If a vehicle has been registered for more than three years, it is an offence to use it on a road without a current test certificate. The tests are carried out by examiners authorised under the Act, at specified vehicle testing stations.

You should note that the holding of a current MOT certificate does not excuse you if you are charged with failure to maintain any parts on the vehicle, (see below).

You should always keep windscreens, windows, lights, indicators, reflectors, mirrors and number plates clean and clear. Ensure that your seat, seat belts, head restraints and mirrors are all adjusted before you drive.

An MOT certificate does not guarantee the road-worthiness of a vehicle after the day on which it is tested.
