Travelers who are 21 often face more restrictions when renting a car, but several major U.S. rental brands do permit 21-year-olds to rent vehicles. Policies vary by company, location, and vehicle type, and additional fees or deposit requirements frequently apply. This guide explains which agencies allow 21-year-old renters, what additional costs may apply, and how to improve the chances of a smooth rental experience.
Understanding Age Requirements
Most U.S. rental agencies set a minimum age between 21 and 25. Drivers aged 21–24 are considered underage in many markets and may face restrictions such as limited vehicle classes, higher security deposits, and underage surcharges. In some locations, the minimum age may differ for airport counters versus city locations. Drivers 25 and older generally enjoy standard terms without the underage surcharge. It is essential to verify local policy at the rental location before booking, as rules can vary widely by state and even by franchise.
