Who can drive the car

You, the person who booked, are the primary driver. Nobody else may drive unless they are on the trip's authorized driver list and have completed their own verification.

Letting someone drive who isn't on the list breaks the Terms of Service and voids coverage for the trip. If the car is damaged while they are driving, the charge lands on you.

Adding people

Anyone with a valid license and their own insurance can be added as a driver, up to three per trip. You can add or remove drivers until the trip is finished.

Open your trip from Trips. The Authorized drivers panel shows everyone with their status. Your host sees the same list.
