delivered the Opinion of the Court.
In January, 1987, appellants Emile Fe-ghali and Sirvart Feghali, husband and wife, were driving separate vehicles and were involved in an accident between the two vehicles. The Feghalis resided in the same household and the automobiles were insured by appellee Allstate Insurance Company (“Allstate”) under the same policy. Mr. Feghali filed suit against Ms. Fe-ghali, alleging injuries and seeking damages resulting from the accident. Allstate filed a complaint for declaratory judgment, seeking a determination that it had no duty to defend or indemnify Ms. Feghali because of a “household exclusion” in the insurance policy. 1 By counterclaim, Mr. Feghali argued that if his wife was not entitled to liability coverage due to the household exclusion, Mr. Feghali should be entitled to uninsured motorist benefits under the policy. The trial court ruled in favor of Allstate on all claims and issues.
The Feghalis appealed directly to this court 2 and contend here that the household exclusion violates the purpose and policy of the Colorado Auto Accident Reparations Act, section 10-4-701, et seq., 4A C.R.S. (1987 & 1990 Supp.) (the “Act”). The Feghalis also argue that if we find that the household exclusion is consistent with the Act based on section 10-4-418(2)(b), 4A C.R.S. (1987), section 10-4-418(2)(b) is unconstitutional because it violates the Fegh-alis’ rights to equal protection under both the Colorado Constitution and the United States Constitution. Finally, Mr. Feghali argues that, if the household exclusion is valid, Mr. Feghali is entitled to coverage under the uninsured motorist protection of po^cy- 3 We resolve all issues in favor Allstate.
I.
We held in
Meyer v. State Farm Mut. Auto. Ins. Co.,
The commissioner [of insurance] shall not find that a policy form, certificate, or contract of insurance or rider does not comply with the applicable requirements and standards of this title [10, Insurance,] on the ground that it excludes coverage of claims made by a member of a household against another member of the same household. Such exclusions are in conformity with the public policy of this state.
We then held in
Schlessinger v. Schlessinger,
In our view, the General Assembly’s enactment of section 10-4-418(2)(b) is a clear signal that this court’s interpretation of the legislative declaration of purpose in the Auto Accident Reparations Act [in Meyer'] did not correspond to the purpose actually intended by the General Assembly. [T]he General Assembly[ ] determined] that the public policy underlying the Auto Accident Reparations Act was not intended to abrogate the house *866 hold exclusion clause in automobile liability policies....
Schlessinger,
A.
Schlessinger is dispositive of the Feghalis’ claim that the household exclusion in their policy violates the purpose and policy of the Act. We decided in Schles-singer that the holding in Meyer that household exclusions violated the policy and purpose of the Act was repealed by the adoption of section 10-4-418(2)(b). We see no reason to reconsider that decision. Section 10-4-418(2)(b) legislatively authorized the use of household exclusions in automobile liability policies and household exclusions therefore are consistent with the public policy of the Act.
B.
The parties agree that, because there is no fundamental right or suspect class at issue, the rational basis test applies to the Feghalis’ equal protection challenge to section 10-4-418(2)(b).
See, e.g., Austin v. Litvak,
There are a number of justifications offered for the use of household exclusions. The primary justification offered “is to prevent suspect inter-family legal actions which may not be truly adversary and over which the insurer has little or no control. [Thus,] [s]uch ... exclusions] [are] a natural target for the insurer’s protection from collusive assertions of liability.”
Farmers Ins. Exch. v. Cocking,
Given the possibility of collusion, the California Supreme Court has pointed out that the permission of household exclusion clauses also may serve to benefit the public. In Farmers Ins. Exch., that court stated:
The Legislature reasonably may have concluded that the benefits to the public from automatically including “family member” coverage in all automobile liability policies were outweighed by the probable adverse consequences of such a rule. It is not unreasonable to suppose that substantial increases in premiums would be forthcoming if such coverage were declared mandatory. It may well have been a legislative concern that an increase in the costs of liability insurance might result in an appreciable increase in the number of uninsured drivers to the ultimate detriment of the general public.
Farmers Ins. Exch.,
These justifications for permitting household exclusions are legitimate government *867 objectives which the legislature reasonably may have pursued in enacting section 10-4-418(2)(b). Given these justifications, it is reasonable to distinguish between plaintiffs “related by blood, marriage, or adoption to an insured against whom claim is made if such person resides in the same household as such insured” and plaintiffs who are unrelated or who do not reside in the same household. 5 Thus, section 10-4-418(2)(b) does not violate the Feghalis’ right to equal protection under either the Colorado or the United States Constitutions.
II.
Mr. Feghali also contends that, given a holding that Ms. Feghali is not entitled to liability coverage because of the household exclusion, she was an uninsured motorist and Mr. Feghali is entitled to uninsured motorist benefits under the policy. Mr. Feghali makes two arguments in support of this contention. Mr. Feghali initially contends that denying uninsured motorist benefits to him would contravene the legislative intent and policy of section 10-4-609, 4A C.R.S. (1987) (insurance protection against uninsured motorists). Mr. Feghali also argues that the terms of the Feghalis’ policy do not exclude him from uninsured motorist protection. We address each argument in turn.
A.
In
Terranova v. State Farm Mut. Auto. Ins. Co.,
A claim for uninsured motorist benefits is often predicated on a denial of liability coverage pursuant to a household exclusion. Such a household exclusion would be ineffectual in an automobile liability policy if the insured vehicle exclusion is found to be void as against public policy. Such a finding would be in direct contravention of the explicit statement of legislative policy contained in section 10-4-418(2)(b). See Schlessinger v. Schlessinger,796 P.2d 1385 (Colo.1990) (abolition of Colorado’s doctrine of limited parental immunity in the context of a negligence-based claim for uninsured motorist benefits would contradict the public policy embodied in section 10-4-418(2)(b)).
Id. at 62 n. 4 (citation omitted). As this language from Terranova makes clear, it would contravene the express legislative intent of permitting household exclusions if we were to hold that uninsured motorist protection is available when (a) a policy excludes from uninsured motorist protection an automobile insured under the policy’s liability coverage and (b) the policy denies liability coverage under a household exclusion. Such a holding would nullify the legislatively-sanctioned household exclusion. We therefore reject Mr. Feghali’s argument that legislative intent requires us to permit recovery of uninsured motorist benefits if liability coverage is denied under a valid household exclusion.
B.
The parties agree that the policy limits uninsured motorist coverage to bodi *868 ly injury resulting from accidents involving an “uninsured automobile” and that the policy specifically excludes an “insured automobile” from the definition of an “uninsured automobile.” The question is whether Ms. Feghali's automobile was an “insured automobile” at the time of the accident. The relevant section of the policy includes in its definition of an “insured automobile” an automobile “described in the declarations as an insured automobile to which the bodily injury coverage of the policy applies.” The automobile Ms. Fe-ghali was driving at the time of the accident was included in the declarations as an “insured automobile.” Mr. Feghali nonetheless argues that the denial of liability coverage to Ms. Feghali prevents her automobile from being considered an “insured automobile” at the time of the accident.
We reject Mr. Feghali’s construction of the policy. The listing of the automobile in the declarations as an insured automobile means that Ms. Feghali’s automobile was within the policy’s liability coverage. The fact that Ms. Feghali is denied liability coverage because of the household exclusion does not transform her insured automobile into an uninsured automobile.
See, e.g., Phyall v. Allstate Ins. Co.,
Although
Terranova
is not dispositive of Mr. Feghali’s claim that he is entitled to uninsured motorist protection in this ease,
7
Terranova
provides additional support for our holding that Mr. Feghali is not entitled to uninsured motorist protection. As discussed above, we held in
Terranova
that the denial of uninsured motorist protection to a vehicle insured under an insurance policy’s liability coverage did not violate public policy.
Terranova,
III.
In summary, we hold that the use of household exclusions in automobile liability policies was legislatively authorized by sec *869 tion 10-4-418(2)(b), and household exclusions therefore do not violate public policy. Section 10-4-418(2)(b) does not violate the Feghalis’ right to equal protection under either the Colorado or United States Constitutions. We also hold that Mr. Feghali is not entitled to uninsured motorist benefits. Public policy does not require that Mr. Fe-ghali receive uninsured motorist benefits and the Feghalis’ insurance policy specifically excluded him from uninsured motorist protection.
Judgment affirmed.
Notes
.The household exclusion stated that the liability insurance coverage did not apply to "bodily injury to any pérson who is related by blood, marriage, or adoption to an insured against whom claim is made if such person resides in the same household as such insured.”
. We have jurisdiction of this appeal under C.A.R. 1 and § 13-4-102(l)(b), 6A C.R.S. (1987), because of the constitutional issues raised by the Feghalis.
. The parties agree that Mr. Feghali is entitled to personal injury protection benefits under the policy.
. The Feghalis argue that the prevention of collusion is an insufficient justification because we discounted the collusion argument in
Meyer. See Meyer,
. The Feghalis argued at oral argument that section 10-4-418(2)(b) is overinclusive because it creates an "irrebuttable presumption of collusion” as to parties subject to the household exclusion, thus precluding recovery by people who would not collude. The Feghalis misinterpret the section. Section 10-4-418(2)(b) does not create any such presumption because the section does not require household exclusions.
See
§ 10-4-418(2)(b). Section 10-4-418(2)(b) merely
permits
an insurer and an insured to agree to household exclusions in the insurance policy.

In addition, “in almost all cases, the classification will not be perfectly efficient, but will be either ‘overinclusive’ or 'underinclusive' or both.” G. Stone, L. Seidman, C. Sunstein, M. Tushnet,
Constitutional Law
502 (1986). Mathematical precision is not required. It is well recognized that "[legislative] reform may take one step at a time, addressing itself to the phase of the problem which seems most acute to the legislative mind. The legislature may select one phase of one field and apply a remedy there, neglecting the others.”
Williamson v. Lee Optical,
. Mr. Feghali cites several cases where an insured was permitted to recover uninsured motorist benefits where liability coverage was denied under a household exclusion.
See, e.g., State Farm Mut. Auto. Ins. Co. v. Herron,
. As mentioned above, Terranova did not involve the denial of liability coverage under a household exclusion.
