Overview of Underinsured/Uninsured Motorist Coverage

Because a substantial number of owners and operators of cars and trucks in the United States fail to maintain adequate insurance coverage or operate their vehicles without any insurance coverage at all, many motor vehicle insurance policies contain provisions for underinsured motorist coverage, sometimes abbreviated UIM, or uninsured motorist coverage, sometimes abbreviated UM. The intent of such provisions is to give persons insured under auto insurance policies and innocent third persons some of the insurance protection they would have enjoyed if the underinsured or uninsured motorist with whom they are involved in an accident had maintained adequate insurance coverage on an uninsured or underinsured vehicle.

Impact of Riders/Endorsements on Auto Insurance Policies

A rider is a paper attached to a document that amends the document. In an automobile insurance policy, a rider can modify the conditions of the insurance policy. It can increase or decrease the policy's benefits. It can add exclusions from coverage, like a crime exclusion clause. The use of the rider means that the entire policy does not have to be rewritten if a change needs to be made. Riders are also known as endorsements, slips, or rubber stamps.

Setoffs and Uninsured Motorist Insurance Policies

Some state statutes allow uninsured motorist insurance companies to setoff amounts that an insured received from workers compensation, Social Security, and settlements with a liability insurance company. Therefore, if an insured were injured in a car accident while driving in the course of his or her employment, the insurance company could offset the uninsured motorist benefits in the full amount of the insured's workers compensation judgment.

Obligation to Cooperate in Motor Vehicle Insurance

Most automobile insurance policies have a clause that requires an insured to cooperate with the insurance company. The cooperation clause, also known as the cooperation and assistance provision, requires an insured to act in a manner that does not obstruct an insurance company's handling of a claim against an insurance policy. Further, the cooperation clause seeks to stop insureds and claimants from acting together against insurance companies. To breach the cooperation clause, an insured's obstructive conduct must be willful and must prejudice the insurance company.
