*827 Opinion
Defendant David Neilson Chalk (Chalk) appeals a judgment in favor of plaintiff West American Insurance Company (West American) on West American’s complaint seeking subrogation from Chalk for uninsured motorist benefits paid to West American’s insureds. Chalk contends the three-year statute of limitations of Insurance Code 1 section 11580.2, subdivision (g), should not apply to allow West American to prosecute the claims of its insureds to which it has become subrogated where the insureds failed to sue Chalk within the one-year statute of limitations applicable to personal injuries. We conclude section 11580.2, subdivision (g), properly allows West American to seek subrogation of uninsured motorist benefits paid to its insureds within three years of paying those benefits. Accordingly, we affirm the judgment.
Factual and Procedural Background 2
On January 26, 1983, Chalk was uninsured when the car he was driving hit another car, injuring Rae Caplan, Allen Wilson and Marilyn Wilson and damaging Rae’s car. Rae, Allen and Marilyn were covered insureds under the terms of a West American insurance policy issued to Harold Caplan. That policy contained provisions obligating West American to pay all sums which any person insured should be legally entitled to recover as damages from the owner or operator of an uninsured automobile causing injury to such person.
As a result of the accident, West American paid Rae $9,274.25 for her injuries on July 18, 1983, and also paid $4,583.36 for damage to her car. 3 On January 25, 1984, Allen and Marilyn filed an action against Chalk for personal injuries, although the action was never served on Chalk. Later, Allen settled his uninsured motorist claim with West American for $6,500 and Marilyn settled her claim for $6,000.
On August 1, 1984, West American sued Chalk to recover the amounts paid to its insureds under the policy. Chalk alleged West American had no direct claim of liability against him. After a court trial on stipulated facts, judgment was entered in favor of West American.
*828 Discussion
Because the parties submitted the case to the trial court on stipulated facts, the issues presented on appeal involve questions of law.

State Farm Mut. Auto. Ins. Co.
(1970)
I
Section 11580.2 sets forth the statutory scheme for uninsured motorist coverage. In order to recover from his or her own insurer under an uninsured motorist provision, the insured must, within one year of the accident, either file an action against the uninsured motorist, 4 agree with the insurer as to the amount due under the policy, or formally institute arbitration proceedings. (§ 11580.2, subd. (i).) Once the insured has complied with subdivision (i) and the insurer has paid uninsured motorist benefits, section 11580.2, subdivision (g), specifically provides that the insurer may bring a subrogation action against the uninsured motorist: “The insurer paying a claim under an uninsured motorist endorsement or coverage shall be entitled to be subrogated to the rights of the insured to whom such claim was paid against any person legally liable for such injury or death to the extent that payment was made. Such action may be brought within three years from the date that payment was made hereunder. ” (Italics added.) Thus, the insurer has three years from the date of payment to its insured to bring a subrogation action against the uninsured motorist.
According to the stipulated facts here, Rae Caplan settled her uninsured motorist claim with West American under section 11580.2, subdivision (i), within one year of the accident. Allen and Marilyn Wilson preserved their *829 rights to pursue their uninsured motorist claims under section 11580.2, subdivision (i), by filing suit against Chalk within one year of the accident and later settled their claims with West American. West American was then entitled to subrogation from Chalk for the amounts it paid to Rae, Allen and Marilyn. (§ 11580.2, subd. (g).)
II
Chalk does not dispute that West American brought its subrogation action against him within three years of paying its insureds. Rather, Chalk contends the three-year statute of limitations of section 11580.2, subdivision (g), should not allow West American to prosecute the claims of its insureds to which it has become subrogated where the one-year statute of limitations applicable to the insureds’ personal claims against Chalk has expired. Stated another way, he asserts the Legislature did not intend that an uninsured motorist be liable for the consequences of his or her motor vehicle accident for a period three times longer than an insured motorist would be liable, nor did the Legislature intend that an insurance company be entitled to assert claims as a subrogee after its subrogors can no longer assert those claims for themselves.

Chalk asserts that under general principles of subrogation, the insurer as subrogee can have no greater rights than the insured as subrogor. However, because the subrogation rights provided by section 11580.2, subdivision (g), are statutory and not common law rights

Without benefit of argument, Chalk asserts the three-year statute of limitations of section 11580.2, subdivision (g), is unconstitutional. However, in determining the constitutional validity of section 11580.2, subdivision (g),

(D'Amico
v.
Board of Medical Examiners
(1974)
In the context of uninsured motorist protection, the Legislature has determined that insurance companies must offer their insured protection against loss caused by motorists who, in violation of state law, drive without maintaining financial responsibility. (See Veh. Code, §§ 16020, 16021.) Under section 11580.2, subdivision (i), those injured by uninsured motorists have one year to make a claim against their carriers—the same amount of time the injured insured would have to file suit against the driver causing the accident if that driver were insured. Once the insurer has compensated its own insured for damages caused by the uninsured driver, the insurer may subrogate against the uninsured driver.
Statutes of limitations are intended to vary, reflecting “the legislative policy of differing the periods of limitation according to the degree of permanence of the evidence and the relative favor with which the Legislature views the type of claim or class of litigants. [Citation.]”

Notes
All statutory references are to the Insurance Code unless otherwise specified.
The facts are taken from the parties’ statement of agreed facts presented to the trial court.
On appeal, Chalk does not dispute the property damage portion of the insurance claim which is governed by the three-year statute of limitations of Code of Civil Procedure section 338.
Where the insured files a personal injury action against an uninsured motorist under section 11580.2, subdivision (i), “notice in writing of the suit shall be provided the insurer of the insured plaintiff within a reasonable time after the insured knew or should have known of the uninsured status of the motorist, but in no event shall that notice be required before one year from the date of the accrual of the cause of action on which the claim is based. . . .” (§ 11580.23, subd. (a).)
In support of his argument, Chalk cites several cases discussing equitable subrogation. However, because uninsured motorist subrogation is statutory and not derivative
