The first step is to check your auto insurance policy, or contact your provider to see what type of coverage for rental cars may already be included in your personal auto insurance policy. If you carry comprehensive and liability coverage on your personal car, coverage typically will extend to your rental car within the United States.
If you’re renting a car in the U.S. of similar value to your personal car, in all likelihood your auto insurance coverage will be adequate for the rental. But if you’re off to a blowout beach weekend in a slick set of wheels like a Corvette Stingray and you’re leaving your 2008 Subaru Forester at home, purchasing the extra auto insurance coverage offered by the rental company may be a good idea.
