To rent a car in America, you must be at least 25 years old. You can also rent a car from the age of 21, but you will have to pay a significant surcharge, the ‘young driver fee’. You must have held a driver's license for at least one year. The Dutch driver's license is valid for renting a car in America, provided you do not stay longer than 90 days. Another important rule: bring your credit card. At practically all car rental companies, you need a credit card to get your rental car.
