In addition, some credit cards cover
damages to many basic types of rental cars. It's a good idea to
check into your existing coverages before your trip. In most states,
car rental companies are prohibited from refusing to rent you a car
unless you purchase the additional insurance, but many companies
still try to do it. The coverage's that you can get are all
optional. Combined, they can add up to $30 per day to the rental
bill. Each coverage protects against a different risk, but your car,
home, life, or health insurance policies, or your credit card, may
provide all or part of the protection you need, particularly when
they are combined with the minimum insurance the car rental company
is required by law to provide as a part of every rental.
