OPINION
CRIPPEN, Judge.Appellant, a .retiree who asserted a claim against his No-Fault insurer for $1,472 lost income resulting from an automobile-related injury, disputes the trial court’s application of a policy exclusion for any “work loss” benefits. Appellant contends that respondent insurer was legally obligated to provide coverage for appellant’s lost income. We reverse the trial court and reinstate the income-loss award determined earlier by an arbitrator and vacated by the trial court.
FACTS
Appellant Harold Schroedl, a retiree, purchased an automobile insurance policy *705from respondent American Family Insurance Group in 1992. Asked then whether “work loss” coverage was appropriate, he indicated that it was not. As a result, the policy excluded work loss coverage, defined elsewhere in the policy as coverage for all income and disability benefits mandated by Minn. Stat § 65B.44 (1998). Without further inquiry by respondent as to whether the work loss exclusion was still appropriate, the policy was renewed annually thereafter through 1997.
On December 6, 1997, appellant, then 77 years old, was seriously injured when struck by a car at a gas station.1 At the time of the incident, appellant owned a triplex. His conservator submitted to respondent insurer a claim for $1,472 paid to others for doing work previously done by appellant in his rental enterprise. Respondent denied the claims, reasoning that appellant’s waiver of work loss coverage barred such claims. Appellant then filed for arbitration.
The arbitrator determined that appellant’s 1992 decision to exclude work loss coverage did not relieve respondent of its responsibility, under Minn.Stat. § 65B.491 (1998), to re-determine, upon each policy renewal, if such an exclusion was appropriate. For this and other reasons, the arbitrator determined that appellant was entitled to income loss benefits calculated with regard to his income loss of $1,472.2
The trial court determined, notwithstanding the language of Minn. Stat. § 65B.491, which states that it is the “responsibility” of the insurer to “inquire as to the applicability of this section,” that the statute did not make the insurer “responsible for making certain that persons aged 65 or older are informed about wage loss reimbursement insurance if they could reasonably be expected to benefit from such coverage.” Rather, the court found that the purposes of the statute were fulfilled by any inquiry of the insurance company that would prevent it from avoiding a premium reduction for a senior citizen by claiming that the policy was purchased before the insured reached age 65 and that the insurer had “no way of knowing” whether the insured continued to need income-loss coverage.
ISSUE
Does Minn.Stat. § 65B.491 mandate that No-Fault insurers inquire at each policy renewal if senior-citizen insureds can benefit from wage-loss reimbursement coverage?
ANALYSIS
The interpretation of statutes is a question of law, which this court reviews de novo. Hibbing Educ. Ass’n v. Public Employment Relations Bd., 369 N.W.2d 527, 529 (Minn.1985).
The parties agree that, under certain circumstances, insured senior citizens are to enjoy a premium reduction associat*706ed with eliminating unneeded wage loss coverage. But the parties differ in their approach to the application of the provisions of Minn.Stat. § 65B.491 (1998).3 Respondent suggests that the statute provides senior citizens with nothing more than an option to buy or forgo buying a particular type of coverage and its policy treats the issue as merely an offer for optional coverage, giving the insured “the opportunity to exclude or forgo excluding” work loss benefits. Thus, according to respondent’s reasoning, because appellant elected against work loss coverage in 1992, respondent’s agent did not need to inquire further about work loss coverage when appellant subsequently renewed his policy. This analysis coincides with the trial court’s view of the statute; the court concluded that the insurer had no ongoing responsibility to inquire whether income loss protection was necessary so long as it once gave the insured an opportunity to “keep or exclude” the work loss coverage provided under the policy.
An insurer needs to offer optional coverage only once. See, e.g., Randall v. State Farm Mut. Auto. Ins. Co., 335 N.W.2d 247, 250 (Minn.1983) (holding that insurers are required to make only one legally sufficient offer of optional coverage); Hastings v. United Pac. Ins. Co., 318 N.W.2d 849 (Minn.1982) (implying that optional coverage need not be re-offered at each policy renewal). These two cases involved Minn.Stat. § 65B.49, subd. 6 (1978) (repealed 1980), which stated only that insurers “shall offer” certain optional coverages. As discussed below, the language of Minn.Stat. § 65B.491 mandates something substantially different from an offer of optional coverage and thus makes the present case distinguishable from either Randall or Hastings. According to its plain meaning, the statute in this case, Minn.Stat. § 65B.491, does not deal with optional coverage but distinctly declares a responsibility of the insurer to determine its mandatory obligations when it issues or renews a plan of No-Fault coverage with a person who is age 65 or older.
Consistent with the language of the statute, appellant contends that Minn.Stat. § 65B.491 has implications other than a mere one-time election for or against coverage. Appellant properly suggests that there are two conflicting mandates put upon an insurer by the law. On the one hand, Minn.Stat. § 65B.44 compels a No-Fault insurer to provide “income loss benefits.” On the other hand, Minn.Stat. § 65B.491 compels the insurer to discount its premium and eliminate coverage for an insured senior citizen, respecting income “that the insured will not reasonably be expected to be able to receive.”
To resolve this apparent conflict, Minn. Stat. § 65B.491 explicitly makes insurers responsible for determining, as to each insured, whether they are mandated to provide coverage or mandated to exclude it. Contrary to respondent’s assertion, nothing in Minn.Stat. § 65B.491 suggests that the insured makes any election whatsoever.4 Instead, it is the duty of the insurer to determine whether or not Minn. Stat. § 65B.491 applies. When “issuing or renewing the plan,” it is the “responsibility” of the insurer “to inquire as to the applicability of this section.” Minn.Stat. § 65B.491. The insurer determines its *707mandate, to formulate the mandatory coverage, by inquiring, as a matter of fact, as to what wage loss reimbursement coverage the insured will reasonably “be expected to be able to receive.” In other words, based on information provided by the insured, the insurer determines whether or not it must provide the insured wage loss reimbursement coverage.5 Except through the “inquiry” process of section 65B.491, the statutes make no provision for waiving the mandate of income loss coverage stated in Minn.Stat. § 65B.44.
Respondent contends that if the language of Minn.Stat. § 65B.491 is ambiguous and subject to two interpretations— one requiring only a single inquiry and the other requiring inquiry at each renewal— then this court should find only a duty to perform a single inquiry because “the legislature did not intend to impose a continuing duty upon insurance companies.” This argument is premised on an initial observation that the words of the statute are less than explicit. But we do not see any ambiguity in the statute. The statute pronounces a “responsibility” of the insurer - the party “issuing or renewing” a plan. When the words in a statute are clear and unambiguous, a court must give effect to the plain meaning of the language. Minn. Stat. § 645.16 (1998); Tuma v. Commissioner of Econ. Sec., 386 N.W.2d 702, 706 (Minn.1986). Moreover, an interpretation requiring an ongoing inquiry is ratified by an observation that it is the insurer who is caught between two conflicting statutory mandates when writing policies for senior citizens.
Noting that the second sentence of Minn.Stat. 65B.491 reads, “it is the responsibility of the person issuing or renewing the plan to inquire as to the applicability of this section,” respondent next contends that it is “evident from the use of the disjunctive ‘or’ that the inquiry must only be made once.” To the contrary, the term “issuing or renewing” is in respect to any plan and follows a declaration that “no plan * * ⅜ issued to or renewed” can include certain coverage. Moreover, the statutory mandate for income loss benefits is ongoing, for present and future policy periods. Minn.Stat. § 65B.44. By the declarations of the statutes, the responsibility to inquire arises whenever a plan is issued or renewed.6
DECISION
Because the legislature has imposed on insurers an on-going responsibility to inquire regarding an insured senior citizen’s need for wage loss reimbursement coverage, the trial court erred when it vacated the arbitrator’s award.
Reversed.
. Appellant died as a result of his injuries in December 1998.
. Minnesota Statute § 65B.44 (1998) mandates that an auto insurance policy provide “disability and income loss benefits,” and Minn.Stat. § 65B.43, subd. 6 (1998), defines “income” as:
[SJalary, wages, tips, commissions, professional fees, and other earnings from work or tangible things of economic value produced through work in individually owned businesses, farms, ranches or other work.
Id.
The arbitrator determined that Minn.Stat. § 65B.491, which prohibits providing "wage loss reimbursement” coverage for certain senior-citizen insureds, specifically targets "wage” losses but does not permit exclusion of all “disability and income loss benefits.” In effect, the arbitrator determined that "wage loss” was only a subset of "income and disability loss.”
Without comment on this question, the trial court’s order disavowed the arbitrator’s opinion and allowed the insurer, acting under the “wage loss” provision of Minn.Stat. § 65B.491, to exclude all income loss benefits otherwise mandated under Minn.Stat. § 65B.44. Because we determine that the insurer failed to fulfill its responsibility to inquire as required by Minn.Stat. § 65B.491, we need not determine whether the content of the exclusion was lawfully formulated.'
. Minn.Stat. § 65B.491, enacted in 1987, provides:
After August 1, 1987, no plan of reparation security issued to or renewed with a person who has attained the age of 65 years may provide coverage for wage loss reimbursement that the insured will not reasonably be expected to be able to receive. It is the responsibility of the person issuing or renewing the plan to inquire as to the applicability of this section. The rate for any plan for which coverage has been excluded or reduced pursuant to this section must be reduced accordingly. This section does apply to self-insurance.
. The stance of the insurer, offered to suggest that wage loss coverage is reviewed only once for a retiree, conforms to the insurer’s practice as indicated in this case. In his 1992 application for coverage, appellant was required to check a box that stated his election either to "Keep Work Loss" or "Exclude Work Loss.”
. It is beyond the scope of issues in this case to determine if insurance companies are required to provide a variety of coverages at a corresponding variety of premiums in order to meet the senior insureds’ diverse needs for "wage loss reimbursement” coverage.
. Given the record before this court, it does not appear that appellant’s need for wage loss reimbursement coverage changed greatly between 1992 and the time of his injuries. But this fact did not relieve respondent of its ongoing responsibility to inquire regarding the income that appellant was reasonably "expected to be able to receive.”
