Yes, a driver under 21 can drive a rental car, but it is extremely difficult and expensive with major rental companies. Most national chains like Enterprise, Hertz, and Avis have a minimum rental age of 21. If you find a company that rents to 18-20 year olds, you will face a mandatory Young Driver Surcharge—a daily fee that can significantly increase your rental cost—and likely have restrictions on the vehicle classes you can rent, often excluding premium SUVs, luxury cars, and minivans.
The policies and associated costs vary significantly by company and even by location. For example, some corporate-owned airport locations may adhere strictly to a minimum age of 21, while a few independent, off-airport franchise locations might be more flexible. The table below outlines the general policies you can expect, but you must verify directly with the specific rental office.
| Rental Company | Typical Minimum Age | Young Driver Surcharge (Approx. Daily) | Common Vehicle Restrictions |
|---|---|---|---|
| Hertz | 20 (at select locations) | $25 - $35 | Premium, Luxury, Minivans |
| Enterprise | 21 (18 in NY, MI; 20 in CA) | $25 - $30 | Full-size and above, Specialty vehicles |
| Avis | 21 (18 in NY; 20 in CA) | $27 - $35 | Premium, Luxury, Convertibles |
| Budget | 21 (18 in NY; 20 in CA) | $27 - $35 | Full-size and above, Specialty vehicles |
| Fox Rent A Car | 18 | $25 - $30 | Standard SUVs and above |
Beyond age and fees, you'll need a valid driver's license held for at least a year and a major card in your name for the security deposit. Debit cards are often not accepted for young drivers. Your best strategy is to call local rental offices directly, as franchisee rules can be more lenient than the corporate policy. Alternatives include using a peer-to-peer car sharing service like Turo, where individual car owners set their own age requirements (often 18+), or exploring non-traditional rental companies like Fox or Sixt, which may have more accommodating policies.

It's a real hassle, honestly. I tried when I was 20 for a road trip. The big names all said no unless I was 21. I finally found a smaller, local rental place that agreed, but they charged me an extra $30 a day just for being young. On top of that, I was stuck with a basic compact car—no SUVs or anything fun. It added up fast. My advice? Call around to the smaller, non-airport locations. Be prepared to pay a premium.

Focus on the specifics. The challenge isn't just age; it's the "Young Renter Fee." This surcharge can be $25-$35 per day. Your choice of vehicles will also be limited—often to economy or compact cars. You'll need a valid license you've held for over a year and a card (not a debit card) for the hold. Start by searching for "car rental under 21" in your specific city and be ready to provide all your documentation upfront.

From a purely logistical standpoint, your most viable option may be peer-to-peer car sharing platforms. Services like Turo connect you with private car owners, and many list vehicles for drivers 18 and older. The process is similar to Airbnb for cars. You can often find a wider variety of vehicles, and the young driver fees, if applicable, are typically more transparent and sometimes lower than traditional rental companies. Always read the owner's profile and rental requirements carefully before booking.

Look, it's possible but expect major hurdles. The big players—Enterprise, Hertz—will usually turn you away. Your target should be independent franchise locations or companies like Fox Rent A Car. The single most important thing is to call the actual location you plan to rent from. Don't on website information alone. Ask them three questions directly: "What is your absolute minimum age to rent?" "What is the exact daily young driver fee?" and "What vehicle categories am I allowed to choose from?" Getting answers to these will save you a lot of time and frustration.
