Yes, you can rent a car at age 20 in Illinois, but your options will be limited and it will be significantly more expensive. The standard minimum age to rent a car in the U.S. is 21. While a few major rental companies like Hertz offer programs for drivers aged 20 and above, they charge a Young Renter Fee—often $25-$50 per day—on top of the rental cost. You must also possess a valid, non-provisional driver's license that you've held for at least a year and a major card in your name for the security deposit.
The primary challenge for 20-year-olds isn't just finding a company that will allow it, but the financial practicality. The daily young renter surcharge can easily double the base rate of an economy car. Furthermore, your choice of vehicle will be restricted; you typically won't be able to rent premium cars, SUVs, or minivans. It's also crucial to check with the specific rental location, as corporate policies can vary by franchise.
To navigate this, your best strategy is to book directly through the corporate website of a company that has a young renter program. During the online reservation process, you must enter your accurate age. The system will then automatically apply the required fee and only show you the vehicle classes you’re eligible for. Renting from an airport location can sometimes offer more flexibility than a neighborhood branch. Always have your license, credit card, and a second form of ID ready.
| Rental Company | Minimum Age | Young Renter Fee (Approx. Daily) | Vehicle Class Restrictions |
|---|---|---|---|
| Hertz | 20 | $27 - $32 | Standard vehicles and below |
| Enterprise | 21 | $20 - $25 per day | Varies by location |
| Budget | 21 | $27 - $32 per day | Varies by location |
| Avis | 21 | $27 - $32 per day | Varies by location |
| Fox Rent A Car | 20 | $25 - $30 per day | Full-size and below |

It's tough but doable. You'll pay a "young driver fee" every single day of the rental, which adds up fast. I'd stick with Hertz; they're one of the only big names that officially allows 20-year-olds. Don't even bother showing up without a regular driver's license (not a permit) and a card. Debit cards are a no-go for most young renters. Just be ready for the bill to be much higher than the advertised price.

From a logistical standpoint, the key is booking online. When you enter your date of birth on a rental company's website, it will filter your options. If you are 20, Hertz's system will show you eligible cars and include the mandatory surcharge. This upfront transparency prevents surprises at the counter. The process is standardized this way to manage risk and ensure compliance with their policies for younger, less experienced drivers.

I remember trying to rent a car at 20 for a road trip. We called every place in town. Most said no immediately. Finally, we found a Hertz at the airport that agreed, but the daily fee was a killer. The whole thing felt like a hurdle. My advice? Factor in that extra fee from the start—it makes comparing prices honestly really important. And definitely have your own info ready to go.

The exists due to the higher statistical risk associated with younger drivers, which impacts the rental company's insurance premiums. This risk is mitigated through age restrictions and surcharges. For a 20-year-old, the contractual requirement to use a credit card is non-negotiable, as it secures the deposit and any potential damages. Always review the rental agreement carefully for any additional location-specific stipulations beyond the corporate policy.
