If the driver was a Drift-approved secondary driver, they would be covered under the Allstate policy. However, if an accident or incident occurs while an unauthorized party is operating the vehicle, the Drift user who booked the trip and the unauthorized driver will be held responsible for all damages and subsequent claims.
Additionally, the Drift user who booked the trip will incur a fee of $250 and may be removed from the platform as a result of letting an unauthorized driver operate the vehicle.
For information about how to add a secondary driver, visit the "Can another driver operate the vehicle during the trip?" FAQ.
