You should demonstrate your ability to securely erect the wheelchair ramps (whatever style of ramp fitted to your vehicle)

Safely install the wheelchair in your vehicle, backing the chair to the `fold down' seats, then securing both wheelchair brakes

Secure seat belts/safety harness and also secure wheel belts/clamps if fitted to your vehicle

Having satisfied yourself that the wheelchair and imaginary disabled person are secure, reverse the process. You will be asked a few questions on the Highway Code, asked to identify a few traffic sign and road markings and asked some general cabology questions - this may include such questions as the length, width or height, tyre pressures, what to do if you found an item of lost property in your cab etc.

It is important that you can demonstrate all the principles of safety and security - if seat belts, wheel belts or wheel clamps etc are fitted then they should be in good working order and applied whatever style of wheelchair accessible vehicle you bring on test.
