If you carry comprehensive and collision coverage, many car insurance companies will extend this coverage to your rental car, though you may still be on the line for the deductible. As each company may have a different policy, you should verify this with your insurer before hitting the road. Some rental car companies also offer rental insurance. The portion that covers damage to the rental vehicle is commonly known as a loss damage — or collision damage — waiver. Supplementary liability covers damage to others that you might cause. Some credit cards also provide coverage, as do a number of companies such as Bonzah and Rental Cover.
