ambiguity against the State:
The problem here is the ambiguous reference of the adverb "when". Does the statute mean that a person is guilty if they operate or control a motor vehicle "when . . . [their blood contains] 0.08 percent or more . . . alcohol [by weight]"? Or does the statute mean that a person is guilty if they operate or control a motor vehicle "[and later], as determined by a chemical test taken within four hours [of] the alleged offense . . ., [their blood contains] 0.08 percent or more . . . alcohol [by weight]"?[15]
Several years later, in 2004, the legislature responded to the Conrad decision by amending AS 28.35.030. First, the legislature eliminated the adverb "when" from AS 28.35.030(a) to resolve the ambiguity identified in Conrad:
(a) A person commits the crime of driving while under the influence of an alcoholic beverage, inhalant, or controlled substance if the person operates or drives a motor vehicle or operates an aircraft or a watercraft
(1) while under the influence of an alcoholic beverage, intoxicating liquor, inhalant, or any controlled substance, singly or in combination; or
(2) and if [WHEN], as determined by a chemical test taken within four hours after the alleged operating or driving [OFFENSE WAS COMMITTED], there is 0.08 percent or more by weight of alcohol in the person's blood or 80 milligrams or more of alcohol per 100 milliliters of blood, or if [WHEN] there is 0.08 grams or more of alcohol per 210 liters of the person's breath[.][16]
Under the amended statute, a person commits the offense of driving while under the influence if (1) the person operates or drives a motor vehicle while under the influence or if (2) the person operates or drives a motor vehicle and "if, as determined by a chemical test taken within four hours after the alleged operating or driving, there is 0.08 percent or more by weight of alcohol in the person's blood or 80 milligrams or more of alcohol per 100 milliliters of blood, or if there is 0.08 grams or more of alcohol per 210 liters of the person's breath."[17] Thus, under the plain language of the amended statute, the defendant's guilt under subsection (a)(2) now hinges on the chemical test result, not on the defendant's blood alcohol level at the time of driving. (Guilt under subsection (a)(1) still hinges on the motorist's impairment at the time of driving.) During House Judiciary Committee discussion of this amendment, representatives of the Department of Law emphasized that the amendment was designed to remove the ambiguity in the statute that we identified in Conrad.[18]
*338 At the same time, the legislature added a new subsection, AS 28.35.030(s), which prohibited defendants from raising a "big gulp" or other "delayed absorption" defense to a charge of driving while under the influence under subsection (a)(1) or subsection (a)(2):
(s) In a prosecution under (a) of this section, a person may introduce evidence on the amount of alcohol consumed before or after operating or driving the motor vehicle, aircraft, or watercraft to rebut or explain the results of a chemical test, but the consumption of alcohol before operating or driving may not be used as a defense that the chemical test did not measure the blood alcohol at the time of the operating or driving. Consumption of alcohol after operating or driving the motor vehicle, aircraft, or watercraft may be used to raise such a defense.[19]
Deputy Attorney General Susan Parkes explained that this amendment was designed to eliminate the "big gulp" defense in driving while under the influence prosecutions:
[The amendment] addresses the "big gulp defense"[.] The current law says if a person is given [a breath] test within four hours of driving and [the result] is .08 [percent blood alcohol] or above, that person is legally intoxicated. However, the courts have allowed people to argue that they took a "big gulp" right before driving and although the [chemical test] was accurate at the time taken, the person's blood alcohol level was lower than that [at the time of driving]. [The Department of Law] does not believe the intent of the legislation was to get into the middle of a battle of experts, so [the amendment] would do away with that defense and overturn a case called Conrad, issued by the Court of Appeals.[20]
Subsection (s) was amended several times before the legislature arrived at the final language. Language was added to clarify that defendants may introduce evidence that they drank after driving.[21] Language was also added to clarify that defendants may introduce evidence of how much alcohol they consumed before driving to rebut or explain the results of the chemical testfor instance, a defendant may offer evidence that he only had two drinks before driving, and that the chemical test therefore must have been inaccuratebut not to argue that the alcohol he consumed before driving had not been fully absorbed into his bloodstream at the time of driving.[22]
During House Judiciary Committee discussion of the House version of the bill, Representative Max Gruenberg questioned whether judges, rather than legislators, should be deciding what evidence is relevant in a driving while under the influence prosecution. Representative Les Gara interjected that the committee was "changing the substance of the crime. . . . This isn't really a relevance issue; we're changing policy here." Representative Gruenberg then noted that the bill would make it a crime to have a blood alcohol level above the legal limit "even though a person might potentially have not been behind the wheel at that moment in time." Representatives Gara and Ralph Samuels agreed with that assessment, and Samuels added: "If it's in your stomach, it's as good as being in your blood, is what we're saying."[23] Susan Parkes of the Department of Law echoed: "[W]hat's being prohibited is *339 people [who have an illegal] level of alcohol in their bodies getting into a car and driving."[24]
Finally, the legislature amended AS 28.35.033(c) to add the following underlined language:
Except as provided in AS 28.35.030(s), the provisions of (a) of this section [providing, inter alia, that a .08 percent blood alcohol level gives rise to a presumption that a person is "under the influence"] may not be construed to limit the introduction of any other competent evidence bearing upon the question of whether the person was or was not under the influence of intoxicating liquor.[25]
The effect of this amendment to AS 28.35.033(c) was to prohibit defendants from offering "big gulp" or other "delayed absorption" evidence to rebut a chemical test result that is offered to show that the defendant was "under the influence" at the time of driving under AS 28.35.030(a)(1).
This legislative history, and the plain language of the amended statutes, indicate that the legislature intended to accomplish two things through this legislation. First, it intended to hinge a defendant's guilt in a driving while under the influence prosecution under subsection (a)(2) on the result of a chemical test properly administered within four hours of driving (if the test result is attributable to alcohol ingested before or during the operation of a motor vehicle). And, second, it intended to eliminate a "delayed absorption" defense to any prosecution under subsection (a)(1) or (a)(2) that relies in whole or in part on the result of a chemical test, so that defendants may not argue based on alcohol absorption rates that the result of their chemical test did not reflect their actual alcohol level at the time of driving.
The amended statutes are not void for vagueness
Valentine argues that the amended version of the driving while under the influence law is void for vagueness because guilt hinges on the result of a chemical test administered within four hours of driving, rather than on a motorist's blood alcohol level at the time of driving.
When no First Amendment rights are at stake, we consider two factors in determining if a statute is unconstitutionally vague. The first is whether the statute gives adequate notice to the ordinary citizen of what conduct is prohibited.[26] A statute may not be "so vague that men of common intelligence must necessarily guess at its meaning and differ as to its application."[27] The second consideration is whether the statute invites arbitrary enforcement because it gives too much discretion to prosecuting authorities.[28] To establish this second factor, the defendant must show a history or strong likelihood of uneven application.[29]
Valentine argues that the statute is impermissibly vague because it is difficult for a motorist to predict if, or when, within a four-hour period his alcohol level will reach or exceed the legal limit. He claims that the only way to prevent a driving while under the influence statute from being impermissibly vague is to rest guilt on the motorist's impairment at the time of driving.
To support this claim, Valentine cites the Pennsylvania Supreme Court's decision in Commonwealth v. Barud.[30] The statute at issue in that case barred operating a motor vehicle "if the amount of alcohol by weight in the blood of the person is 0.10% or greater at the time of a chemical test of a sample . . . obtained within three hours after the person drove, operated, or was in actual physical control of the vehicle."[31] The Pennsylvania *340 court struck down the statute, concluding that it did not provide a reasonable standard to guide conduct because it was too difficult for a motorist to predict when, or if, he would reach a .10 percent blood alcohol level within a three-hour period.[32]
At the outset, we note that Valentine's claim is not really a vagueness challenge. Valentine is not arguing that the language of the statute is unconstitutionally imprecise nor could he persuasively, since the statute unambiguously prohibits a blood alcohol level of .08 percent or more as measured by a chemical test properly administered within four hours of driving. Valentine's real claim is that the statute violates due process because it is too difficult for a motorist who chooses to drink alcohol before driving to gauge if, or precisely when, his conduct will violate the statute.
Regardless of how Valentine's argument is characterized, other courts that have addressed this issue (with the exception of the Pennsylvania Supreme Court in Barud) have rejected this claim.[33] As one court explained in upholding a statute that made it illegal to have a blood alcohol level of .10 percent as determined by a chemical test taken within two hours of driving:
While it certainly must be hard to predict if one's BAC has reached or will reach 0.10 percent within any time frame, this does not mean that the two-hour rule provides no notice of the prohibited conduct. To the contrary, the two-hour rule, just as the former time-of-driving rule, gives fair notice that, although driving after drinking is not illegal per se, driving becomes illegal after a certain level of consumption; the fact that people cannot sense exactly what their BAC is at any given moment or will be in two hours does not change this. As the Arizona State Supreme Court put it, "[w]here a statute gives fair notice of what is to be avoided or punished, it should not be declared void for vagueness simply because it may be difficult for the public to determine how far they can go before they are in actual violation."[34]
The Georgia Supreme Court similarly held that regardless of whether a statute forbids a certain blood alcohol level at the time of driving or within three hours of driving, "a person who drinks a substantial amount of alcohol . . . is put on notice that he chooses to drive at his own peril."[35]
Valentine argues that Alaska's statute is especially vague because the police have four hours from the time of drivingrather than the more typical two or three hours in states such as Pennsylvania and Georgiain which to obtain a chemical test. Valentine has no standing to challenge the statute on this ground because, as he concedes, his breath and blood tests were administered within one hour of driving.[36] But in any event, according to the expert testimony advanced by Valentine, most people reach their peak alcohol level within one hour after they stop drinking. Consequently, the fact that the police have four, instead of two or three, hours in which to obtain a sample would not make it appreciably more difficult for the typical motorist to evaluate whether they had consumed too much alcohol to legally drive.
We find the view adopted by the majority of courts persuasive and conclude that the amended driving while under the influence statutes give adequate notice of what conduct is prohibited. Valentine has not argued, much less shown, that there is a history or strong likelihood that the law will be unevenly applied. We therefore find no merit to his claim that the statute is impermissibly vague, and therefore violates due process.
*341 The amended statutes are not unconstitutionally overbroad
Valentine next argues that the amended driving while under the influence law is overbroad because it punishes people for innocent conduct. He argues that the law unconstitutionally criminalizes lawful conduct because a motorist can be convicted of driving while under the influence even if his blood alcohol level is below the legal limit at the time of driving.
This claim fails because, under the revised statutes, driving with a blood alcohol level below the statutory limit is not necessarily lawful conduct. As discussed earlier, the plain language and legislative history of the amended statutes indicate that it is now illegal to drive or operate a motor vehicle after ingesting enough alcohol to register a blood alcohol level of .08 percent or more at the time of a chemical test administered within four hours of driving. As Representative Samuels explained: "If it's in your stomach, it's as good as being in your blood."[37] Or, as Representative Gara declared:
We know that you're not a technician and that you didn't time the amount you had to drink to get you home before you got drunkyou essentially just got lucky that you hadn't exceeded .08 at the time you got in your car, but you had been drinking irresponsibly. And I think even though you're not technically at a .08 percent [at the time of driving], we want to punish you for having that much to drink and getting in your car, because I think the truth is, even at .05 and .06, you're putting the public in danger.[[38]]
To the extent that Valentine is arguing that the legislature has no authority to penalize a motorist whose blood alcohol level is lower than .08 percent at the time of driving, that claim is meritless. The legislature violates substantive due process by enacting a law that has "no reasonable relationship to a legitimate government purpose."[39] The State has a legitimate interest in preventing driving while under the influence[40] and it is the legislature's role, within constitutional limits, to determine the precise blood alcohol level or degree of impairment that makes operating a car unacceptably dangerous to the public. Valentine has not argued that the legislature's judgment is wrong, and that a motorist who drives or operates a motor vehicle after ingesting enough alcohol to register a blood alcohol level of .08 percent within the next four hours poses no risk to others. Indeed, the legislature previously recognized, in enacting AS 28.33.030(a)(2), the statute prohibiting operating a commercial motor vehicle with a blood alcohol level of .04 percent or more, that driving with a blood alcohol level of less than .08 percent might pose an unacceptable risk.
For these reasons, we reject Valentine's claim that the amended statutes are unconstitutionally overbroad because a defendant may be convicted of driving while under the influence even if his alcohol level at the time of driving is below the statutory limit.
The amended statutes do not impose criminal liability without mens rea
Valentine argues that the amended law unconstitutionally allows a person to be convicted without any proof of mens rea with respect to the circumstance of driving while impaired or with a blood alcohol level above the legal limit.
Valentine acknowledges that this court has repeatedly held that the offense of driving while under the influence does not require proof that the defendant was aware that he was legally impaired or that his blood alcohol level was above the legal limitit is enough that the defendant knowingly drank and knowingly drove.[41] As this court explained *342 in Morgan v. Anchorage[42]:
It certainly does not make sense to allow a defendant to claim that his intentional consumption of alcohol impaired his ability to know that he was intoxicated. It does make sense to require a person who drinks and drives to be responsible for not drinking to the point where he is under the influence of alcohol. He should drive at his peril rather than only at the public's peril.[[43]]
Valentine argues that this line of cases is at odds with our other decisions requiring a mens rea of at least criminal negligence with respect to the circumstance of driving with a revoked or suspended license.[44] But as we explain below, these cases are not irreconcilable; they simply reflect the different proof requirements and policy interests underlying prosecutions for driving with a suspended or revoked license and driving while under the influence.
To convict a defendant of driving with a suspended or revoked license, the State does not have to show that the defendant was aware that his license was suspended or revoked; nor does the State have to show that the defendant understood the legal effect or scope of that revocation or suspension.[45] All the State must prove with respect to that circumstance is criminal negligence: that a reasonable person in the defendant's position would have been aware of a substantial and unjustifiable risk that his license was revoked or suspended, and that the defendant's failure to perceive that risk constituted a gross deviation from the standard of care that a reasonable person would exercise.[46]
To convict a defendant of driving while under the influence, the State is not required to prove any mens rea with respect to the circumstance of having consumed too much alcohol to legally drive. But the State must prove that the defendant was legally intoxicated (either because his blood alcohol level met or exceeded the statutory limit within four hours of driving, or because he was under the influence at the time of driving) and that he knowingly drank and drove;[47] it is implicit in the proof of these elements that the defendant was criminally negligent as to the circumstance of being too impaired to legally drive. The conduct of consuming alcohol puts a person on notice that he may be impaired. Morgan and its progeny simply preclude a defendant from arguing that he did not have the required mens rea to commit the offense because, even though he knowingly drank and drove, he was too intoxicated to know he was impaired.
Valentine also argues that the line of cases following Morgan was implicitly overruled by the Alaska Supreme Court in State v. Hazelwood.[48] In Hazelwood, the supreme court explained that, when a criminal statute proscribes conduct only when a relevant circumstance *343 is present, a conviction under that statute must be predicated on a finding that the defendant was at least negligent with respect to that circumstance.[49] For instance, a defendant cannot be convicted of transporting illegally taken game unless the defendant was at least negligent with respect to the fact that the game was illegally takenbecause if the game was not illegally taken, transporting it would not be a crime.[50] Valentine argues by analogy that a person cannot be convicted of driving while under the influence unless the person was at least negligent with respect to the circumstance of being legally intoxicatedbecause drinking and driving is otherwise not sanctionable. This claim fails for the same reason discussed above: proof that the defendant was legally intoxicated and that the defendant knowingly consumed alcohol and drove is sufficient to establish that the defendant was negligent with respect to the circumstance that he was too impaired to legally drive. We therefore reject Valentine's claim that the amended law is unconstitutional because it imposes criminal liability without proof of mens rea.
The amended statutes did not deny Valentine due process by creating impermissible presumptions
Valentine argues that the amended law creates an impermissible presumption that a motorist was at least as intoxicated at the time of driving as at the time of a chemical test administered within four hours of driving.
We have previously identified two possible defects in a presumption directed against the accused in a criminal case: "(1) the nexus between the fact proved and the fact to be presumed may be so insubstantial as to violate due process[;] and (2) the presumption may undermine the government's duty to prove guilt beyond a reasonable doubt."[51]
Valentine attacks the amended driving while under the influence statutes on both these grounds. First, he argues that the presumption that a motorist was at least as intoxicated at the time of driving as at the time of a later chemical test is unconstitutional even if it is permissive and rebuttable because it has no basis in science. He argues that it is more likely, given alcohol elimination and absorption rates, that a motorist will be less intoxicated at the time of driving than at the time of a later chemical test. In advancing this claim, Valentine relies on expert testimony from State v. Baxley and the general rule that even a permissive presumption must be based on empirically valid inferences.[52]
Second, Valentine argues that this presumption is unconstitutional because the defendant can no longer rebut it by offering "delayed absorption" evidence. He argues that, because the defendant cannot offer this rebuttal evidence, the presumption verges on a mandatory conclusive presumptionthat is, a presumption that removes from the jury the element that the defendant was under the influence at the time of driving once the State proves that the defendant's chemical test result was at least .08 percent blood alcohol. He argues that this presumption violates Evidence Rule 303 by impermissibly shifting the burden of production (and perhaps the burden of persuasion) to the defendant.
As to Valentine's first claim, he has not shown that the presumption that a motorist was at least as intoxicated at the time of driving as at the time of a later chemical test lacks an empirical basis. Valentine advances expert testimony to show that it normally takes forty-five minutes to one hour for *344 alcohol to be fully absorbed after a person stops drinking, and that it could take as long as four hours for someone who ate a large meal or had an upset stomach. That means some people will have a lower alcohol level at the time of driving than at the time of a later chemical test. But that is not enough to invalidate the presumption. We owe considerable deference to the legislative facts underlying a presumption.[53] The inference that a person's alcohol level at the time of driving was at least as high as at the time of a later chemical test doubtless takes into account many factors beyond alcohol absorption ratesincluding the fact that many people who drink enough alcohol to become legally intoxicated do so over a period of time, not all at once right before driving a car.
Valentine's other claims must be addressed separately for prosecutions under subsections (a)(1) (the "under the influence" theory) and (a)(2) (the "blood alcohol" theory). With respect to prosecutions under subsection (a)(2), Valentine's claims fail for the reasons already discussed: the amended law does not create a presumption that the motorist was at least as intoxicated at the time of driving as at the time of the later chemical test. Under subsection (a)(2), it does not matter how intoxicated the motorist was at the time of driving. What matters is whether the motorist ingested enough alcohol before or while driving to have a blood alcohol level at or above .08 percent at the time of a chemical test administered within four hours of driving. The defendant may attack the accuracy of the chemical test, or show that alcohol was consumed after driving. What he cannot offer is evidence to show that the test did not measure his blood alcohol level at the time of driving because the alcohol he consumed before or while driving had not been fully absorbedevidence that is no longer relevant under the amended statutes.
Under AS 28.35.030(a)(1), guilt still hinges on whether the motorist is "under the influence" at the time of driving.[54] If the State charges the defendant under this subsection, and offers no evidence of a chemical test result, the defendant is still permitted to offer evidence to show that he was not under the influence at the time of driving. That is because subsection (s) only prohibits "delayed absorption" evidence that is offered to show "that the chemical test did not measure the blood alcohol at the time of operating or driving."[55] Thus, for instance, if the State presented testimony that the defendant must have been under the influence because he drank six beers before driving, the defendant could offer testimony to show that he drank those beers immediately before driving and that the alcohol had not been sufficiently absorbed into his blood to impair his driving.
But if the defendant is charged under subsection (a)(1) and the State offers a chemical test result as evidence that the defendant was under the influence at the time of driving, the defendant may not offer "delayed absorption" evidence to argue that the chemical test result did not accurately reflect his impairment at the time of driving.
To understand the significance of this, one must look to AS 28.35.033(a), a related statute which the legislature left unchanged in 2004. That statute outlines certain inferences juries may draw from a defendant's chemical test result in deciding if the defendant was under the influence at the time of driving.[56] Under the statute, the jury may infer from a chemical test result that shows a blood alcohol level of .04 percent or less that the defendant was not under the influence at the time of driving. If a test shows that the defendant's blood alcohol level *345 was more than .04 percent but less than .08 percent, there is no presumption, but the jury may consider the chemical test result, together with other competent evidence, to determine if the defendant was under the influence at the time of driving. If a test shows that the defendant's alcohol level was .08 or more, the jury may infer from this fact alone that the defendant was under the influence of alcohol. We have previously explained that these presumptions apply to the defendant's impairment at the time of driving.[57]
Consistent with this statute, the jurors in Valentine's case received the standard instructions informing them (1) that they "may" infer that he was under the influence if a chemical test showed that his blood alcohol level was at least .08 percent and (2) that they "may" infer that his chemical test result accurately reflected his alcohol level at the time of driving. We have previously upheld similar jury instructions based on the presumptions in AS 28.35.033(a) against claims that they impermissibly shifted the burden of proof to the defendant.[58]
Valentine's jury was further instructed that it could consider "any . . . competent evidence" to determine if Valentine was under the influence at the time of driving. To underscore this point, Valentine in closing argument detailed all the evidence he claimed showed he was not impaired at the time of driving, and reminded the jury that it was free to disregard any inference based on his chemical test results that he was under the influence when he drove.
As the record in Valentine's case demonstrates, there is no merit to the claim that the amended statutes create a mandatory conclusive presumption that directs the jury to find that the defendant was under the influence at the time of driving based on a chemical test result showing a blood alcohol level of at least .08 percent.[59] Rather, as was true before the 2004 revisions to the driving under the influence law, the jury may, but need not, infer from such a test result that the defendant was under the influence at the time of driving.[60]
It is true that, under the 2004 amendments, a defendant may no longer offer "big gulp" or other "delayed absorption" evidence to show that his chemical test result did not reflect his impairment at the time of driving.[61] But we conclude that the legislature had the authority to redefine the offense in this manner.[62] The legislature wished to discourage motorists from "playing a form of Russian roulette with the driving public" by consuming large amounts of alcohol and then racing the clock to reach their destination before the alcohol was absorbed into their bloodstream and they became too impaired to drive.[63] Prohibiting a "delayed absorption" defense was a reasonable way to deter this conduct. We cannot say there is no circumstance in which prohibiting this evidence would infringe the defendant's right to present a defense.[64] For instance, a court *346 would violate the defendant's due process rights if it allowed the State to offer evidence of alcohol elimination and absorption rates to show that the defendant was more intoxicated at the time of driving than at the time of a later chemical test, and then prohibited the defendant from countering the State's proof with a "delayed absorption" defense. But that is not the circumstance presented here. Legislative enactments are presumed to be constitutional, and Valentine has not met his burden to show a violation of due process in this case.[65]
The 2004 amendments do not infringe the rule-making power of the Alaska Supreme Court
Valentine also argues that the 2004 amendments unconstitutionally infringe the rule-making power of the Alaska Supreme Court. Specifically, he argues that the legislation conflicts with Alaska Evidence Rule 402 by preventing defendants charged with driving while under the influence from introducing evidence relevant to their alcohol level at the time of driving.
This claim is without merit. Evidence Rule 402 provides that "[a]ll relevant evidence is admissible, except as otherwise provided . . . by enactments of the Alaska Legislature[.]" Evidence Rule 402 thus expressly permits the legislature to define the parameters of relevant evidence, within constitutional limits. The language of AS 28.35.033(c) makes clear that the legislature intended to restrict the evidence that could be admitted in driving while under the influence prosecutions. There is thus no merit to Valentine's claim that the legislature infringed the supreme court's rule-making power.
The amended law does not violate the constitutional right to an independent test
Valentine next argues that the 2004 amendments violate a motorist's constitutional right to an independent test because the defendant can no longer use the result of his independent test to support his claim that his alcohol level was rising at the time of the test, and was probably lower at the time of driving.
In Snyder v. State,[66] the Alaska Supreme Court held that an accused has the right to an independent test for two reasons: (1) to give the defendant the opportunity to challenge the reliability of the State-administered breath test and, more broadly, (2) to safeguard the accused's right to obtain evanescent exculpatory evidence.[67] Under the amended statute, these rights are still protected.
Valentine argues that the amended statute violates due process by forcing the defendant into a "Hobson's choice" because any independent test that shows a blood alcohol level at or above .08 percent will necessarily be incriminating. But the right to an independent test has never guaranteed an exculpatory test result.
Valentine also asserts that the new statute rewards post-driving drinking by permitting a "big gulp" defense in that circumstance, thus encouraging motorists to keep a flask of alcohol in the car in case they are pulled over. It is unclear how this argument relates to Valentine's claim that the statute violates the right to an independent test. To the extent that Valentine is arguing that this claimed discrepancy violates due process, that argument fails. Alaska Statute 28.35.030(s) permits a defendant to offer evidence that he drank after driving to establish that the chemical test did not measure his alcohol level (or impairment) at the time of driving. It does not, as Valentine claims, preserve a "delayed absorption" defense for post-driving drinkers while barring that defense for pre-driving drinkers. Under the statute, evidence that the motorist drank after driving would not be admitted to show *347 that alcohol had not been fully absorbed into the bloodstream at the time of driving, but rather to show that the motorist's test result was above the legal limit due to alcohol that was consumed after driving. The legislature has a strong interest in discouraging motorists from consuming too much alcohol before driving a motor vehicle; it does not have this same interest in penalizing a motorist for drinking after driving. Allowing motorists to offer evidence of post-driving drinking is thus reasonably related to the statute's purpose.[68]
The amended statutes do not violate equal protection
Lastly, Valentine argues that the amended statutes violate Alaska's guarantee of equal protection of the laws. He argues that the statutes are overinclusive because they "criminaliz[e] those with rising blood-alcohol levels" and underinclusive because they "omit[ ] those with declining blood-alcohol levels." In other words, he argues that there is an insufficiently tight fit between the goal of the amended statutes and the means chosen to accomplish that goal because some motorists who had a blood alcohol level above the legal limit at the time of driving will escape responsibility for that offense while other motorists who were below the legal limit when driving will be convicted, based on the happenstance of when the state administers its chemical test.
The amended driving while under the influence law does treat similarly situated people differently, in that guilt in some cases may depend on the arbitrary timing of the chemical test. The question is whether the means-to-ends fit is imprecise enough to violate equal protection given the nature of the interest at stake.
In evaluating whether legislation violates the equal protection clause of the Alaska Constitution, this court applies a flexible test that is dependent on the importance of the rights involved:
Initially, [the court] must look to the purpose of the statute, viewing the legislation as a whole, and the circumstances surrounding it. It must be determined that this purpose is legitimate, that it falls within the police power of the state. Examining the means used to accomplish the legislative objectives and the reasons advanced therefore, the court must then determine whether the means chosen substantially further the goals of the enactment. Finally, the state interest in the chosen means must be balanced against the nature of the constitutional right involved.[[69]]
The State has a compelling interest in protecting the public from impaired drivers.[70] And although the right to drive is an important interest,[71] there is no constitutionally protected right to drink and drive.[72] Therefore, the law will survive an equal protection challenge if it substantially furthers the goals of the legislature.
The general purpose of the driving while under the influence law is to deter and penalize driving while under the influence.[73] Although arguably the most effective means of accomplishing that aim would be to convict only motorists whose alcohol level reaches a *348 certain level while driving, such precision is impossible given the technology now in use and the inevitable delays involved in administering a DataMaster or other chemical test.
Valentine has offered no evidence or argument to refute the legislature's judgment that a person who drives after consuming enough alcohol to register a .08 blood alcohol level within four hours is a danger to the public. And there is a rational basis for that judgment. A motorist cannot necessarily predict how long it will take him to drive to his destination or, given the many variables influencing how fast alcohol is absorbed, how impaired he will become en route. The 2004 amendments substantially further the legislature's goal of deterring a motorist who has consumed enough alcohol to reach a blood alcohol level of .08 percent or more within the four hours after driving or operating a motor vehicle. Given that the only interest at stake is the interest in drinking and driving, that is enough for the amended statute to survive constitutional scrutiny. While it is true that some who commit the offense will escape detection, and others will not, that is true of all criminal offenses.
Valentine also claims that the statute violates equal protection by hinging guilt for a pre-driving drinker on his alcohol level at the time of the chemical test while hinging guilt for a post-driving drinker on his alcohol level at the time of driving. But the statute does not treat similarly situated persons differently. All people charged with driving while under the influence may offer evidence to show that their alcohol level was above the legal limit at the time of a chemical test because of alcohol they consumed after driving. As discussed earlier, the legislature has little interest in penalizing motorists for drinking after driving.
For these reasons, we reject Valentine's equal protection challenge.
Conclusion
Valentine's conviction is AFFIRMED.
MANNHEIMER, Judge, dissenting in part.
AS 28.35.030 is the statute that defines the offense of driving under the influence and that specifies certain procedures and penalties pertaining to that offense. In 2004, in response to this Court's decision in Conrad v. State, the Alaska Legislature made two major changes to the DUI statute. For the reasons explained in this dissent, I conclude that one of the legislature's changes is constitutional, but the other is not.
Background of this case: this Court's construction of the DUI statute in Conrad
AS 28.35.030(a) defines two ways in which the operator of a motor vehicle can commit the offense of driving under the influence. Under subsection (a)(1), a motorist commits this crime by being "under the influence" of alcohol or controlled substances. Under subsection (a)(2), a motorist commits this crime by having a blood alcohol level of .08 percent or higher.
Subsection (a)(1), the "under the influence" clause, has always been interpreted to require proof that a motorist was under the influence of intoxicants at the time of driving (as opposed to being under the influence either before or after driving). However, there was a debate as to whether, under subsection (a)(2), a motorist could be convicted of DUI if their blood alcohol level was .08 percent or greater at the time they submitted to the chemical test, even though their blood alcohol level might have been lower at the time of driving.
We resolved this debate in Conrad v. State, 54 P.3d 313, on rehearing 60 P.3d 701 (Alaska App.2002). In Conrad, we held that subsection (a)(2) required proof that a motorist's blood alcohol level equaled or exceeded .08 percent at the time of driving. If a later chemical test of the motorist's breath or blood showed that the motorist had a blood alcohol level of .08 percent or more, this created a presumption that the motorist's blood alcohol level was at least that high at the time of drivingbut this presumption was rebuttable, and the motorist was entitled to introduce evidence tending to show that the result of the chemical test was not an accurate indicator of the motorist's blood alcohol level at the time of driving. Conrad, *349 54 P.3d at 315-16, on rehearing 60 P.3d at 702.
The legislature's response to Conrad: the 2004 amendments to the DUI statute
In 2004, the legislature responded to the Conrad decision by making two significant changes to the DUI statute.
First, the legislature rewrote subsection (a)(2), the subsection that defines the "blood alcohol level" theory of the crime. Conrad held that a person violated subsection (a)(2) if they operated a motor vehicle at a time when their blood alcohol level was .08 percent or higher. In response to Conrad, the legislature amended subsection (a)(2) so that, now, a person violates subsection (a)(2) if they operate a motor vehicle and if, within four hours of their operation of the vehicle, their blood alcohol level is .08 percent or higher, and if this blood alcohol level is attributable to the person's voluntary consumption of alcoholic beverages either before or during their operation of the vehicle.
(I agree with my colleagues that this amended version of subsection (a)(2) is constitutional, and I reach that conclusion for the reasons set forth in the majority opinion.)
Second, the legislature enacted a new subsection, AS 28.35.030(s), that prohibits defendants from raising a "delayed absorption" defense in a DUI prosecution.[1]
The "delayed absorption" defense is premised on the fact that there is an inevitable delay between a person's consumption of alcoholic beverages and their body's absorption of the alcohol into their bloodstream. This means that a person's blood alcohol level can continue to rise for some amount of time after they stop drinking. Because of this delay in the body's absorption of alcohol, there will be occasions when a chemical test administered to an arrested driver will yield a result that is significantly higher than the person's blood alcohol level at the time they were driving.
This phenomenon is illustrated by the facts of a case recently decided by this Court: Painter v. State, Alaska App. Memorandum Opinion No. 5192, 2007 WL 706752 (March 9, 2007).
When the defendant in Painter was initially stopped by the state troopers, he submitted to a preliminary breath test which showed his blood alcohol level to be .072 percent. (That is, the test showed that his blood alcohol level, according to the PBT, was under the legal limit.) One hour later, at the trooper station, Painter submitted to a second breath test, this time on a DataMaster; this second test showed his blood alcohol level to be .082 percent (i.e., slightly over the legal limit). Thirty-five minutes later, Painter obtained an independent blood test, and the result of this third test was .092 percent (i.e., considerably over the legal limit).
This potential discrepancy between a person's blood alcohol level at the time of testing and their blood alcohol level at the time they were driving is now irrelevant in prosecutions under subsection (a)(2) of the statute because subsection (a)(2) now declares that a person's guilt hinges on the test result, and not on the person's blood alcohol level at the time of driving.
But this potential discrepancy remains important in prosecutions under subsection (a)(1) of the statute. The legislature did not amend subsection (a)(1); this subsection still requires proof that a person operated a motor vehicle "while under the influence of an alcoholic beverage". Thus, to prove the offense of DUI under subsection (a)(1), the government must establish that the defendant operated or otherwise controlled a motor vehicle at a time when the defendant's ability to control the vehicle was impaired *350 due to the consumption of alcohol.[2] It is not sufficient to prove that the defendant operated a motor vehicle and then, sometime later, became impaired.
Because, under subsection (a)(1), the ultimate fact to be proved is the defendant's impairment, a defendant's guilt or innocence does not directly hinge on the result of the defendant's post-arrest chemical test. Theoretically, a person might have a blood alcohol level of .08 percent (or greater) and still not be impaired. Conversely, as we recognized in Ballard v. State, a person might be "under the influence" for purposes of subsection (a)(1)that is, the person might be demonstrably impairedeven though their blood alcohol level is less than the legal limit.[3]
Nevertheless, the result of the defendant's post-arrest chemical test can be an important element of the State's proof in prosecutions under subsection (a)(1). This is because of the evidentiary presumptions codified in a companion statute, AS 28.35.033(a).
In AS 28.35.033(a)(3), the legislature has decreed that when a person's post-arrest chemical test result is .08 percent blood alcohol or greater, this creates a rebuttable presumption that the person was "under the influence of an alcoholic beverage" for purposes of prosecutions under subsection (a)(1). In other words, in prosecutions under subsection (a)(1), if the defendant's post-arrest chemical test yielded a result of .08 percent or higher, a jury may lawfully find (based on this evidence alone) that the defendant was "under the influence" at the time that the defendant operated the motor vehicle.
(See Doyle v. State, 633 P.2d 306, 310-11 (Alaska App.1981), where we construed this statute to create a backward-looking presumption: a presumption that authorizes the jury to find, based on the result of a defendant's post-arrest chemical test, that the defendant was under the influence at the time of driving.)
The statute challenged in this appealAS 28.35.030(s)was enacted for the purpose of limiting the ways in which a defendant can rebut this statutory presumption of impairment. Specifically, this new subsection declares that a defendant is barred from introducing evidence of delayed absorption to rebut the presumption of impairment that arises under AS 28.35.033(a)(3) if the result of the defendant's post-arrest chemical test is .08 percent or higher.
Subsection (s) reads:
(s) In a prosecution [for driving under the influence], . . . [evidence of] the [defendant's] consumption of alcohol before operating or driving may not be used as a defense that the [defendant's] chemical test did not [reflect] the [defendant's] blood alcohol at the time of the operating or driving. [However, evidence of the defendant's] [c]onsumption of alcohol after operating or driving the motor vehicle, aircraft, or watercraft may be used to raise such a defense. [Emphasis added]
In other words, subsection (s) prohibits a defendant from introducing evidence that, because of the natural delay in the absorption of alcohol into the bloodstream, the defendant's blood alcohol level may have risen significantly between the time that the defendant stopped driving and the time that the defendant took the post-arrest chemical testand that, consequently, the defendant's post-arrest chemical test result might not be a trustworthy indicator of the defendant's level of intoxication at the time that the defendant was operating the motor vehicle.
Why I conclude that subsection (s) is unconstitutional when applied to prosecutions for DUI under subsection (a)(1)
In prosecutions under subsection (a)(1), the ultimate question is whether the defendant was "under the influence" at the time that they operated the motor vehicle. A defendant's post-arrest chemical test result does not directly prove or disprove this ultimate fact. However, because of the evidentiary presumption codified in AS 28.35.033(a)(3), the government can rest its case solely on the defendant's chemical test result. Pursuant to this statute, juries are *351 instructed that if a defendant's post-arrest chemical test result was .08 percent or higher, the jury can find that the defendant was impaired at the time of driving.
It is undisputed that there is a delay between a person's consumption of alcoholic beverages and the absorption of the alcohol into the person's bloodstream (where it causes intoxication). This delay in the absorption of alcohol into the bloodstream is obviously relevant to the issue of whether a defendant's post-arrest chemical test result is an accurate indicator of whether the defendant was impaired earlier, at the time of driving. Nevertheless, subsection (s) prevents defendants from offering evidence of delayed absorption to contest the statutory presumption of impairment that arises when a defendant's post-arrest chemical test result is .08 percent or higher.
This preclusion of evidence is irrelevant in prosecutions under subsection (a)(2)because, under the amended version of subsection (a)(2), the ultimate fact to be proved is now the defendant's blood alcohol level at the time of the chemical test, and not the defendant's earlier blood alcohol level at the time of driving. It therefore does not matter if the defendant's blood alcohol level might have been lower at the time of driving.
But in prosecutions under subsection (a)(1), the government must prove that the defendant was impaired at the time of driving. It is not enough to show that the defendant operated a motor vehicle and then became impaired later. Because of this, the rule of evidence preclusion codified in subsection (s) violates the guarantee of due process of law when it is applied to prosecutions under subsection (a)(1). It unjustifiably prevents defendants from introducing evidence that is both scientifically valid and directly relevant to the question of whether the defendant was impaired by alcohol at the time of driving.
As our supreme court stated in Smithart v. State, "a defendant's right to present a defense is a fundamental element of due process." 988 P.2d 583, 586 (Alaska 1999). See also Keith v. State, 612 P.2d 977, 982-83 (Alaska 1980).
Both Smithart and Keith involved evidentiary rulings by a trial judge that improperly restricted the defendant's presentation of a defense. However, the same principle applies when the evidentiary restriction is enacted by the legislature,[4] or is codified in a rule of court,[5] or is adopted as a rule of common law by a state's appellate courts.[6]
I acknowledge that the legislature has broad discretion when defining the elements of crimes, and that this broad discretion includes the authority to define elements in a manner that renders certain matters irrelevant (and thus inadmissible). For instance, in Abruska v. State, 705 P.2d 1261, 1265-66 (Alaska App.1985), and Neitzel v. State, 655 P.2d 325, 334-35 (Alaska App.1982), this Court upheld the legislature's authority to define the culpable mental states of "knowingly" and "recklessly" in such a way as to preclude a potential defense of voluntary intoxication.
See also Montana v. Egelhoff, 518 U.S. 37, 56, 116 S.Ct. 2013, 2023-24, 135 L.Ed.2d 361 (1996) (upholding a state legislature's authority to preclude evidence of a defendant's voluntary intoxication to rebut the government's proof of the defendant's culpable mental state); Fisher v. United States, 328 U.S. 463, 475-77, 66 S.Ct. 1318, 1324-25, 90 L.Ed. 1382 (1946) (upholding Congress's authority to preclude a defendant from introducing evidence of a mental disability or deficiency short of insanity on the issue of the defendant's capacity for premeditation and deliberation); Muench v. Israel, 715 F.2d 1124, 1144-45 (7th Cir.1983) (holding that the states "[are] not constitutionally compelled to recognize the doctrine of diminished capacity", and that therefore "a state may exclude expert testimony offered for the purpose of establishing that a criminal defendant lacked the capacity to form a specific intent."); People *352 v. Carpenter, 464 Mich. 223, 627 N.W.2d 276, 284-85 (2001) (same).
The Alaska Legislature pursued this course when it amended the "blood alcohol level" clause of the DUI statute, subsection (a)(2): the legislature amended the definition of the crime in a way that made it irrelevant whether the result of the defendant's post-arrest chemical test accurately reflected the defendant's blood alcohol level at the time of driving.
But the definition of DUI under subsection (a)(1) remains the same as it has always been: the government must prove that the defendant was under the influence at the time the defendant operated the motor vehicle.
Moreover, as we explained in Doyle, the evidentiary presumption codified in AS 28.35.033(a)(3) is a backward-looking presumption that relates to the defendant's physical and mental condition at the time of driving. Under this statute, a test result of .08 percent or higher does not give rise to a presumption that the defendant was under the influence at the time of the test; rather, it gives rise to a presumption that the defendant was under the influence at the time of driving.
Because the ultimate fact to be proved is the defendant's impairment at the time of driving, and because the scientifically recognized phenomenon of delayed absorption is directly relevant to the jury's assessment of whether the result of the defendant's post-arrest chemical test is a trustworthy indicator of the defendant's earlier impairment, the legislature may not prohibit the defendant from presenting evidence about delayed absorption, and may not prohibit the defendant from asking the jury to consider this phenomenon when the jury assesses whether the defendant was under the influence at the time of driving.
For these reasons, I conclude that the evidentiary prohibition codified in AS 28.35.030(s) violates a defendant's right to due process of law when the defendant is prosecuted for DUI under AS 28.35.030(a)(1) and the government relies on the result of a post-driving chemical test.
NOTES
[1] Under AS 28.35.030(a)(2), a motorist commits the crime of driving while under the influence if "as determined by a chemical test taken within four hours after the alleged operating or driving, there is 0.08 percent or more by weight of alcohol in the person's blood or 80 milligrams or more of alcohol per 100 milliliters of blood, or if there is 0.08 grams or more of alcohol per 210 liters of the person's breath." For convenience, we refer to this as the "blood alcohol" theory, though we recognize that the State may also establish guilt under subsection (a)(2) with evidence of the concentration of alcohol in the motorist's breath.

[1] In the 2004 legislative hearings, this defense was referred to as the "big gulp" defensea reference to the possibility that a motorist had hurriedly consumed a large quantity of an alcoholic beverage shortly before the police pulled the motorist over. Although the phrase "big gulp" may be catchier than "delayed absorption", this latter phrase is a more accurate description of the defense. There are several potential reasons why the absorption of alcohol into a person's bloodstream might be delayedfor example, illness or the recent consumption of a heavy meal. And it is this delay that is the crucial component of any defense claim that a post-arrest chemical test result might not accurately indicate the defendant's blood alcohol level at the time of driving.
