Know Your MOT

Classic car MOT exemption: the 40-year rule

Once a car passes 40 years old it can be exempt from the MOT, but the rule has conditions. Here is how it works.

Are classic cars exempt from the MOT?

A car built or first registered more than 40 years ago is usually exempt from needing an MOT, provided it has not been substantially changed in the last 30 years. The 40-year cut-off rolls forward each year, so more cars become eligible over time. Exemption is not automatic on the road: you declare it when you tax the vehicle.

What counts as substantially changed?

A vehicle is substantially changed if key components such as the chassis, body, axles or engine have been altered in a way that changes how it works, in the last 30 years. Changes to preserve a vehicle, or period modifications, generally do not count. If a car has been substantially changed, it still needs an MOT.

Should you still get an MOT?

Being exempt from the MOT does not remove your legal duty to keep the car roadworthy at all times. Many classic owners choose a voluntary MOT anyway, because an independent safety check on an old car is reassuring and can help with insurance and resale. You can book one just as you would for any car.
