WAV stands for Wheelchair Accessible Vehicle. This means you can travel in the vehicle while seat in your wheelchair
How the Motability Scheme works
Exchange your qualifying mobility allowance for a brand-new car, Wheelchair Accessible Vehicle (WAVWheelchair Accessible Vehicle), scooter or powered wheelchair, so you can enjoy more freedom and independence.
You can start applying online if it’s a car or a WAVWheelchair Accessible Vehicle. Once you’ve had a test drive and you’ve found a vehicle you like, visit a Motability Scheme dealer and they’ll order it for you.
