MOT exemption for cars over 40 years old

A car does not need an MOT in Great Britain if it was built or first registered more than 40 years ago and has not been substantially changed in the last 30 years. The exemption rolls forward, so more cars qualify as time passes. You do not apply for it on its own: you declare it when you tax the car. The owner must still keep the car roadworthy, and can choose to have a voluntary MOT anyway.

Who qualifies

Under the Department for Transport criteria, a car does not need an MOT if both of these are true:

• it was built or first registered more than 40 years ago
• no substantial changes have been made to it in the last 30 years

Cars that meet both tests are called vehicles of historical interest (VHIs). The rolling 40-year exemption came in on 20 May 2018. Before that, only cars first registered before 1960 were exempt, and those cars are still included.

Because the rule is based on age, it rolls forward. A car first registered on 1 June 1986, for example, turned 40 on 1 June 2026, so from then on it can qualify if it has not been substantially changed.

This guide covers the rules in England, Scotland and Wales. Northern Ireland has its own MOT scheme, run by the DVA.

What counts as a substantial change

A change is substantial if the technical characteristics of the main components have been altered in the previous 30 years, unless the change is on the list of acceptable alterations. For cars, the main components are:

• Chassis or frame. A replacement of the same pattern as the original is not a substantial change.
• Monocoque bodyshell, including sub-frames. Again, a replacement of the same pattern is fine.
• Axles and running gear. Changing the type or method of suspension or steering is a substantial change.
• Engine. Alternative cubic capacities of the same basic engine, and alternative original equipment engines, are not substantial changes.

Some changes do not count, even if they touch those components. The guidance lists, among others:

• changes made to preserve the car because original-type parts are no longer reasonably available
• changes of a type that can be shown to have been made while cars of that type were in production, or within 10 years of the end of production
• changes to axles and running gear to improve efficiency, safety or environmental performance
• changes made to a vehicle that was previously used commercially, if you can prove they were made while it was used commercially

If you cannot confirm that a car has not been substantially changed, the guidance says you must not claim the MOT exemption.

Cars that still need an MOT

Even over 40 years old, a car still needs an MOT if it:

• has been substantially changed in the last 30 years
• has a registration number with a Q prefix
• is a kit car built from parts of different makes or models
• is a kit conversion, where a kit body, chassis or monocoque has been added to an existing vehicle, or the other way round
• is a reconstructed classic, as DVLA defines it

The same guidance adds one exception: if a car on that list is taxed as a historic vehicle and has not been modified in the previous 30 years, it is exempt after all.

Large vehicles used commercially have their own rules. The DfT guidance linked below covers them, and it also points to historic vehicle specialists who can help if you are unsure.

How to declare the exemption

GOV.UK says you do not have to apply to stop getting an MOT. Instead, you declare that the car is exempt when you tax it, using the MOT exemption form V112. You still have to tax the car, even if you do not have to pay.

If an engine change or other alteration affects the details on the log book (V5C), there is a legal requirement to tell DVLA. That is a separate duty from the MOT rules.

The MOT exemption is not the historic tax class

People often mix the two up. They are separate rules with separate dates.

• MOT exemption: more than 40 years old and no substantial change in the last 30 years. Nothing to apply for.
• Historic vehicle tax class: GOV.UK says that if a car was built before 1 January 1986, you can stop paying vehicle tax from 1 April 2026. If you do not know when it was built but it was first registered before 8 January 1986, you can also apply. You must apply for this exemption at a Post Office that deals with vehicle tax, and it does not apply to a car used for hire or reward or used commercially for a trade or business.

A car can qualify for one and not the other. For example, a car built and first registered in mid 1986 can be MOT exempt once it is over 40, but it is outside the tax exemption that started on 1 April 2026. Our guide to the historic vehicle tax exemption covers the tax side, and the GOV.UK historic vehicles guide linked in the sources has the current rules.

The car must still be roadworthy

An exempt car is not exempt from the law on vehicle condition. The owner must keep it in a roadworthy state. GOV.UK says you can be fined up to £2,500 and get 3 penalty points for using a vehicle in a dangerous condition.

You can still book a normal MOT for an exempt car, and the DfT guidance says owners may wish to. Some owners do, because it gives an independent check of brakes, steering, lights and corrosion. The result goes into the MOT history like any other test.

What it means when you buy an exempt classic

An exempt car may have no recent MOT history. That is not a warning sign on its own, but it does mean you have less evidence about its condition. A few steps help:

1. Look at the MOT history from before the exemption, if there is one. Read it the way our guide on how to read MOT history explains.
2. Ask whether the owner has had voluntary MOTs since, and for any paperwork.
3. Ask what has been changed and when. An engine swap, a different suspension type or a new bodyshell can mean the exemption does not apply.
4. Check that the log book matches the car, including the engine details.
5. See the car and ask a mechanic who knows older cars to inspect it. A voluntary MOT before you buy is a sensible condition of sale.

Frequently asked questions

Do cars over 40 years old need an MOT?

Not if they were built or first registered more than 40 years ago and have not been substantially changed in the last 30 years. They must still be kept roadworthy.

Do I need to apply for the MOT exemption?

No. You declare the exemption on form V112 when you tax the car. You do need to apply separately if you want the historic vehicle tax class.

Can I still MOT a historic car?

Yes. A voluntary MOT is allowed, and the DfT guidance says owners may wish to have one as an independent safety check.

Is the 40-year MOT exemption the same as free road tax?

No. They are separate rules. The MOT exemption is based on age and changes in the last 30 years. The historic tax class is based on a fixed build or registration date and must be applied for at a Post Office.
