Also, find out if there are any extra costs. Some businesses will pass on a surcharge to young customers between 21 and 24. Always check the terms and conditions to avoid any surprise fees.
Can I drive in St Mary with my current driver's license?
If you don’t have a driver’s license from the United States, you might need to get an International Driving Permit (IDP) in your country of residence before renting a car in the U.S. If you find that an IDP is required, know that you’ll also have to show your valid driver’s license and your passport or other forms of identification. Lastly, your credit card used to rent the car must match the name on your driver’s license and passport in order to confirm your home. Other things you should know about rental cars in the U.S. Are:

  • Age restrictions: You must be at least 25 in many states in order to rent a car, although in some places the minimum age is 21. We recommend checking local rules and regulations, and with the car rental company before your trip to understand additional terms and conditions.
  • Driving limitations: Make sure you read the fine print before you leave the lot to avoid unnecessary fees. When renting a car in the United States, you usually can’t cross country borders into Canada or Mexico, use car ferries or traverse off-road areas with your rental car. Please read the regulations before you book!
