M - MoT
MoT - The MoT test is a yearly inspection of every car that's three years old or more. The system is run by the Vehicle and Operator Services Agency.
Its purpose is to ensure that vehicles meet legal standards of mechanical safety and also that they comply with emissions regulations.
It is illegal to drive a vehicle over three years old on public roads if it does not have a valid MoT certificate. The document is also needed when renew your road tax.
It is vital to understand that an MoT only says that your car passed road worthiness trials on the day it was tested, so it does not guarantee that your car will remain safe to drive for the rest of the year that it is valid - so make sure you check your tyres, coolant, oil, screen wash and brake fluid levels regularly.
