Defendant Lisa Deherrera appeals from a conviction for possession of methamphetamine, a third degree felony, in violation of Utah Code Ann. § 58 — 37—8(2)(a)(i) (Supp. 1998). Defendant argues the trial court erred by concluding the good faith exception to the exclusionary rule applied to admit evidence obtained in violation of the United States Constitution and a state statute during an administrative traffic checkpoint stop. We agree with defendant and conclude the good faith exception does not apply to the circumstances of this ease. We therefore reverse the trial court’s suppression ruling and remand for further proceedings.
BACKGROUND
On June 15, 1992, the Utah County Attorney’s Office submitted for approval to a Fourth Circuit Court judge a plan for conducting an administrative traffic checkpoint in Tibbie Fork Canyon. That same day, the judge issued findings noting the conformity of the plan to the statutory requirements of section 77-23-104 of the Utah Code and an order authorizing the plan. See Utah Code Ann. § 77-23-104 (Supp.1992) (outlining statutory requirements for administrative traffic checkpoint).
" Under the terms of the authorized plan, the traffic checkpoint was to run from 1:00 p.m. to 3:00 a.m. from June 15, 1992, to September 30, 1992. All traffic running east and west would be stopped. The officers conducting the stop would inspect license plates, registration certificates, insurance cards, and compliance with seatbelt and child restraint requirements. They also would ask drivers if the drivers had been drinking or were impaired by controlled substances. In addition, the plan authorized officers to “visibly inspect the operation of required lights and other required exterior safety devices” and to “inspect for other apparent criminal *502activity.” Ninety-six law enforcement officers, listed by name and position in the authorized plan, could participate in the traffic checkpoint.
On August 31, 1992, a Fourth Circuit Court judge authorized an amendment to the original Tibbie Fork Canyon administrative traffic checkpoint plan. The amendment allowed the traffic checkpoint to continue running from September 1, 1992, to November 30, 1992, and added eight officers from the Department of Wildlife Resources to the previous roster of ninety-six officers.1
Additional amendments expanded the Tib-bie Fork Canyon traffic checkpoint plan and authorized it to continue for almost four years.2 On December 2, 1992, another authorized amendment added seven Utah Highway Patrol officers to the checkpoint roster and allowed the checkpoint to continue running from December 1,1992, to February 28, 1993. On May 26, 1993, a third amendment added three United States Forest Service Law Enforcement officers to the roster and allowed the checkpoint to run from June 1, 1993, to August 31, 1993. On July 7,1994, a fourth amendment added seven new officers from various agencies to the roster and allowed the checkpoint to run from August 31, 1994, to August 31, 1995. The final amendment, authorized on May 26, 1995, again extended the checkpoint dates, allowing the checkpoint to run from May 26, 1995, to August 31, 1996. This final amendment also significantly increased the number of officers authorized to participate in the checkpoint. Rather than listing each officer by name, this final amendment simply allowed “[a]ll sworn and/or certified law enforcement officers” from the Utah County Sheriffs Office, the Utah Highway Patrol, the Utah Division of Wildlife Resources, the United States Forest Service, and the Utah State Parks and Recreation to participate in the checkpoint, stipulating only that the checkpoint supervisor be a sergeant, lieutenant, or captain of the Utah County Sheriffs Office.
On September 16,1995, around 6:35 p.m., a deputy from the Utah County Sheriffs Office stopped defendant at the Tibbie Fork Canyon traffic checkpoint. During the course of the stop, the deputy discovered that defendant did not have a valid driver’s license and that she was driving an unregistered ear. Because no one else in the car could legally drive the car, it was impounded.
Another deputy asked defendant to exit the car. Defendant appeared to the deputy to be very angry and upset. Because the Tibbie Fork Canyon area is remote and because the deputy realized defendant and her friends would be waiting unsupervised until a ride was available, the deputy asked defendant if she had any weapons. Defendant replied that she did not have a knife. Defendant’s answer made the deputy even more concerned for his safety, so he conducted a Terry frisk, see Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), which led to his discovery of methamphetamine on defendant’s person.
Defendant was charged with possession or use of methamphetamine (Count I), unlawful possession of drug paraphernalia, driving on a revoked driver’s license, driving without insurance, and driving with expired registration. Defendant pleaded not guilty to all charges and moved to suppress the evidence.
The trial court concluded that the Tibbie Fork Canyon administrative traffic checkpoint plan violated Utah law and the United States Constitution because it was overly broad. The court specifically stated three ways in which the plan violated Utah law and the Constitution. First, the duration of the traffic checkpoint was “entirely too long” and did not meet the intent of Utah law. See generally Utah Code Ann. § 77-23-104 (1995). Second, the plan violated the statute by not specifically including the names of the officers authorized to conduct the search. See id. § 77-23-104(2)(a)(v). Third, the plan’s purpose and the instructions given to the officers at the roadblock both went beyond the statute’s scope, see id. § 77-23-*503104(2), and violated the third criterion of the Sitz test. See Michigan Dep’t of State Police v. Sitz, 496 U.S. 444, 455, 110 S.Ct. 2481, 2488, 110 L.Ed.2d 412 (1990) (stating that third criterion of balancing test is “the degree of intrusion upon individual motorists who are briefly stopped”); see also Utah Code Ann. § 77-23-104(2)(b)(i), (ii). Regarding its last point, the trial court explained that roadblocks are ideally set up to check for drunk drivers, and “[b]y broadening the search the officers violate the third criterion of the Sitz test and the search conducted at the roadblock becomes too intrusive upon an individual’s rights.” Sitz, 496 U.S. at 455, 110 S.Ct. at 2488 (holding that administrative traffic checkpoint does not violate Fourth Amendment because' checkpoint’s narrow purpose is preventing drunken driving and system used to carry out checkpoint reasonably advances State’s interest to prevent drunken driving); see also id. at 455-56, 110 S.Ct. at 2488 (Blackmun, J., concurring) (stressing number of tragedies caused by drunken driving in United States).
Nevertheless, the trial court determined the evidence should not be suppressed because, it concluded, the good faith exception to the exclusionary rule applied to defendant’s stop. Therefore, the trial court denied defendant’s motion to suppress.
After the trial court denied her motion to suppress, defendant conditionally pleaded no contest to Count I, preserving for appeal the issues raised in her motion to suppress. See State v. Sery, 758 P.2d 935 (Utah Ct.App.1988). Defendant now appeals the trial court’s application of the good faith exception and the resulting denial of her motion to suppress.
ISSUE AND STANDARD OF REVIEW
The trial court determined that the administrative traffic checkpoint plan under which the officers who stopped defendant were operating violated Utah Code Ann. § 77-23-104 (1995) and the Fourth Amendment to the United States Constitution. On appeal, both the State and defendant agree with the trial court that the plan violated Utah law and the Constitution. We therefore need not review whether the plan violated Utah law or the Constitution. Instead, the only issue we address on appeal is whether the good faith exception to the exclusionary rule applies to this case. Specifically, we address whether the good faith exception applies to admit evidence obtained after making a warrantless administrative traffic checkpoint stop, which was conducted pursuant to a judicially approved administrative traffic checkpoint plan that violated both Utah law and the United States Constitution.3
Whether the good faith exception applies to an administrative traffic checkpoint stop under these circumstances is an issue of first impression in Utah. Resolution of this issue requires us to examine and interpret United States Supreme Court cases discussing the good faith exception to the exclusionary rule. Because appellate courts are in as good a position as trial courts to interpret case law, we consider the issue before us as presenting a question of law and therefore review the trial court’s decision for correctness. See State v. Richardson, 843 P.2d 517, 518 (Utah Ct.App.1992); cf. Stevensen v. Goodson, 924 P.2d 339, 346 (Utah 1996).
ANALYSIS
In Weeks v. United States, 232 U.S. 383, 34 S.Ct. 341, 58 L.Ed. 652 (1914), overruled in part by Mapp v. Ohio, 367 U.S. 643, 81 S.Ct. 1684, 6 L.Ed.2d 1081 (1961), overruled in part by Stone v. Powell, 428 U.S. 465, 96 S.Ct. 3037, 49 L.Ed.2d 1067 (1976), the United States Supreme Court held, for the first time, that ‘“in a federal prosecution the Fourth Amendment barred the use of evidence secured through an illegal search and seizure.’ ” Mapp, 367 U.S. at 648, 81 S.Ct. at 1688 (quoting Wolf v. Colorado, 338 U.S. 25, 28, 69 S.Ct. 1359, 1361, 93 L.Ed. 1782 (1949), *504overruled by Mapp). Forty-seven years later, in Mapp v. Ohio, the Supreme Court declared that the exclusionary rule also applied in state courts by holding “that all evidence obtained by searches and seizures in violation of the Constitution is, by that same authority, inadmissible in a state court.” Mapp, 367 U.S. at 655, 81 S.Ct. at 1691.
Twenty-three years after Mapp, in United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984), the United States Supreme Court established a good faith exception to the exclusionary rule. The good faith exception announced in Leon provides that the exclusionary rule does not bar the use in the prosecution’s case in chief of evidence obtained by officers acting in reasonable reliance on a search warrant issued by a detached and neutral magistrate but ultimately found to be unsupported by probable cause. See id. at 900, 913, 104 S.Ct. at 3409, 3415.
Three years after Leon, in Illinois v. Krull, 480 U.S. 340, 107 S.Ct. 1160, 94 L.Ed.2d 364 (1987), the Supreme Court announced another exception to the exclusionary rule “similar” to that announced in Leon. Id. at 342, 107 S.Ct. at 1163. In Krull, the Court announced that a good faith exception to the exclusionary rule applied “when an officer’s reliance on the constitutionality of a statute is objectively reasonable, but the statute is subsequently declared unconstitutional.” Id. at 346, 353, 107 S.Ct. at 1165, 1168-69.
The State, relying on Leon and Krull, asserts the trial court correctly applied the good faith exception to the exclusionary rule in this case. However, we conclude that the case before us presents a situation different enough from Leon and Krull that the good faith exceptions announced in those cases do not apply to the case before us.
The good faith exception established in Leon applies to circumstances in which an officer applies for a warrant allegedly sup: ported by probable cause, the officer receives a judicially authorized warrant, the officer acts in objectively reasonable good faith on the warrant, and then a judge determines the warrant was not supported by probable cause. In this case, the officers relied on a judicial officer’s approval. However, the facts of this case otherwise significantly differ from those in a Leon exception situation. Here, the officers who stopped defendant did not conduct their seizure pursuant to a judicially issued warrant that was later found to be unsupported by probable cause. Rather, in this case the officers implementing the plan seized defendant and all other motorists passing through the traffic checkpoint pursuant to a judicially approved plan. In addition, no showing of probable cause, or even reasonable suspicion, was ever required of the officers seeking the approval of the administrative traffic checkpoint plan. The absence of any probable cause showing, mistaken or otherwise, is a significant difference.
The Court also limited the good faith exception to the exclusionary rule announced in Krull to situations different from that before us. The Krull good faith exception applies to the narrow situation where an officer acts in objectively reasonable good faith reliance on a statute that authorizes the officer to conduct warrantless searches, which statute is later determined to be unconstitutional. The case before us falls outside the Krull exception in three significant ways.
First, unlike in Krull, the officers in this case were not acting pursuant to a statute that was later declared unconstitutional. See Krull, 480 U.S. at 342-346, 107 S.Ct. at 1163-65. Instead, the officers in this case were acting pursuant to a judicially approved administrative traffic checkpoint plan. Second, it was the plan, not the statute, that was declared unconstitutional. The statutes authorizing administrative traffic checkpoint plans, see Utah Code Ann. §§ 77-23-103(5), - 104 (1995), have not been declared unconstitutional.
Third, in this case the trial court determined, and both parties agree, that the Tibbie Fork Canyon traffic checkpoint plan violated the state statute authorizing administrative traffic checkpoints. See id. However, in Krull, the Supreme Court specifically excluded from the scope of the good faith exception the situation where an officer acts in violation of the state statute au*505thorizing the search. See Krull, 480 U.S. at 360 n. 17, 107 S.Ct. at 1172-73 n. 17 (declining “to recognize an exception for an officer who erroneously, but in good faith, believes he is acting within the scope of a statute”). In other words, under Krull, even if an officer acts in good faith reliance on a statute, the Krull good faith exception would not apply if the officer acted outside the statute’s scope. See id. at 360 n. 17, 107 S.Ct. at 1172-73 n. 17. Indeed, the officers here were acting outside the scope of the statute.
Because the circumstances of this ease significantly differ from the circumstances in Leon and Krull, we hold that neither the Leon nor the Krull good faith exception applies to the case before us.4
We note, in recognition of the emphasis the Supreme Court placed on the deterrent purpose of the exclusionary rule in Leon and Krull, see Leon, 468 U.S. at 907 & n. 6, 916-21, 104 S.Ct. at 3412 & n. 6, 3417-19; Krull, 480 U.S. at 347 — 49, 107 S.Ct. at 1165-67, that allowing the exclusionary rule to exclude evidence obtained under the circumstances of the case before us does serve a deterrent function. The officers who actually conduct the administrative traffic checkpoint stops by stopping passing cars and briefly checking for specified violations may not be deterred by suppressing illegally obtained evidence because they are merely carrying out orders to conduct the approved stops. However, other involved officers should be deterred by the suppression of evidence obtained in a manner that violates the Constitution. At the very least, those involved with proposing the administrative traffic checkpoint plan and seeking judicial approval of it must be encouraged to conform their actions to both state statutes and the Constitution.
Moreover, we decry the mechanism by which the .Utah County Attorney’s Office sought to enlarge the application of the administrative traffic checkpoint statute. Instead of presenting the judicial officer from whom approval was sought with a new and coherent plan each time a change was sought, the county attorney simply presented amendments, all contained within the same short document, that referred to the original administrative traffic checkpoint plans. Each time the plan was presented, both the county attorney, as an officer of the court, and the judge approving the plan, as a judicial officer, had an obligation to examine the entire plan in terms of the statutory requirements. In addition, had the county attorney presented the plan and its amendments in terms of the statute, and had the judicial officer reviewed them as such, statutory violations may have been avoided. It is difficult to see how the plan would have been approved, at least in terms of its compliance with the statute, had such a procedure been followed. The statute clearly states requirements that were not followed in this case, such as the requirement that officers on the plan’s roster be listed by name. See Utah Code Ann. § 77-23-104(2)(a)(v).
Absent an exception to the exclusionary rule, Mapp requires us to exclude “all evidence obtained by searches and seizures in violation of the Constitution.” Mapp, 367 U.S. at 655, 81 S.Ct. at 1691. There is no dispute that the stop of defendant at the Tibbie Fork Canyon traffic checkpoint was unconstitutional. Nor is there any dispute that, absent the good faith exception, all evidence obtained subsequent to defendant’s stop should be suppressed as “fruit of the poisonous tree.” Wong Sun v. United States, 371 U.S. 471, 487-88, 83 S.Ct. 407, 417, 9 L.Ed.2d 441 (1963). The United States Supreme Court has reserved to itself the power to announce exceptions to the exclusionary rule. None of the good faith exceptions announced by the Court apply here. As a result, we have no alternative but to conclude that no good faith exception to the exclusionary rule applies to this case. We reverse the trial court’s suppression ruling and remand for further proceedings consistent with this opinion.
*506CONCLUSION
We hold that the trial court erred by concluding the good faith exception to the exclusionary rule applies to the case before us. We therefore hold that all evidence obtained as a result of defendant’s administrative traffic checkpoint stop must be suppressed pursuant to Mapp and Wong Sun.
Reversed and remanded.
BILLINGS, J., concurs.
. The August 1992 amendment simultaneously made the same amendments to eight other administrative traffic checkpoint plans.
. The same amendments were made to eight other administrative traffic checkpoint plans through the same documents authorizing the Tib-bie Fork Canyon plan amendments.
. Defendant urges us to address the constitutionality of Utah Code Ann. § 77-23-104, which outlines the requirements of an administrative traffic checkpoint. However, "Utah courts have consistently refused to reach the constitutionality of a statute when there are other independent grounds to resolve the case.” State v. Ramirez, 924 P.2d 366, 370 (Utah Ct.App.1996). In accordance with this principle, we decline to determine the constitutionality of section 77-23-104 because we decide this case on other grounds.
. We emphasize that we do not reach the issue of whether officers, when strictly complying with the administrative traffic checkpoint statute, may act in good faith if the statute is later ruled unconstitutional. See Krull, 480 U.S. at 355 n. 12, 107 S.Ct. at 1170-71 n. 12 (noting Court sees "no valid reason to distinguish between statutes that define substantive criminal offenses and statutes that authorize warrantless administrative searches”).
