Vehicles built or first registered more than 40 years ago on a rolling basis do not need an MOT, as long as no ‘substantial changes’ have been made to it in the last 30 years.
Changes can include replacing the chassis, bodyshell, axles, or engine to change the way the vehicle works.
It’s important to know that even if your vehicle is exempt from an MOT, it is still legally required to be roadworthy at all times it’s used on the road.
For this reason, many people choose to undertake an annual MOT in any case.
