Iowa Code Title XIII. Commerce [Chs. 505-554D] § 516A.2. 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.
