Every vehicle in the UK that is more than three years old needs to be tested to ensure that it complies with at least the minimum road safety and environmental standards.
When your vehicle is tested, we look at some important items to see if they meet the legal requirements. Testing ensures that vehicles are in a safe and roadworthy condition at the time of the test, but you should be aware that the MOT certificate is not a guarantee of the general mechanical condition of a vehicle.
The Emissions test is an important part of the MOT. Faults and defects that cause harmful emissions can develop in less than 12 months, so it is important to keep track of your emissions between tests.
