OPALA, J.
T1 The dispositive question tendered on certiorari is whether an automobile ability policy exclusion, which operates to deny all coverage to a named insured who is injured while riding as a passenger in the insured vehicle, violates the legislative policy underlying Oklahoma's compulsory insurance law. We answer in the affirmative, but only insofar as the injured person is left sans the minimum mandated coverage.
[767]*767ANATOMY OF LITIGATION
T2 On 22 September 1993 Glinda Hartline ("Glinda"), a passenger in a 1975 Ford driven by her husband, James Hartline ("James"), sustained bodily injuries in an automobile accident caused by the latter's negligence. (linda brought an action for damages against James. The trial court entered judgment for (linda in the amount of $7,000 to be satisfied solely from the proceeds of a liability insurance policy issued by Mid-Century Insurance Company ("Mid-Century"). The policy provided coverage in the minimum amount required by Oklahoma's compulsory insurance law.1 At the time of the accident, Glin-da and James were married to each other and residing in the same household.
T3 The insurance policy in question was issued on 20 September 1998. Glinda, who was not present when James applied for the policy, did not sign the application form. James alone rejected uminsured motorist coverage. Although the declarations page of the policy lists both James and Glinda as named insureds and billing statements were subsequently sent in both their names, the imswrer's internal date sheet identifies James alone as the named insured. Title to the 1975 Ford (and its registration) was in James's name. Neither the title to, nor the registration of, any other motor vehicle stood in Clinda's name.
T4 Glinda brought a postjudgment garnishment proceeding against Mid-Century, which denied liability,. The insurer then moved for summary judgment. Citing as controlling authority this court's pronouncement in Looney v. Farmers Insurance Group,2 the insurer argued that Glinda, as a named insured under the policy, was validly excluded from liability coverage. In response, Glinda argued that Looney no longer controlled the validity of the exclusion in question. Instead, she urged that the insurance proceeds were available to her because our more recent decision in Nation v. State Farm Insurance Company3 had invalidated the policy exclusion relied on by Mid-Century. While awaiting a ruling on the summary judgment motion, the parties prepared a stipulation of facts and submitted the case for a bench trial. Judgment was entered for Glinda; Mid-Century appealed. The Court of Civil Appeals, Div. IV, (COCA) reversed. Agreeing with Mid-Century that Looney was the controlling authority, COCA held that Mid-Century's policy exclusion for bodily injwry to an insured was valid and relieved the insurer of liability for Glinda's injuries. Having granted Glinda's certiorari petition, we now vacate COCA's opinion and affirm the nisi prius judgment.

THE "INSURED PERSON" EXCLUSION IN MID-CENTURY'S POLICY
T6 The Mid-Century policy here under review provides in pertinent part:
[768]*768PART I-LIABILITY
Coverage A-Bodily Injury
Coverage B-Property Damage
We will pay damages for which any insured person is legally liable because of bodily injury to any person and property damage arising out of the ownership, maintenance or use of a private passenger car, a utility car, or a utility trailer. (emphasis in original denoting defined terms)

Exclusions

11.2. Liability for bodily injury to an insured person. (emphasis in original denoting defined terms)
17 The policy defines an insured person-for purposes of both the liability coverage and exclusionary clause provisions-as (1) the named insured listed on the declarations page, (2) that person's spouse if a resident of the same household, and (3) relatives of either residing in the same household.5
18 Mid-Century argues the quoted policy exclusion relieves it of liability to Glinda. This is so because she falls within the exelud-ed class as a named insured on the declarations page of the policy. The insurer contends that this court's pronouncement in Looney, which affirmed the validity of an exclusionary provision barring recovery by a named insured, compels today a decision in its favor. Glinda, on the other hand, contends that Looney is no longer the controlling authority on the validity of named insured/household exclusionary clauses, having been supplanted by this court's more recent pronouncement in Nation. The latter decision, she urges, teaches that named insured/household exelusionary clauses are void as contrary to the public policy that underlies compulsory liability insurance.

NEITHER LOONEY NOR NATION ADEQUATELY ADDRESSES THE OVERBROAD EXCLUSION CLAUSE IN MID-CENTURY'S POLICY
19 In Looney we were presented with facts quite similar to those in the case at hand. Nita Looney was injured while riding as a passenger in a car owned and driven by her husband, with whom she was then living. The accident was Mr. Looney's fault, and Mrs. Looney obtained a judgment against him. She then brought a postjudgment garnishment proceeding against the vehicle's insurer, Farmers Insurance Group (Farmers), which denied liability based upon a policy exelusion for bodily injury to (1) any member of the insured's household except a servant, or (2) the named insured. The policy defined a named insured as the insured named on the policy's declarations page and that individual's spouse if a resident of the same household. Mrs. Looney was arguably excludable both as a named insured and as a member of the insured's household.
110 Mrs. Looney argued that Farmers exclusionary provision was unenforceable because it violated the public policy of the state expressed in Oklahoma's Financial Responsibility Act (the Act).6
Considering for the first time the requirements of the then newly enacted Article VI of the Act, which mandated lability insurance,7 the court held that its provisions were [769]*769silent on the matter of policy exclusions.8 Instead, the opinion turned to § 7-824(e),9 a provision found in Article III of the Act, and treated it as determinative of an exclusion's validity for an Article VI-mandated policy.10 After examining that provision in detail,11

IV
NEITHER LOONEY NOR NATION ADEQUATELY ADDRESSES THE OVERBROAD EXCLUSION CLAUSE IN MID-CENTURY'S POLICY
19 In Looney we were presented with facts quite similar to those in the case at hand. Nita Looney was injured while riding as a passenger in a car owned and driven by her husband, with whom she was then living. The accident was Mr. Looney's fault, and Mrs. Looney obtained a judgment against him. She then brought a postjudgment garnishment proceeding against the vehicle's insurer, Farmers Insurance Group (Farmers), which denied liability based upon a policy exelusion for bodily injury to (1) any member of the insured's household except a servant, or (2) the named insured. The policy defined a named insured as the insured named on the policy's declarations page and that individual's spouse if a resident of the same household. Mrs. Looney was arguably excludable both as a named insured and as a member of the insured's household.
110 Mrs. Looney argued that Farmers exclusionary provision was unenforceable because it violated the public policy of the state expressed in Oklahoma's Financial Responsibility Act (the Act).6
Considering for the first time the requirements of the then newly enacted Article VI of the Act, which mandated lability insurance,7 the court held that its provisions were [769]*769silent on the matter of policy exclusions.8 Instead, the opinion turned to § 7-824(e),9 a provision found in Article III of the Act, and treated it as determinative of an exclusion's validity for an Article VI-mandated policy.10 After examining that provision in detail,11 the court concluded that it did not prevent Farmers from excluding Mrs. Looney who, it was noted, was a named insured under the policy and not just a member of Mr. Looney's household.12
{11 Despite the factual similarities between Looney and the instant litigation, we decline to rest today's decision on the earher case. There are times when it becomes necessary to reassess our commitment to the binding foree of a prior holding.13 This is such a time. Since its enactment in 1976, the compulsory insurance law has undergone numerous amendments and enhancements.14 [770]*770This metamorphosis, together with the judiciary's gradual unfolding of the public policy that underlies the law's enactment,15 has largely robbed Looney of its rationale and justification. Moreover, in Young v. Mid-Continent Casualty Company,16 this court expressly disapproved of Looney's reliance on an Article III provision to determine the validity of an exclusion in an Article VI-mandated insurance policy.17 Because (a) the court has departed from the reasoning on which Looney was based, and (b) the compulsory liability insurance law has since its Looney-era infancy stage developed into a more comprehensive regime of law-mandated insurance coverage, the rule in Looney can no longer be regarded as a complete expression of Oklahoma law's current stance toward permissible exclusions from mandatory liability insurance coverage. In short, Looney is to be treated as overruled.
112 We also reject Glinda's contention that Nation v. State Farm Insurance Company'18 controls the issue before us. The policy under review in that case provided no coverage for bodily injuries to an insured or any resident family member of an insured. It defined an insured to include resident relatives of the named insured or of the named insured's spouse. The person whose exelusion was sought by the insurer was the insured's five-year old son, who fell within the exclusion both as an insured and as a resident fomily member of an inswred. We held the exclusionary clause unenforceable "insofar as it attempts to defeat the legislature's mandate of a minimum amount of liability insurance coverage available for persons in the position of the deceased passenger here." (emphasis added)19 This indeterminate language did no more than invalidate the exclusionary clause there in contest without providing any gauge for determining invalidity in future cases. Nation does not support Clinda's expansive view of public policy that would favor broad exelusion invalidation flowing from our compulsory insurance law.
113 In sum, neither Looney nor Nation adequately addresses overbroad exclusion clauses in automobile policies that adversely affect the "named insured" or "members of the household." We welcome the opportunity [771]*771presented here-where the named-insured and household exclusions are merged into a single "insured exclusion" clause-to pronounce a standard for distinguishing between permissible and impermissible exclusions in Hability policies issued in compliance with Oklahoma's compulsory insurance law.
V
THE COMPULSORY INSURANCE LAW
114 The provisions of 47 O.S. Supp. 1993 § 601(C)(1) prohibit the operation of any motor vehicle in this state unless it is insured or secured "for the payment of loss resulting from the imposed by law for bodily injury, death and property damage sustained by any person arising out of the ownership, maintenance, operation or use of the vehicle." (emphasis added) 20
115 As originally enacted the compulsory insurance law did not make any reference to exclusionary provisions.21 That state underwent a change when in 1982 the law was amended to authorize the inclusion, in a policy's omnibus clause,22 of "exclusions in accordance with existing law".23 At the same time the legislature added another provision that implicitly sanctions the exclusion of named individual as an insured driver.24 Without deciding whether by its 1982 amendments the legislature intended merely to authorize exclusions from the omnibus clause and of named individuals as insured drivers and no others, it is fair to say that the compulsory insurance law does not plainly and unambiguously sanction or prohibit other types of exclusions. The statute's references to exclusions do not explicitly address the validity of an exclusion based on the kinship of the harmed individual to an otherwise insured tortfeasor whose utilization of the insured vehicle at the time of the accident is one that stands covered by the policy.
116 Even in the absence of a violation of a law's express provision, an exelusion may nonetheless be invalid for nonconformity to the policy of the law. The principal purpose of law-mandated liability insurance is the protection of the public from the financial hardship which may result from the use of automobiles by financially irresponsible persons.25 To effectuate this policy, any vehicle [772]*772operating on the roads of this state must be secured against liability to innocent victims in the event harm occurs from its negligent operation.26 This clearly articulated public policy overrides contrary private agreements that restrict coverage where the contractual strictures do not comport with the purpose of the Act.27
(17 Extant jurisprudence consistently holds that insurance policy clauses which operate to deny coverage to the general public are void as contrary to statutorily articulated public policy.28 Hence, clauses which would exclude from coverage all potential claimants have been uniformly invalidated.29 Yet the same jurisprudence also teaches that the legislative intent in enacting compulsory liability insurance was not "to eliminate all possible bargaining - regarding - liability exclusions which may be contained in the required liability insurance policies."30
118 Family exelusions potentially affect a sizable portion of Oklahoma's population. Almost everyone may plausibly be placed within the excluded class under some relative's policy. Unrestricted application of family exclusions means that seriously injured accident victims will be left with no secured source of compensation for their injuries.
€ 19 Our sister states generally have either completely validated or completely invalidated named imsured and household exclusionary clauses.31 We view this approach as undesirable because it needlessly limits the contractual flexibility of both parties. It is possible to fashion a standard which retains an appropriate element of bargained-for coverage (or exclusion) of family members without sanctioning the exclusion of an overly broad class of persons exposed to potential harm.
120 The solution lies in the interaction of liability insurance and uninsured mo[773]*773torist coverage, the two components of an increasingly integrated system of automobile insurance.32 We hold that the household and named insured/insured exclusions are invalid only when they operate to deny all coverage to an injured resident family member. - It is the insurer's responsibility to assess whether its policy's exclusionary provision will have this effect. Compliance with this pronouncement imposes on the insurer the duty to provide in its policy for at least the minimum mandated coverage. This may be in the form of either liability or uninsured motorist coverage. In short, when an applicant rejects uninsured motorist coverage 33 in a policy which excludes resident family members from liability coverage, the insurer must inform itself by appropriate inquiry whether those who would fall into that policy's exelud-ed class are covered by their own uninsured motorist coverage or by some other indemnity. Those persons who do not own a car will rarely, if ever, have purchased their own uninsured motorist coverage, but one's car ownership alone is no guarantee that there is the requisite coverage. Absent some explicit provision in the policy which affords them the minimum protection, wrongly excluded persons-persons not secured by uninsured motorist coverage-will be deemed insured to the very limit of the insured's liability protection.34
1121 In order to afford insurers ample notice and opportunity to recast liability exclusions or afford UM offers to those who may be impermissibly excluded, the full impact of the new rule which places limits upon the enforceability of exelusions from coverage shall be applied only to those claims which arise after twelve months from the date mandate is issued in this cause. As for this lawsuit and for all litigable claims that have or will have arisen before the date of mandate herein, as well as for those which shall arise during the twelve-month period immediately following the mandate's issuance, improperly excluded spouses and resident family members shall be deemed covered solely to the extent of the statutorily-mandated minimum - amount-$10,000 for each person and $20,000 for each accident.35
VI
SUMMARY
122 Oklahoma jurisprudence teaches that clauses in insurance policies which leave an innocent third-party victim of the insured's negligence without any insurance protection are void as contrary to statutorily articulated public policy. James rejected in the instant case uninsured motorist coverage on behalf of himself and Glinda, and Glinda did not own another insured vehicle which could have provided her with uninsured motorist coverage. Because the exclusion in Mid-Century's policy operated to deny Cilinda all coverage, it is unenforceable as void for [774]*774breach of the law's policy.36
