How old do you have to be to rent a car in Boulder?
Drivers 21 and above can hit the highway in Boulder in a home vehicle. If you’re a young motorist, a daily surcharge applies. You’ll usually have fewer car categories to select from, such as economy and compact, and may also be required to buy inclusive insurance. Always enter the correct age of the primary driver when booking to find out if any extra fees or restrictions apply.
What do you need to rent a car in Boulder?
A valid driver’s license and a credit card in the same name. Don’t want to take out the company’s insurance plan? Then there’s a good chance you’ll also need proof of your own coverage. Rules can differ between suppliers, so be sure to read through your policy.
What is the cheapest car rental in Boulder?
The two lowest daily rates recorded in Boulder within the past seven days were AU$88 and AU$130. Now that’s what we’d call a fantastic deal! These rates were available on Expedia, with a holiday home starting date within the next year. Prices and availability are subject to change and additional terms apply.
Can I rent a car for a month or longer in Boulder?
You can, and the wonderful news is suppliers often offer lower rates the longer you rent. Look through our long-term car rental deals in Boulder and drive away with a real bargain.
Where can I find a Boulder car rental if I am younger than 25?
Renting a car if you are under 25 in Boulder often depends on the holiday home provider you choose. Some places apply a surcharge for drivers aged between 21 and 24 years, but other companies may not apply any extra fees for this age range. It’d be smart to understand the terms and conditions of your prospective car rental dealer to avoid any surprise charges at the holiday home desk.
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!
