Another Greenwheels driver can drive your booked car, but only if you’re in the car as well. You made the booking, so you remain responsible during the trip.
Is the driver not a Greenwheels driver? Then unfortunately, that’s not allowed. We haven’t checked their driving licence.
Do you want someone else to drive your booked Greenwheels car on their own? Then add them as an extra driver. This is only possible if you live at the same address.
