If your vehicle is 3 years or older you are required by law to have an annual safety check, commonly known as an MOT.
The purpose of the MOT is to ensure the vehicle meets the minimum safety level required by law. During the MOT the tester will conduct an inspection and a comprehensive series of checks around the vehicle, including the interior, exterior, under the bonnet and under the vehicle.
If the vehicle passes all MOT checks, a VT20 MOT certificate is issued. However, if the vehicle fails its MOT checks, a VT30 document is issued.
Items that aren’t quite a failure, but will require future attention are listed as 'advisory' items.
