Do classic cars need an MOT?
Most cars built or first registered more than 40 years ago can be exempt from the MOT, as long as they have not been substantially changed. The exemption rolls forward each year, and the car must still be kept in a roadworthy condition.

How the 40-year rule works
The exemption is a rolling one: each year, cars that reach 40 years old become eligible. Eligibility is based on when the car was built or first registered, whichever is known.
It is not automatic. To be exempt, the car must be registered as a vehicle of historic interest, which you declare when you tax it. Vehicles of historic interest are also usually exempt from vehicle tax, though they still need to be taxed (at a nil rate) each year.
Substantially changed
A car that has been substantially changed in the last 30 years does not qualify. That broadly means changes to the chassis or body shell, the axles or running gear, or the engine that alter its original technical characteristics. Period-correct replacements and changes made to preserve the car are generally fine.
Roadworthy, MOT or not
An exemption from the test is not an exemption from the law. You are still responsible for the car being safe to drive, and driving an unroadworthy vehicle carries a fine of up to £2,500, three penalty points and a possible ban.
For that reason many classic owners choose to have a voluntary MOT each year. It is an independent safety check, and a record of passes is valuable when the car is sold.
Keeping the dates straight
Even exempt cars need their vehicle tax renewed every year. Odomint tracks tax and MOT dates for every car in your garage, including the ones that only come out on sunny weekends.
Buying a classic with no recent MOT
A classic car that has been exempt for years has no recent independent inspection on record. Treat that as a gap in the history rather than a clean bill of health. A voluntary MOT or an inspection by a specialist familiar with the model is money well spent before buying.
Look at the MOT history before the exemption began: the advisories from the last few tests often reveal where the car was weakest. Corrosion, brakes and steering are the usual concerns on older cars, and none of them improves by not being looked at.
Common questions
Does a 40-year-old car need an MOT?
Usually not, if it is registered as a vehicle of historic interest and has not been substantially changed in the last 30 years. It must still be roadworthy.
Do historic vehicles still need to be taxed?
Yes. They are usually exempt from paying vehicle tax, but you still need to tax them at a nil rate each year.
Can I MOT a classic car voluntarily?
Yes, and many owners do, as an independent safety check and a record for when the car is sold.
