In this case, we are asked to decide the validity of the “regular use exclusion” in the plaintiff’s uninsured motorist coverage under G. L. c. 175, § 113L. 1 The case was *451 submitted to a Superior Court judge on a statement of agreed facts, and he granted declaratory relief for the plaintiff. The defendant sought review of this decision in the Appeals Court, and we transferred the case to this court on our own motion.
The following appears from the statement of agreed facts. On January 29, 1983, the plaintiff was involved in an automobile accident on Pleasant Street in Worcester. She suffered serious physical injuries resulting in damage to her person in excess of $50,000. The plaintiff had been a passenger in a 1972 AMC Sportabout that was owned, operated, and insured by her husband, Daniel M. Cardin.
The Sportabout was insured by the defendant. Part Five of the insurance policy written for that automobile provided coverage of up to $25,000 per person for bodily injury to others resulting from an accident for which the plaintiff’s husband was legally responsible. In addition, Part Seven of that policy provided coverage of up to $25,000 per person for bodily injury to the plaintiff’s husband, or to any member of his household (including the plaintiff), caused by an underinsured automobile. 2 The defendant agreed to pay the plaintiff the $50,000 maximum coverage under both of these provisions.
The plaintiff owned a 1979 Chevrolet van, separately insured by the defendant under a policy that included the same under-insurance coverage. The defendant denied liability under this provision. In doing so, the defendant relied on the following exclusion of coverage contained in the plaintiff’s policy: “We will not pay to or for . . . anyone injured while occupying an auto owned or regularly used by you or a household member unless a premium charge for this Part is shown for that auto on your Coverage Selections page.” There was no mention of *452 the 1972 Sportabout owned by the plaintiff’s husband on the Coverage Selections page.
The plaintiff argues that the exclusion is contrary to the language and policy expressed by G. L. c. 175, § 113L. She also claims that in this case the exclusion fails to serve the purpose for which it was intended, and that it deprives her of the substantial economic value of her policy while conferring an unfair benefit on the defendant. We hold that any exclusion to uninsured motorist coverage is contrary to the language and policy of G. L. c. 175, § 113L, and is therefore unenforceable. Accordingly, we affirm the judgment of the Superior Court.
Navigating the tortuous twists of automobile insurance law poses a challenge at least equal to that faced by the uninitiated driver on his first foray into the streets of Boston. For this reason, it is important for us to distinguish what this case does and does not involve. Unlike automobile
liability
insurance, uninsured motorist coverage is not restricted by statute to situations “arising out of the ownership, operation, maintenance, control or use” of the insured motor vehicle. See G. L. c. 90, § 34A. The statute therefore does not limit her recovery to situations involving the motor vehicle she has insured. Instead, uninsured motorist coverage insures persons, wherever they may be, when and if they are injured by an uninsured motorist. As one court has aptly summarized: “[T]he uninsured motorists coverage was applicable if, at the time of sustaining injury, [the plaintiff] . . . was occupying the [automobile] described in his policy, or was on foot, or on horseback, or while sitting in his rocking chair on his front porch or while occupying a non-owned automobile furnished for his regular use .... This so-called uninsured protection is limited personal accident insurance chiefly for the benefit of the named insured.”

In addition, the rule that ambiguous policy language will be construed against the insurer has no application here.

See
Cody
v.
Connecticut Gen. Life Ins. Co.,
*455
The statutory language unequivocally commands that no policy shall be issued without uninsured motorist coverage. The only limits on this coverage which the statute comprehends are that the insured be legally entitled to recover damages, that the tortfeasor be uninsured or underinsured, and that payment not exceed the monetary limit of the insured’s policy. The statute does not refer to exclusions at all, and we will not sanction reductions in coverage for which the Legislature has not provided. Compare Cal. Ins. Code § 11580.2 (West Supp. 1985). To do so would be “wholly inconsistent” with the broad remedial purpose of the statute, and would “permit the insurer to evade mandated coverage by erecting an artificial, arbitrary barrier to recovery.”

v.
Lumbermens Mut. Casualty Co., supra
at 177. The broad language and purpose of the statute are not to be “whittled away by a myriad of legal niceties arising from exclusionary clauses.”
Touchette
v.
Northwestern Mut. Ins. Co.,
This view is consistent with decisions in many other jurisdictions interpreting exclusions to uninsured motorist coverage. See, e.g.,
Alabama Farm Bur. Mut. Casualty Ins. Co.
v.
Mitchell,
*456
We recognize that the effect of our decision will be to allow insured motorists to “stack” their uninsured motorist coverage.
7
We conclude that the propriety of stacking is a policy decision best left to the Legislature, and that the strict command of the statute precludes the insurer’s attempt to avoid stacking uninsured motorist coverage.

This court’s decision in
Royal Indem. Co.
v.
Blakely,
The defendant nevertheless points out that the Legislature delegated to the Commissioner of Insurance the authority to interpret the scope of G. L. c. 175, § 113L. See
Royal Indem. Co.
v.
Blakely, supra
at 90. Therefore, since the Commissioner of Insurance approved the policy containing the exclusion, it is argued that the exclusion must be enforceable. But the Legislature did not intend to insulate the Commissioner’s actions from judicial review. See G. L. c. 175, § 113A. While we will not lightly second-guess the Commissioner’s interpretation of the statute, his approval is “hardly persuasive” where the
*457
exclusion violates the language and policy of the statute.

Lumbermens Mut. Casualty Co., supra
at 178, quoting
State Farm Mut. Auto. Ins. Co.
v.
Maryland Auto. Ins. Fund,
Therefore, we hold that any policy exclusion to uninsured motorist coverage is unenforceable in light of the Legislature’s decision not to sanction such exclusions in the statute. For that reason, we affirm the declaratory judgment of the Superior Court. 9
Judgment affirmed.
Notes
General Laws c. 175, § 113L (1), as amended by St. 1980, c. 532, § 1, provides: “No policy shall be issued or delivered in the commonwealth with respect to a motor vehicle . . . registered in this state unless such policy provides coverage in amounts or limits prescribed for bodily injury *451 or death for a liability policy under this chapter, under provisions approved by the insurance commissioner, for the protection of persons insured thereunder who are legally entitled to recover damages from owners or operators of uninsured motor vehicles ....’’ Under G. L. c. 175, § 113L (2), as amended by St. 1980, c. 532, § 2, uninsured motorists include those who are underinsured.
Since the $25,000 coverage provided by Part Five of her husband’s policy was insufficient to compensate the plaintiff for her injuries, her husband is considered to be underinsured. See G. L. c. 175, § 113L (2).

We express no view whether this rule retains its validity in circumstances where the Commissioner of Insurance drafts the contested language and mandates its inclusion in the policy. See, e.g.,
Lumbermens Mut. Casualty Co.
v.
DeCenzo,
In
Royal Indem. Co.
v.
Blakely,
Courts in many other jurisdictions have struck down exclusions to uninsured motorist coverage regardless of their reasonableness. However, some courts have upheld them in situations where at least the policy underlying
*456
the regular use exclusion was applicable, for example, where the insured uses two or more automobiles but insures only one. See, e.g.,
Rodriquez
v.
Maryland Indem. Ins. Co.,
We also reject as an inappropriate intmsion into the legislative function the idea that we should enforce exclusions which may appeal to us as reasonable or appropriate in a given instance. See
MFA Ins. Cos.
v.
Whitlock,
“Stacking is where a claimant adds all available policies together to create a greater pool in order to satisfy his actual damages.” 12A M.S. Rhodes, Couch’s Cyclopedia of Insurance Law § 45:651, at 207 (2d ed. rev. 1981).
We express no view as to the merits of stacking coverages other than those relating to uninsured motorists.
Having found that the exclusion is unenforceable, we do not decide whether application of the exclusion to this case would render the plaintiff’s uninsured motorist coverage of no substantial economic value. See
Cody
