How old do you have to be to rent a car in Boulder?
Rental vehicle rules in Boulder require drivers to be at least 21. Are you a younger driver? Some restrictions and surcharges could apply. Many rental suppliers impose what is known as a young driver surcharge, which is an additional fee to the cost of the rental car. Restrictions generally apply to the categories of cars young motorists can rent as well. Age limits may differ between providers, so check before booking.

Where can I find a Boulder car rental if I am younger than 25?
If you're a younger driver hoping to book a rental in Boulder, check the terms and conditions of the various car rental companies you're interested in. Some may rent to drivers under the age of 25, some may not. There may be extra costs if you're aged between 21 and 24. To escape any unwanted surprises on pickup, make sure you know if any extra charges apply to you.
Can I drive in Boulder with my current driver's license?
If you don't have a license issued in the United States, you might need to organise an International Driving Permit (IDP) in your country of residence before renting a car. If you find that an IDP is required, be aware that you'll also have to show your current valid driver's license and your passport or other form of ID. Lastly, the credit card that was used to rent the vehicle must match the name on your license and passport in order to finalize your car rental. Some additional requirements for renting a car in the U.S. Are:

  • Age restrictions: You must be at least 25 in most states to be able 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 you book to understand all the terms and conditions.
  • Driving limitations: Make sure you read the fine print before you drive off the lot so you can avoid unnecessary fees. When renting a car in the U.S, it's usually prohibited to cross country borders into Canada or Mexico, drive onto ferries or go off-roading with a rental car. We recommend reading all the rules and regulations before you book!
