The cost to add an additional driver to a rental car agreement typically ranges from $5 to $25 per day, but it can sometimes be free if the driver meets specific criteria, such as being a spouse/domestic partner or a member of the rental company's loyalty program. The final price is determined by the rental company's policy, the location (state laws differ), and the primary renter's membership status. It's never a flat, universal fee, so you must inquire at the counter.
The primary factor is state law. Some states, like New York, prohibit rental companies from charging a fee for a spouse. Other states allow fees but may have restrictions. Beyond legality, rental companies (Hertz, Enterprise, Avis, etc.) each have their own rules. Being a member of their frequent renter program (e.g., Hertz Gold Plus Rewards, Enterprise Plus) can often waive the fee for an additional driver.
It's crucial to declare all drivers. If an undeclared person drives the car and you have an accident, the rental company's insurance may be voided, leaving you fully liable for all damages. The process is simple: the additional driver must be present at the counter with their valid driver's license and meet the company's age requirements (usually 25 or older, though young driver fees may apply separately).
| Rental Company | Typical Additional Driver Fee (Per Day) | Common Fee Waiver Conditions |
|---|
| Enterprise | $10 - $15 | Spouse/Domestic Partner, Enterprise Plus members |
| Hertz | $13 - $15 | Spouse/Domestic Partner, Hertz Gold Plus Rewards members |
| Avis | $13 - $15 | Spouse/Domestic Partner, Avis Preferred members |
| Budget | $10 - $15 | Spouse/Domestic Partner, Budget Rapid Rewards members |
| National | $0 (for most renters) | Spouse/Domestic Partner, Emerald Club Execuitive members |
Always check the terms and conditions of your specific reservation and ask the rental agent directly. The fee is almost always added to the total cost of the rental, not paid in cash at the counter.
