The minimum age to rent a vehicle is 21 years of age. There is no maximum restriction in the United States or Canada. See Exceptions below.

A 'Youthful Surcharge' may be applied to your rental, if you are between the ages of 21 and 24. The average cost is approximately $25.00 per day but can be higher or lower based on the rental location.

If you wish to know the cost of the 'Youthful Surcharge' you may begin the reservation process to determine the exact amount of the fee for the rental location (please remember you will have the option to confirm or cancel the reservation).

Renters 21 through 24 years of age may be restricted to specific car classes. In Michigan and New York, the minimum age to rent is 18 as mandated by these states.

U.S. military personnel and government employees ages 18 or older will not incur a Youthful Surcharge when renting for authorized government travel, but must show the rental location his or her official orders.
