Which vehicles are MOT exempt? (classic cars, electric vans and more)

Most vehicles on British roads need an MOT every year once they're three years old. A few don't. The exemptions are narrower than many drivers assume, and being exempt from the test doesn't mean being exempt from keeping the vehicle safe. Exempt doesn't mean unchecked, either: the car must still be roadworthy.

The main MOT exemptions

Historic vehicles: the 40-year rule

The best-known exemption covers classic and historic vehicles. In Great Britain, vehicles built or first registered more than 40 years ago are generally exempt from the MOT, provided they haven't been substantially changed.

The exemption is rolling. Every year, a new batch of vehicles reaches the age limit. If your car was first registered in the summer, it becomes eligible on the same date 40 years later.

What counts as "substantially changed"?

Government guidance looks at changes to key components over the past 30 years, such as:

• the chassis or monocoque bodyshell
• the axles and running gear
• the engine, particularly a change of type or capacity

Original-specification replacement parts are fine. So are changes made to preserve the vehicle or improve safety, such as better brakes or seatbelts, or to keep it usable, such as unleaded fuel conversions. A classic with a modern engine and suspension swapped in is more likely to count as substantially changed and still need an MOT.

How to claim the exemption

The exemption isn't automatic. You declare it:

1. Check the vehicle's age on the V5C logbook.
2. Make sure it meets the "not substantially changed" criteria.
3. Apply to change the tax class to "historic vehicle", which is also exempt from vehicle tax. This is done at a Post Office or by post with the V5C and a declaration form.
4. When you tax the vehicle (even at zero cost), you declare that it's exempt from the MOT.

If you're unsure, the vehicle's owners' club can usually advise.

Older electric goods vehicles

Goods vehicles powered entirely by electricity and registered before 1 March 2015 are exempt from the MOT. This covers vehicles such as older electric vans and milk floats.

This exemption doesn't apply to electric cars, and it doesn't apply to electric vans registered from 1 March 2015 onwards. Those follow the normal MOT schedule. With the growth in electric vans for deliveries, it's an easy rule to get wrong.

Tractors and other specialist vehicles

Agricultural tractors and some other specialist vehicles are exempt from the MOT. Lorries, buses and large trailers don't have an MOT. Instead they go through an annual test with a different set of standards, run by DVSA at authorised testing facilities.

There are also exemptions for vehicles used only on certain islands with no road connection to the mainland. If that applies to you, check the current list on GOV.UK.

Vehicles that aren't exempt (but people think they are)

• Electric and hybrid cars. They need an MOT on exactly the same schedule. The test simply skips the exhaust emissions check on fully electric vehicles.
• Kit cars and replicas. Even if they're styled on a classic, they're judged on when they were built and registered.
• Imported classics. They may qualify for the historic exemption, but only once registered in the UK and if they meet the criteria.
• Vehicles on SORN. A SORN car doesn't need an MOT while it's off the road, but it needs one before it can be taxed and used again.
• Motorcycles and mopeds. They need an MOT from three years old, just like cars.

Exempt doesn't mean unchecked

Every vehicle used on a public road must be roadworthy, whether or not it needs an MOT. The police can stop and inspect an exempt vehicle, and if it's in a dangerous condition the penalties are the same as for any other car: up to £2,500, 3 penalty points and a possible ban.

Insurers also expect the vehicle to be maintained. Specialist classic insurers often ask how you keep the car roadworthy, and some offer better terms if you continue to get it inspected.

Should you get a voluntary MOT?

Many owners of exempt classics still book an MOT every year. A voluntary test:

• gives you an independent safety check by a qualified tester
• creates a record of the vehicle's condition, which can help when selling
• costs no more than a normal MOT, up to £54.85 for a car
• may reassure your insurer

A pass doesn't remove the exemption, and a fail doesn't stop you using an exempt vehicle, but you shouldn't drive anything with dangerous defects.

Buying an MOT-exempt classic

A classic car that hasn't been tested for years can be a lovely thing, or an expensive project in disguise. Without recent MOT results, you lose an independent record of its condition, so you need to work harder at the viewing.

1. Ask when it was last tested. Many owners keep testing voluntarily. If the last MOT was years ago, ask why.
2. Look at the old MOT history. Records from before it became exempt are still visible and show how it was maintained.
3. Check the paperwork. The V5C should show the historic vehicle tax class, and the details should match the car.
4. Ask about modifications. If the car has been substantially changed, it may not qualify for the exemption at all.
5. Get an inspection. A specialist in the make or model is worth paying for, as they know where problems hide.
6. Budget for a voluntary MOT after you buy, so you have a fresh baseline.

Northern Ireland

Northern Ireland has its own vehicle testing system, run by the Driver and Vehicle Agency (DVA). Cars there are first tested at 4 years old, and the rules for exemptions and historic vehicles are set separately. If you live in Northern Ireland or are buying a vehicle registered there, check the current rules on nidirect rather than relying on the Great Britain guidance.

Insurance and exempt vehicles

Check your policy wording before you stop testing an exempt vehicle. Some classic car policies expect a current MOT, and others ask you to confirm how you keep the vehicle roadworthy. Telling your insurer about the exemption, and keeping receipts for regular maintenance, avoids any dispute if you ever need to claim.

Checking a vehicle's status

To see whether a particular vehicle has MOT records, and when it was first registered, run a free MOT check or a reg check. Our report flags vehicles over 40 years old as possibly exempt, and works for vans and motorbikes too. If you're thinking of buying a classic that's claimed to be MOT exempt, check the V5C shows the historic tax class and ask about any modifications.

Summary

Most vehicles need an MOT from three years old. The main exemptions are unmodified vehicles over 40 years old, electric goods vehicles registered before March 2015, and tractors. Electric cars aren't exempt. Whatever the rules, every vehicle on the road must be safe, so many classic owners choose to keep testing anyway.
