What is the MOT test, how often is it required, and what are its purposes in the UK?

The MOT (Motor Vehicle Test) is a vehicle safety and environmental test in the United Kingdom. It is an annual requirement for most cars over three years old, with some exceptions such as vehicles under four years old or those used primarily for business purposes. The test's primary purpose is to ensure that cars meet roadworthiness standards, reducing accidents caused by mechanical failures and promoting environmental protection through regular emissions checks.

To be eligible for an MOT, the vehicle must not have been driven on public roads during the test period and must remain stationary at a testing centre or technician's workshop. During the test, mechanics check various components like brakes, lights, steering, and exhaust systems for defects or damage that could compromise road safety. It also includes an emissions test to ensure that pollutants emitted by the vehicle are within legal limits.

The MOT plays a crucial role in maintaining road safety and environmental standards in the UK. By ensuring vehicles undergo regular checks, it helps prevent accidents caused by faulty parts or poor maintenance. Additionally, it encourages car owners to maintain their vehicles properly, reducing harmful emissions from poorly maintained cars.
