Confirm with your travel agent, the U.S. State Department, or a Netherlands tourist organization that laws have not changed regarding driving in the country with a U.S. driver's license.
Ensure that your driver's license is valid and up to date. If you are traveling for less than 180 days, you can drive on a normal U.S. driver's license without making any special arrangements.
Discuss the situation with a car rental agency if you will be renting a car. Many such agencies charge an additional fee for drivers under age 25 and in some cases, may not allow you to rent at all.
