If you use your own car to take the practical driving test then you and your car must fulfil certain requirements. If any of these requirements are left unfilled on the day of the test then the driving test will be cancelled without any money being refunded.

The requirements are as follows:

Your car must be insured for purpose. The driving test examiner will need you to sign a declaration stating that your car insurance is in order. If you are unable or unwilling to sign this form then the driving test will not go ahead.
The car must have a current MOT certificate, be fully and properly taxed and be legally road worth in all other respects.
The front passenger seatbelt must be working correctly.
L-plates must be placed at the front and rear of the car.
An unobstructed view to the rear other than by the exterior mirrors must be seen.
An interior mirror for the examiner's use must be fitted.
A head restraint fitted to the front passenger seat must be fitted.
An additional interior rear-view mirror suitable for use by the driving test examiner must be fitted.
Specially adapted cars may be exempt from these requirements.
