This depends on where you would like to rent a car. Though you can rent a car at the age of 18 in many European countries and the states of New York and Michigan in the United States, in many locations you must be 21 to rent a car. You can conveniently check this by entering your age before clicking 'Search now'.
Note that most rental suppliers charge an additional Young Driver Fee for renters under the age of 25, though this age varies by supplier and location. If you enter your age before searching, we include this fee in the total, allowing for the simplest comparison.
