The minimum age to rent a car in Colorado is typically 20 years old. However, this comes with a significant catch: almost all major rental companies will charge a Young Renter Fee (often called an underage fee) for drivers between the ages of 20 and 24. While less common, a few rental locations, particularly independent agencies or those near military bases, may rent to 18- and 19-year-olds, but this is the exception and involves even higher fees and stricter conditions.
The widely accepted standard age to rent a car without any extra fees or restrictions is 25. This is a policy set by the rental companies themselves based on risk assessment, not a state law. Colorado state law does not set a minimum rental age; it only requires that a driver be licensed. The real restrictions come from the corporate policies of the rental agencies.
| Rental Company | Minimum Age to Rent | Young Renter Fee (Ages 21-24) | Policy Notes |
|---|
| Enterprise | 21 | ~$20 per day | Renting to drivers under 21 is not permitted. |
| Hertz | 20 | ~$25 per day | Age 20-24 fee applies; must have a valid credit card. |
| Avis | 21 (18 at some locations) | ~$27 per day | Policies can vary by location; 18-20 year olds face higher fees. |
| Budget | 21 | ~$27 per day | Similar to Avis, as they are part of the same parent company. |
| Dollar Rent A Car | 20 | ~$25 per day | Age 20-24 fee applies; premium vehicles may be restricted. |
Before you book, always call the specific rental location directly to confirm their age policy and the exact daily fee. The young renter fee can add a substantial amount to your total cost, so it's a critical factor in your budget. Be prepared to present a valid driver's license and a major credit card in your name for the security deposit.
