Short answer
Only if they're added to the rental agreement as an additional driver. They usually need to come to the counter with their own valid license and meet the age rules. Many companies charge a daily additional-driver fee, though spouses and domestic partners often drive free at major companies, and some states require it. If an unauthorized person drives, your damage waiver and other coverage can be voided.
Sharing the driving on a road trip is common sense — but it only works if the rental company knows about it.
How to add an additional driver
- Add them at the counter at pickup, or later at any of the company's locations.
- They need their own valid driver's license, and must meet the same age and license rules as the main driver.
- They're added to the rental agreement by name.
What it costs
Many companies charge a daily additional-driver fee. Common exceptions:
- Spouses and domestic partners often drive at no extra charge at major companies, and some states require that.
- Loyalty programs and corporate rates sometimes include free additional drivers.
- Young additional drivers can trigger the under-25 surcharge — see renting a car under 25.
Why it matters: unauthorized drivers
If someone who isn't on the agreement drives the car, you're breaking the rental terms. If there's an accident, the rental company's damage waiver can be voided — see what a collision damage waiver is — and your own insurance or credit card coverage may also refuse to pay. You could be personally responsible for the full cost of repairs.
Group trips and family travel
On long drives with a minivan or 7-seater, add every adult who might drive at pickup. It's much harder to fix mid-trip.
Quick checklist
- Add every driver before they drive.
- Bring each driver's license to the counter.
- Check the fee and any spouse exemption.
- Keep a copy of the agreement listing all drivers.
