Driver's Age Usually, car rental companies require renters to be at least 18 years old, but some firms now require a minimum age of 25 years. For consumers under 25, a credit card is usually required for payment and the rental rate may be slightly higher. Similarly, senior citizens over a certain age may not be allowed to rent cars in some cities. Verify the age restrictions when making your reservation. Although policies vary, many car rental firms allow an immediate relative who is of age to drive the rental car.
Some firms also permit a direct business associate to drive.
Signatures of all drivers and their drivers licenses may be required by the rental firm. There may be a charge for any additional drivers added to the rental agreement. Confirmations Travelers should always receive a voucher or confirmation from their travel agent before departing. This document should have a confirmation number, the car rental company name, type of car requested, flight information and date. If the car rental firm is located outside the airport, a telephone number for the courtesy car pick-up should be provided.
