Many renters decline the collision and loss damage waivers offered by car rental firms and assume that coverage afforded by their credit card policies will protect them. But that can be risky.
Declining the rental firm’s CDW or LDW can sometimes have an unintended consequence. Upon learning of an accident or loss, a rental firm may immediately charge its customer’s credit card for the full value of a loss, up to the card credit limit. Be aware that when relying on coverage not sold by the car rental firm, settlement of a loss or damage claim may linger, and the account might be temporarily maxed out until the matter is resolved. Carry a backup card in case an accident or loss occurs far from home.
