MOT-Exempt Vehicles: The 40-Year Rule and the V112 Declaration (UK)

Quick answer: Vehicles first registered (or manufactured) more than 40 years ago are exempt from the MOT — it’s a rolling exemption, so more cars qualify every year — provided the vehicle hasn’t been “substantially changed” in the last 30 years. You claim it by declaring exemption (form V112) when you tax the vehicle. Exempt does not mean unaccountable: driving an unroadworthy vehicle remains an offence at any age, and many owners keep voluntary MOTs for exactly that reason.

Who qualifies

• 40+ years since first registration — rolling, checked at the point you tax it.
• No “substantial change” in the last 30 years: different engine type, altered chassis/monocoque, changed suspension or steering type can all disqualify. Period-appropriate replacements and like-for-like restoration are fine.

How to claim it

• Tax the vehicle as normal (many will also be in the free historic tax class from 40 years).
• Declare the exemption — the V112 form at the Post Office, or the equivalent declaration in the online taxing flow.
• Nothing to renew annually beyond taxing; the declaration is your statement that the vehicle qualifies.

Should you still MOT a classic?

Plenty of owners do, voluntarily: it’s a £55-ish independent inspection, insurers like it, buyers trust it, and the public MOT record keeps building — which supports value in a way “trust me” doesn’t. See also what documents add value to a classic.

FAQs

Is exemption automatic at 40 years?
No — nothing changes until you declare it when taxing. Until then the MOT requirement stands.

Who decides “substantially changed”?
You self-assess against the guidance — and you carry the liability if that assessment is wrong. If in doubt, keep testing.
