Every time you rent a car you are asked what kind of insurance you would like. The options are generally to take none, which costs nothing, or you could cover liability insurance, which should cost about $10 per day.
Then you have a variety of options to cover the rental car itself, these prices vary from company to company and state to state. The full coverage option, which includes liability, passengers, and the rental car usually, comes to about $25 to $30 a day.
Credit Card Coverage
Make sure you check with your credit card company and your auto insurance company before you get extra insurance on your rental car. Most insurance companies will cover a rental car depending on your policy. Credit card companies may also cover your rental car so check with them to make sure before you purchase insurance through the rental car company.
Many times people pay extra because the rental car company tells them that their private insurance won’t cover the rental, but in most cases this isn’t true, so do your homework and double check before forking out the extra cash.
