Car rental companies usually require that you secure a car rental with a credit or debit card. They may deny a car rental or increase your deposit if you have a bad driving record or are younger than 21 or 25 years old.
You typically pay a daily fee for a car rental. If it does not include unlimited mileage, you will pay a surcharge for exceeding limitations. You may also pay for additional drivers. A car rented from the airport may carry an additional airport surcharge. Pick your car from another location when possible.
You can expect to receive a clean car with a full tank of pass. Return it in the same condition to avoid additional charges.
Check you auto insurance and homeowner's policies, credit card agreement and auto club memberships to see if they includes coverage for rental cars. If not, take the insurance offered by the rental company. Otherwise you may become liable for the damages to the car if you have a collision.
