Car Rental at Luis Munoz Marin Intl. Airport (SJU) from $9

If you don't possess a driver's license issued in Puerto Rico, then you might need to acquire an International Driving Permit (IDP) in your place of residence in order to rent a car. It's also important to note that if you do need an IDP, it has no validity on its own. You'll need to show your current license your passport and other forms of documentation as well. Lastly, make sure the credit card you used to book the rental vehicle matches the name on your license and passport. Some additional requirements for international car rentals are:

• Age restrictions: You need to be 25 or over in many countries to rent a car. If you're younger, it might still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of vehicles available to rent.
• Driving limitations: Make sure you read the rules and regulations before driving away. Usually, you can't cross country borders, drive onto ferries or on certain types of rugged terrain with your rental car.
