Where can I find a Boulder car rental if I am younger than 25?
This will depend on the rental car companies located in Boulder. They often have different policies when it comes to minimum ages. If you've found an outlet that does cater to drivers under 25 years of age, bear in mind that additional fees may apply. Conduct some research into what those charges could be before picking up the keys to your vehicle.
Can I drive in Boulder with my current driver's license?
If you don't possess a driver's license from the United States, you may be required to organise an International Driving Permit (IDP) in your home country before renting a car. If you find that an IDP is required, be aware that you'll also have to show your current driver's license and your passport or other form of ID. Lastly, the credit card you used to rent the car must match the name on your driver's license and passport in order to finalize your car rental. Other things you should know about renting a car in the U.S. Are:

  • Age restrictions: You'll need to be 25 in many states in order to rent a car, although in some areas, 21 years and older is allowed. We recommend checking local rules and regulations, as well as with the company you're renting from before your trip to understand all the terms and conditions.
  • Driving limitations: Be sure to read the fine print before you drive off the lot so you can avoid any unnecessary charges. When renting a car in the United States, it's usually prohibited to cross country borders into Canada or Mexico, use car ferries or traverse off-road areas with your car rental. Please read the regulations before booking!
