What type of endorsement could expand coverage under a personal auto policy?

The drive other car endorsement specifically enhances the coverage provided under a personal auto policy by allowing the named insured to operate vehicles that are not specifically listed on the policy with coverage similar to what they have for their own vehicle. This is particularly useful for policyholders who may need to drive vehicles belonging to friends or family, or other rental cars, and want to ensure they have the necessary liability protection in case of an accident.

By adding this endorsement, the policyholder extends their personal auto coverage to apply to vehicles they do not regularly use, which helps prevent gaps in coverage and ensures adequate protection in various driving situations. This is especially important since personal auto policies usually limit coverage to listed vehicles only. Other types of endorsements tend to modify or enhance certain aspects of coverage rather than providing the same wide-ranging applicability as the drive other car endorsement.
