Construction — minimum coverage — stacking

1. a. Except with respect to a policy containing both underinsured motor vehicle coverage and uninsured or hit-and-run motor vehicle coverage, nothing contained in this chapter shall be construed as requiring forms of coverage provided pursuant hereto, whether alone or in combination with similar coverage afforded under other automobile liability or motor vehicle liability policies, to afford limits in excess of those that would be afforded had the insured thereunder been involved in an accident with a motorist who was insured under a policy of liability insurance with the minimum limits for bodily injury or death prescribed in section 321A.1, subsection 11. Such forms of coverage may include terms, exclusions, limitations, conditions, and offsets which are designed to avoid duplication of insurance or other benefits. b. To the extent that Hernandez v. Farmers Insurance Company, 460 N.W.2d 842 (Iowa 1990), provided for interpolicy stacking of uninsured or underinsured coverages in contravention of specific contract or policy language, the general assembly declares such decision abrogated and declares that the enforcement of the antistacking provisions contained in a motor vehicle insurance policy does not frustrate the protection given to an insured under section 516A.1. 2. Pursuant to chapter 17A, the commissioner of insurance shall, by January 1, 1992, adopt rules to assure the availability, within the state, of motor vehicle insurance policies, riders, endorsements, or other similar forms of coverage, the terms of which shall provide for the stacking of uninsured and underinsured coverages with any similar coverage which may be available to an insured. 3. It is the intent of the general assembly that when more than one motor vehicle insurance policy is purchased by or on behalf of an injured insured and which provides uninsured, underinsured, or hit-and-run motor vehicle coverage to an insured injured in an accident, the injured insured is entitled to recover up to an amount equal to the highest single limit for uninsured, underinsured, or hit-and-run motor vehicle coverage under any one of the above described motor vehicle insurance policies insuring the injured person which amount shall be paid by the insurers according to any priority of coverage provisions contained in the policies insuring the injured person.
