MOT exemptions: does your car actually need a test?
5 June 2026·4 min read
The 40-year rule
Vehicles first registered 40 or more years ago do not need an MOT if they have not been substantially changed. That means chassis, body and axles that are essentially like-for-like. A modified classic still needs its yearly test.
The exemption is not automatic. You confirm it when you tax the vehicle, and it only removes the test. The car must still be roadworthy.
The new-car exemption
A brand-new car needs no MOT for three years, and that window stays with the car. A two-year-old used car still has a year left, whoever owns it, and does not need a test until its third birthday.
Vehicles that never need an MOT
Some classes never need a test: most tractors, tracked vehicles, engineering plant and electric invalid carriages, plus a few specialist types. Cars used only on private land also need no test, but the exemption ends at the public road.
