NATURE OF CASE
Thanh Le was injured in a one-vehicle accident. The vehicle was driven by Thanh’s grandfather, Thomas Lautrup. Thanh’s parents, Huy Le and Melissa Le, filed a negligence action against Lautrup in the district court for Douglas County. In their petition, the Les challenged the constitutionality of Nebraska’s guest statute, Neb. Rev. Stat. § 25-21,237 (Reissue 1995), which limited Lautrup’s liability to damage caused by his gross negligence or intoxication. Intoxication was not an issue in this case.
The district court rejected the Les’ challenge to the constitutionality of § 25-21,237 and, in response to Lautrup’s demurrer, dismissed the Les’ theories of recovery based on simple negligence. The action went to trial on the sole remaining theory of gross negligence, and the jury found in Lautrup’s favor. The Les appeal. We conclude that the district court did not err in rejecting the Les’ challenge to the constitutionality of § 25-21,237, and we affirm.
STATEMENT OF FACTS
On June 20, 2001, Thanh Le, then 15 years old, was a passenger in the back seat of a vehicle driven by Lautrup. Lautrup and *933Thanh were returning to Omaha, Nebraska, from a family fishing and camping trip at Calamus Lake near Burwell, Nebraska. While driving on Highway 91 in Platte County, Nebraska, Lautrup’s vehicle drifted off the right side of the highway and the right wheels of the vehicle left the paved surface. Lautrup attempted to correct his course, but the right wheels hit the edge of the pavement, causing Lautrup to lose control of the vehicle and causing the vehicle to roll. Thanh was thrown from the vehicle and was injured. Police investigators determined that Lautrup had not been drinking, that he had not fallen asleep, and that he was not speeding prior to the accident, but that a momentary inattention on Lautrup’s part contributed to the accident. At the time of the accident, neither Thanh nor his parents lived with Lautrup nor were they financially supported by Lautrup.
The Les filed an action against Lautrup on February 21,2002. In an amended petition, the Les set forth three theories of recovery: (1) negligence in the operation of the vehicle, (2) gross negligence within the meaning of § 25-21,237, and (3) negligence in failing to ensure that Thanh was properly secured by a seat-belt. The Les alleged in their petition that Lautrup’s liability could be predicated on negligence without the need to prove gross negligence under § 25-21,237 because § 25-21,237 was unconstitutional to the extent it pertained to the grandparent-grandchild relationship.
Section 25-21,237, as amended in 1981, controls this case. Section 25-21,237 provides:
The owner or operator of a motor vehicle shall not be liable for any damages to any passenger or person related to such owner or operator as spouse or within the second degree of consanguinity or affinity who is riding in such motor vehicle as a guest or by invitation and not for hire, unless such damage is caused by (1) the driver of such motor vehicle being under the influence of intoxicating liquor or (2) the gross negligence of the owner or operator in the operation of such motor vehicle.
For the purpose of this section, the term guest is hereby defined as being a person who accepts a ride in any motor vehicle without giving compensation therefor but shall not be construed to apply to or include any such passenger in a *934motor vehicle being demonstrated to such passenger as a prospective purchaser. Relationship by consanguinity or affinity within the second degree shall include parents, grandparents, children, grandchildren, and brothers and sisters. Should the marriage of the driver or owner be terminated by death or dissolution, the [affinal] relationship with the blood kindred of his or her spouse shall be deemed to continue.
Lautrup demurred to the two theories of recovery based on simple negligence and argued that recovery on such basis was barred by § 25-21,237. The Les responded to the demurrer by arguing that § 25-21,237 was unconstitutional. The district court concluded that § 25-21,237 was constitutional and that it prevented recovery on the basis of simple negligence. The court therefore dismissed those theories of recovery based on simple negligence. The case proceeded to trial solely on the basis of gross negligence. The jury found in favor of Lautrup. The Les appeal.
ASSIGNMENTS OF ERROR
The Les assert that the district court erred in failing to find § 25-21,237 to be unconstitutional and in dismissing their theories of recovery based on simple negligence.
STANDARD OF REVIEW
Whether a statute is constitutional is a question of law; accordingly, the Nebraska Supreme Court is obligated to reach a conclusion independent of the decision reached by the court below. Ptak v. Swanson, ante p. 57, 709 N.W.2d 337 (2006).
ANALYSIS
The Les assert that § 25-21,237 is unconstitutional and that the district court erred when it concluded that their theories of recovery based on simple negligence must be dismissed and that they were required to prove gross negligence by Lautrup in order to succeed on their petition. We conclude that the Les have failed to establish that § 25-21,237 is unconstitutional and that therefore, the district court did not err when it concluded that § 25-21,237 was not unconstitutional and dismissed their theories of recovery based on simple negligence.
The guest statute, as amended in 1981 and found at § 25-21,237, controls this case. In Botsch v. Reisdorff, 193 Neb. *935165, 226 N.W.2d 121 (1975), this court rejected a constitutional challenge to an earlier version of the guest statute which was then codified at Neb. Rev. Stat. § 39-6,191 (Reissue 1974). Prior to the Legislature’s amendment of the guest statute in 1981, this court rejected various invitations to reconsider Botsch and to declare the guest statute unconstitutional. See, Cushing v. Bernhardt, 210 Neb. 272, 313 N.W.2d 688 (1981); Beebe v. Sorensen Sand & Gravel Co., 209 Neb. 559, 308 N.W.2d 829 (1981); Kreifels v. Wurtele, 206 Neb. 491, 293 N.W.2d 407 (1980); Circo v. Sisson, 193 Neb. 704, 229 N.W.2d 50 (1975); Lubash v. Langemeier, 193 Neb. 371, 227 N.W.2d 405 (1975).
The Legislature amended the guest statute in 1981. Prior to the amendment, the statute had pertained to all nonpaying guests; that is, nonpaying guests were precluded from bringing suit based on simple negligence. After the amendment, the guest statute pertained to only nonpaying guests who were related to the driver within the second degree of consanguinity which was defined to include parents and children, grandparents and grandchildren, and brothers and sisters. In 1998, this court rejected a constitutional challenge to the post-1981 version of the guest statute. Coburn v. Reiser, 254 Neb. 495, 577 N.W.2d 289 (1998).
The Les argue that Coburn is not controlling because the question of constitutionality was not fully explored and was not necessary to the disposition of that case. We recognize that Coburn, relying on pre-1981 authority, summarily concluded that the guest statute was not unconstitutional without discussion of the bases for the challenge in Coburn or the fact that the statute had been amended subsequent to the time that prior challenges had been rejected. We therefore believe it would be helpful to consider whether the current guest statute is constitutional in light of the arguments offered by the Les.
On appeal, the Les argue that the guest statute violates three provisions of the Nebraska Constitution: the due process and equal protection clauses of Neb. Const. art. I, § 3, and the special privileges and immunities clause of Neb. Const. art. Ill, § 18. Neb. Const. art. I, § 3, provides: “No person shall be deprived of life, liberty, or property, without due process of law, nor be denied equal protection of the laws.” Neb. Const. art. III, § 18, provides: “The Legislature shall not pass local or special laws ... *936[granting to any corporation, association, or individual any special or exclusive privileges, immunity, or franchise whatever.” We consider the constitutionality of § 25-21,237 under Neb. Const. art. I, § 3, and art. III, § 18.
Section 25-21,237 Does Not Violate Neb. Const. art. 1, § 3.
Although the Les assert that the statute violates both the due process and the equal protection clauses of the Nebraska Constitution, their arguments focus mainly on the equal protection aspects of Neb. Const. art. I, § 3, and we therefore focus our analysis on the equal protection clause. The party attacking a statute as violative of equal protection has the burden to prove that the classification violates the Equal Protection Clause. Waste Connections of Neb. v. City of Lincoln, 269 Neb. 855, 697 N.W.2d 256 (2005). We conclude that the Les have not proved that § 25-21,237 violates Nebraska’s equal protection clause.
The principle of equal protection guarantees that similar persons will be dealt with similarly by the state, but does not foreclose the state from classifying persons or from differentiating one class from another when enacting legislation. Waste Connections of Neb., supra. The equal protection guarantee simply keeps governmental decisionmakers from treating differently persons who are in all relevant aspects alike. Id. In an equal protection challenge, when a fundamental right or suspect classification is not involved, the act is a valid exercise of police power if the act is rationally related to a legitimate governmental purpose. Id.
Despite the Les’ argument that we should apply a higher standard of scrutiny, we determine that no fundamental right or suspect classification is involved here and that therefore, the rational basis test applies. Under the rational basis test, the Equal Protection Clause is satisfied as long as there is (1) a plausible policy reason for the classification, (2) the legislative facts on which the classification is apparently based may rationally have been considered to be true by the governmental decisionmaker, and (3) the relationship of the classification to its goal is not so attenuated as to render the distinction arbitrary or irrational. See Gourley v. Nebraska Methodist Health Sys., 265 Neb. 918, 663 N.W.2d 43 (2003). The rational relationship standard, as the *937most relaxed and tolerant form of judicial scrutiny under the Equal Protection Clause, is offended only if a classification rests on grounds which are wholly irrelevant to the achievement of the government’s objectives. Mason v. State, 267 Neb. 44, 672 N.W.2d 28 (2003). When determining whether a rational basis exists for a legislative classification, courts look to see if any state of facts can be conceived to reasonably justify the disparate treatment which results. Gourley, supra.
Applying these standards to the current version of the guest statute, we conclude that § 25-21,237 does not violate the equal protection clause of the Nebraska Constitution. In our cases prior to 1981 concluding that the guest statute was constitutional under an equal protection analysis, the primary legitimate governmental interests behind the guest statute were identified as “the promotion of hospitality, and the prevention of fraud and collusion.” Botsch v. Reisdorff, 193 Neb. 165, 170, 226 N.W.2d 121, 126 (1975). In Botsch, this court found a rational relationship between these governmental interests and the guest statute as it then existed.
In the present case, in response to the Les’ challenge, Lautrup acknowledges that hospitality may no longer be an important interest with respect to the guest statute. Instead, Lautrup relies mainly on the objective of prevention of fraud and collusion as legitimate governmental interests justifying the present version of the guest statute. Lautrup makes further subsidiary arguments, not repeated here, in support of the constitutionality of § 25-21,237. Lautrup also notes that because lawsuits based on intoxication or gross negligence are still permitted under § 25-21,237, it cannot be said that all suits between grandparents and grandchildren are precluded under this statute.
We have reviewed the legislative history of the 1981 amendment to the guest statute. Our review of the legislative history of the 1981 amendment indicates that the prevention of fraud and collusion, rather than hospitality or any other interest, was the main stated justification for the Legislature to retain the guest statute with respect to certain relatives when it repealed the statute as it related to other guests. We have reviewed the current version of the guest statute and the associated legislative history and conclude that the statute’s terms are rationally related to *938the stated interest of preventing fraud and collusion. As noted above, the former version of the guest statute was upheld by this court as rationally related to the legitimate governmental interest of preventing fraud and collusion. See Botsch, supra. The current version of the statute differs from the earlier version in that instead of precluding suits based on simple negligence by all nonpaying guests, it now precludes suits based on simple negligence if brought by nonpaying relatives within the second degree of consanguinity. The group encompassed by the current statute is a subset of the group encompassed by the previous guest statute. Because the universe of nonpaying guests in general has been found rationally related to preventing fraud and collusion, it logically follows that in the absence of compelling developments, a rational subset of that universe remains rationally related to that interest. With respect to the legitimate governmental interest of preventing fraud and collusion, the subset of nonpaying relatives within the second degree of consanguinity is a rational subset of the universe of nonpaying guests. The Legislature could rationally have concluded that close relatives were more likely than other guests to collude with the driver in order to perpetrate a fraud. In rejecting an equal protection challenge to a guest statute that similarly limited its scope to close relatives, the Court of Appeals of Indiana noted that in so limiting the scope,
[t]he legislature may have perceived a greater risk of collusive lawsuits among family members, than among mere acquaintances. Also, a jury may be particularly inclined to indulge in the “Robin Hood” tactic of robbing from the “rich” insurance companies to give to the “poor” victims where the parties are from the same family.
Davidson, by Floyd v. Davidson, 558 N.E.2d 849, 851 (Ind. App. 1990). We conclude that the 1981 amendment of the guest statute to limit the scope to nonpaying relatives within the second degree of consanguinity was rationally related to the stated legitimate purpose of preventing fraud and collusion.
We note that after reviewing the legislative history of the 1981 amendment, the dissent in this case concludes that the “only reason” the guest statute was retained as to close relatives was “because of a political compromise — not because of any *939recognized or asserted classification that is related to a legitimate state interest.” The dissent then cites Distinctive Printing & Packaging Co. v. Cox, 232 Neb. 846, 443 N.W.2d 566 (1989), for the proposition that “[political compromise as a justification, in and of itself, simply does not establish that the classification is rationally related to a legitimate governmental purpose.” In Distinctive Printing & Packaging Co., we rejected a party’s argument that “necessary political compromise in and of itself provides a rational basis for legislative classification.” 232 Neb. at 851, 443 N.W.2d at 571. However, we further noted that “in determining whether a rational basis exists for a legislative classification, courts look to see if any state of facts can be conceived to reasonably justify the disparate treatment which results.” Id. at 852, 443 N.W.2d at 571. We therefore recognized that legislative classifications are often the result of political compromise and determined that although political compromise itself is not a rational basis for legislative classification, a legislative classification that is the result of political compromise may still be justified by an independent rational basis. As stated above, we conclude that the 1981 amendment to § 25-21,237 was rationally related to a legitimate governmental purpose, and evidence that the amendment was in part the result of political compromise does not alter that conclusion.
The Les make various arguments to the effect that the guest statute is unconstitutional because it does not cover all situations in which a driver and passenger might collude and it does not apply to other situations not involving motor vehicles in which persons might collude to defraud insurance companies. However, in the context of equal protection, when the Legislature seeks to inaugurate reforms in the area of economics or social welfare, it need not choose between attacking every aspect of the problem or not attacking the problem at all. Bergan Mercy Health Sys. v. Haven, 260 Neb. 846, 620 N.W.2d 339 (2000). Instead, it is sufficient if the action taken is rationally based and free from invidious discrimination. Otto v. Hahn, 209 Neb. 114, 306 N.W.2d 587 (1981). We find no indication that the Legislature’s decision to minimize opportunity for fraud and collusion by limiting application of the guest statute to certain relatives was a result of invidious discrimination.
*940Further, in economics and social welfare, a statute does not violate the Equal Protection Clause merely because the classifications made by its laws are imperfect. Gourley v. Nebraska Methodist Health Sys., 265 Neb. 918, 663 N.W.2d 43 (2003). The fact that other legislative classification schemes could have been selected does not mean that the scheme chosen is constitutionally infirm. Id. As long as the classification scheme chosen by the Legislature rationally advances a reasonable and identifiable governmental objective, a court must disregard the existence of other methods that other individuals might have preferred. Id. We do not view the Legislature’s actions with respect to the guest statute as amended in 1981 to be wholly irrelevant or unrelated to the stated objectives, and we, therefore, cannot conclude that the Legislature’s actions violated Nebraska’s equal protection clause.
The Les also make various arguments to the effect that the guest statute is not good public policy. In every constitutional challenge, there attaches the presumption that all acts of the Legislature are constitutional, with all reasonable doubts resolved in favor of constitutionality. Otto, supra. In reviewing a statute, we do not pass judgment on the wisdom or the necessity of the legislation or whether the statute is based upon assumptions which are scientifically substantiated. Even misguided laws may nevertheless be constitutional. Id. Therefore, our inquiry under equal protection analysis is not whether we agree with the wisdom or necessity of the law, but whether the law is rationally related to a legitimate governmental interest.
We conclude that the current version of the guest statute is rationally related to the legitimate governmental interest of preventing fraud and collusion. Such interest supports the statute against the Les’ equal protection challenge. We therefore conclude that § 25-21,237 does not violate Neb. Const, art. I, § 3.
Section 25-21,237 Does Not Violate Neb. Const. art. III, §18.
The Les also challenge § 25-21,237 as special legislation in violation of the special privileges and immunities clause of Neb. Const. art. III, § 18. We conclude that § 25-21,237, as amended in 1981, does not constitute special legislation.
We have described the purpose of the constitutional safeguard against special legislation as follows:
*941By definition, a legislative act is general, and not special, if it operates alike on all persons of a class or on persons who are brought within the relations and circumstances provided for and if the classification so adopted by the Legislature has a basis in reason and is not purely arbitrary. ... General laws embrace the whole of a subject, with their subject matter of common interest to the whole state. Uniformity is required in order to prevent granting to any person, or class of persons, the privileges or immunities which do not belong to all persons. ... It is because the legislative process lacks the safeguards of due process and the tradition of impartiality which restrain the courts from using their powers to dispense special favors that such constitutional prohibitions against special legislation were enacted.
Haman v. Marsh, 237 Neb. 699, 709, 467 N.W.2d 836, 844-45 (1991). The focus of the prohibition against special legislation is the prevention of legislation which arbitrarily benefits or grants “special favors” to a specific class. A legislative act constitutes special legislation if (1) it creates an arbitrary and unreasonable method of classification or (2) it creates a permanently closed class. Gourley v. Nebraska Methodist Health Sys., 265 Neb. 918, 663 N.W.2d 43 (2003).
Special legislation analysis is similar to an equal protection analysis, and often the two are discussed together because, at times, both issues can be decided on the same facts. Gourley, supra. As a result, language normally applied to an equal protection analysis is sometimes used to help explain the reasoning employed under a special legislation analysis. Id. But the focus of each test is different. The analysis under a special legislation inquiry focuses on the Legislature’s purpose in creating the class and asks if there is a substantial difference of circumstances to suggest the expediency of diverse legislation. This is different from an equal protection analysis under which the state interest in legislation is compared to the statutory means selected by the Legislature to accomplish that purpose. Id.
When the Legislature confers privileges on a class arbitrarily selected from a large number of persons standing in the same relation to the privileges, without reasonable distinction or substantial difference, then the statute in question has resulted in *942the kind of improper discrimination prohibited by the Nebraska Constitution. Bergan Mercy Health Sys. v. Haven, 260 Neb. 846, 620 N.W.2d 339 (2000). Classifications for the purpose of legislation must be real and not illusive; they cannot be based on distinctions without a substantial difference. Id.
The general test of constitutionality with respect to prohibitions against special legislation is reasonableness of classification and uniformity of operation. Classification is proper if the class at issue has some reasonable distinction from other subjects of a like general character, which distinction bears some reasonable relation to the legitimate objectives and purposes of the legislation. The question is always whether the things or persons classified by the act form by themselves a proper and legitimate class with reference to the purpose of the act. Id.
The Les make no argument that § 25-21,237 created a closed class, and therefore, our special legislation analysis focuses on whether the guest statute created an arbitrary and unreasonable method of classification. We concluded above that § 25-21,237 was rationally related to a legitimate governmental interest and therefore did not violate the equal protection clause of the Nebraska Constitution. Similar considerations and analysis lead us to conclude that the guest statute does not create an arbitrary and unreasonable method of classification in violation of the Nebraska Constitution’s ban on special legislation.
As noted above, this court rejected constitutional challenges to the pre-1981 version of the guest statute. That version made a classification of passengers based on whether they were paying passengers or nonpaying guests, and we concluded, inter alia, that the guest statute as it related to nonpaying persons was constitutional. See Botsch v. Reisdorff, 193 Neb. 165, 226 N.W.2d 121 (1975). The current version of the statute narrows the classification of nonpaying guests to certain nonpaying relatives thought to be more inclined to collude with drivers. As discussed above, the purpose of the statute is to prevent fraud and collusion, and we believe that there is a substantial difference in circumstances surrounding nonpaying relatives as distinguished from other nonpaying persons such that creation of a classification limited to the nonpaying relatives identified in § 25-21,237 is not arbitrary or unreasonable.
*943The guest statute is not the type of law prohibited by the special legislation clause. It does not arbitrarily benefit or grant “special favors” to a specific class and it operates uniformly as to all nonpaying relatives within the second degree of consanguinity. We conclude therefore that the guest statute, § 25-21,237, does not violate the prohibition on special legislation under Neb. Const, art. Ill, § 18.
CONCLUSION
We conclude that the Les failed to establish that the current version of the guest statute, § 25-21,237, violates the Nebraska Constitution, and we therefore conclude that the district court did not err when it concluded that § 25-21,237 was constitutional. The district court did not err when it dismissed the Les’ theories of recovery based on simple negligence. Accordingly, we affirm.
Affirmed.
