MOT exempt vehicles fall into a short list of categories: some historic vehicles, tractors, certain electric goods vehicles and vehicles that follow a different test regime such as lorries, buses and trailers. The best known exemption is the rolling 40-year rule for older cars and motorcycles, and it is also the most misunderstood. Whether a classic qualifies depends on its age and on whether it has been substantially changed. This guide explains each category, the paperwork for declaring an exemption, how an exempt vehicle appears in a vehicle checker, and why exempt does not mean you can ignore the condition of the vehicle.
Want to see whether a specific vehicle has MOT records at all? Run its registration through our free MOT check. A vehicle with no test record may be exempt, may be brand new, or may have a data issue; the sections below explain how to tell.
Quick answers
- How old must a car be to be exempt? Built or first registered more than 40 years ago, and not substantially changed. The exemption starts on the 40th anniversary.
- Is an old car automatically exempt? No. A substantial change to a main component such as the chassis, body, axles or engine can remove the exemption.
- Do I have to say so? Yes. You declare the exemption when you tax the vehicle, using form V112 for cars. You still have to tax it, even if nothing is payable.
- Which other vehicles are exempt? Tractors, and electric goods vehicles registered before 1 March 2015. Lorries, buses and trailers have an annual test instead.
- Can I still get an MOT? Yes. A voluntary test is allowed, and an exempt vehicle must still be roadworthy.

The 40-year rolling rule for historic vehicles
A vehicle does not need an MOT if it was built or first registered more than 40 years ago and has not had substantial changes. The 40-year window moves forward every year, which is why people call it rolling. Each year, vehicles that cross the 40-year line join the exempt group, so a car that needed an MOT last year may not need one this year. GOV.UK explains that the exemption starts on the 40th anniversary of registration or manufacture. Its own example is a car registered on 31 May 1978, which needs no MOT from 31 May 2018.
Before May 2018 the rule was different: only vehicles built before 1960 were exempt. The change in 2018 brought in the rolling 40-year rule for cars, vans, motorcycles and other light passenger vehicles, and it also removed the fixed 1960 date for those vehicles. Two points are easy to miss:
- The test is “built or first registered” more than 40 years ago. Either date can qualify the vehicle, which helps when the build date and the registration date are different.
- Age alone is not enough. The vehicle must also be free of substantial changes, covered next.
What counts as a substantial change
A substantial change is a modification that alters how the vehicle works, not a cosmetic or like-for-like repair. The government examples include replacing the chassis, the body, the axles or the engine to change how the vehicle works. A restoration that keeps the original type of components is different from a conversion that fundamentally changes the vehicle.
The official criteria published on GOV.UK go into more detail. They say an alteration is substantial if the technical characteristics of a main component have changed in the previous 30 years, unless it counts as an acceptable change. For cars, the main components are the chassis or frame, the monocoque bodyshell, the axles and running gear, and the engine.
| Main component | What is not substantial | What can be substantial |
|---|---|---|
| Chassis or frame | Like-for-like replacement in the original pattern | A different type of chassis or frame |
| Monocoque bodyshell | Replacement in the original pattern, including sub-frames | A different bodyshell |
| Axles and running gear | Changes that keep the original type of suspension and steering | Changing the type or method of suspension or steering |
| Engine | Alternative cubic capacities of the same basic engine, or alternative original-equipment engines | An engine with a different number of cylinders, which is typically but not always non-original |
The criteria also describe changes that are acceptable and do not count as substantial. These include changes made to preserve a vehicle when original-type parts are no longer reasonably available, changes of a type that were made during production or within 10 years of its end, axle or running-gear changes made to improve efficiency, safety or environmental performance, and changes made while the vehicle was used commercially if you can prove when they were made.
The practical consequences:
- A vehicle that has been substantially changed loses the historic exemption even if it is much older than 40 years, and it needs an MOT as normal.
- Routine servicing, replacing worn parts with equivalents and period-correct restoration are generally different from the changes the rule has in mind. If you are unsure, read the official guidance before you declare an exemption. GOV.UK states that if you cannot confirm that no substantial change has been made, you must not claim the exemption.
- The decision is yours as the keeper, so keep records of what was changed and when.
- You must tell DVLA about changes that affect the V5C log book, such as an engine replacement.
If a vehicle you are about to buy is sold as exempt, ask what work has been done. Evidence of a swapped chassis or engine type could mean the exemption does not apply.
Vehicles that may not qualify even when old
The GOV.UK criteria say that some types of vehicle need an MOT even when they are more than 40 years old, or need a closer look at whether they qualify. These include large vehicles used commercially, vehicles with a “Q” registration prefix, kit cars built from a mixture of makes or models, kit conversions and reconstructed classics as defined by DVLA. The criteria set out how some of these can still qualify, so if your vehicle falls into one of these groups, read the criteria carefully before you decide, and do not assume the exemption applies.
For large vehicles, the criteria are more detailed. Large goods vehicles over 3.5 tonnes and buses with eight or more passenger seats used commercially need a test if they have been substantially changed in the last 30 years. The declaration for those is on form V112G. A pre-1960 vehicle in these groups may be treated differently from a younger one. If you own a large vehicle, use the official criteria and the annual test guidance, because the rules are specialist.
Other vehicles that do not need an MOT
| Category | MOT position |
|---|---|
| Historic vehicles (built or first registered more than 40 years ago, no substantial changes) | Exempt |
| Tractors | Exempt |
| Electric goods vehicles registered before 1 March 2015 | Exempt |
| Lorries, buses and trailers | Need an annual test instead of an MOT |
| Vehicles that have not yet reached the age at which a first MOT is due | No MOT needed yet |
Do not confuse “exempt from the MOT” with “exempt from testing”. Lorries, buses and trailers are tested every year under a different regime run by DVSA, so there is still a roadworthiness check, just not the one cars and motorcycles use. Electric goods vehicles are only exempt if they were registered before 1 March 2015; a later registration needs an MOT like any other goods vehicle. GOV.UK also refers to other vehicle types listed on the MOT exemption form (V112), so check that list if your vehicle is unusual. The full and current list sits in the official guidance at GOV.UK.
New vehicles are a separate case. A car registered less than three years ago has no MOT yet, because the first test is due by the third anniversary of registration. That is a matter of timing, not an exemption, and our first MOT guide explains the dates. Some vehicle types need their first MOT at one year, so check the category of your vehicle.
The vehicle tax exemption is a separate rule
The historic vehicle tax exemption uses a different date from the MOT exemption. GOV.UK says that vehicles made before 1 January 1986 are exempt from vehicle tax, and a vehicle first registered before 8 January 1986 can qualify if the build date is unknown. That date is stated as a fixed cut-off, whereas the MOT rule rolls forward each year with the vehicle’s own 40th anniversary. The result is that a vehicle can be MOT exempt but still need to be taxed, or tax exempt but still need an MOT. GOV.UK also says you must tax your vehicle even if you do not have to pay.
For example, a vehicle might pass the 40-year MOT test this year yet be built after the tax cut-off, so it is exempt from the MOT but not from tax. Always treat the two exemptions as two separate decisions, and check the dates on GOV.UK because they are published and updated by the government. Our car tax check shows the current tax status from DVLA data, and a vehicle declared off the road shows up in the SORN check.
How to declare that your vehicle is exempt
An MOT exemption is not automatic on paper. GOV.UK says you must declare the exemption when you apply to tax the vehicle. The declaration is on form V112 for cars and form V112G for large vehicles. The form is where you state that the vehicle qualifies for the exemption, and you make the declaration as part of taxing it. The route and form details can change, so follow the current instructions at GOV.UK rather than relying on a copy elsewhere.
Keep in mind that the declaration is your statement that the vehicle meets the rules. If it later turns out to have been substantially changed, the exemption claim would be wrong, so be honest and keep your records. A good file includes photographs of the vehicle over time, receipts for major parts, the V5C log book and any correspondence with a club or a specialist who has confirmed the vehicle’s originality.
- Work out whether the vehicle was built or first registered more than 40 years ago.
- Review the main components against the official criteria and your records.
- If you can confirm that there has been no substantial change in the previous 30 years, make the declaration when you tax the vehicle.
- If you cannot confirm it, do not claim the exemption. Book an MOT.
- Tell DVLA about changes that affect the V5C, such as an engine replacement.
You can still take a voluntary MOT
Exempt means you are not required to have an MOT. It does not stop you booking one. GOV.UK suggests you may choose to take one voluntarily, and plenty of owners of older vehicles do so, for three reasons:
- It gives an independent check of brakes, steering, lights, tyres and structure.
- Clubs and event organisers sometimes like to see a recent test, so ask yours what it expects.
- A recent pass helps when selling, because buyers can verify it online.
A voluntary test is recorded in the same DVSA history as any other, so it becomes part of the permanent record. Because of that, a failed voluntary test also appears. Consider that before booking if you plan to sell soon, and if the car fails, fix the faults and retest. Ask the garage for the price before booking; for a car the standard maximum MOT fee is £54.85 and garages may charge less (see MOT cost). The grades a voluntary test can produce are explained in MOT defect categories.
Exempt does not mean roadworthy
An exempt vehicle must still be roadworthy. GOV.UK states that your vehicle must be roadworthy whether it is exempt or not. The keeper is responsible for the condition of the vehicle, and an unsafe vehicle can be stopped and prosecuted even though it has no MOT requirement. The rules on dangerous vehicles do not depend on an MOT: a vehicle in a dangerous condition is illegal to drive on the road. Driving with a dangerous defect can bring a fine of up to £2,500, a driving ban and 3 penalty points.
Sensible owners of exempt vehicles carry out their own regular checks on the parts an MOT would cover: brakes, tyres, steering, lights, mirrors, seat belts where fitted, exhaust and structure. If you do not trust your own inspection, a voluntary test costs relatively little. Our MOT test checklist lists the areas a tester covers, and how to prepare for an MOT sets out a home check that works equally well for a classic.
How an exempt vehicle looks in a vehicle checker
Our checker pulls MOT data from the DVSA MOT history service and vehicle data from the DVLA Vehicle Enquiry Service. For an exempt vehicle, expect one or more of these:
- No MOT history at all. If the vehicle has never been tested, there is nothing to list.
- An MOT status of “No details held by DVLA” or “No results returned”, both of which are normal for a vehicle without MOT records.
- Old tests followed by a long silence. A vehicle that was tested every year until it qualified for the exemption, then stopped, has a history that simply ends.
- Tax status and tax due date still shown, because tax is recorded separately.
No MOT data does not prove exemption. The same blank result appears for a vehicle that is new, a vehicle whose MOT is overdue, or one that is Northern Ireland registered (MOTs there are run by DVA, a separate service). If you are viewing a vehicle that should need an MOT, treat the missing data as a question to ask the seller. Our guide to reading an MOT history covers what each status means.
What our free tools show, and what they cannot
| The free tools show | The free tools cannot show |
|---|---|
| Every recorded MOT in England, Scotland and Wales since 2005, including voluntary tests | Whether a vehicle has been declared exempt. The declaration is made to DVLA with the tax application |
| The MOT status and expiry date held by DVLA, and the tax status and due date | Whether any substantial change has been made, or what work was done on the chassis, body, axles or engine |
| The vehicle’s make, colour, fuel type, engine size, year of manufacture and month of first registration where DVLA holds them | The keeper’s name or address, or finance, stolen or write-off data |
| The first used date, registration date and manufacture date where DVSA holds them | Northern Ireland tests, held separately by DVA |
The historical MOT check is useful for older vehicles because it concentrates on the full run of past tests. The mileage check plots recorded odometer readings, which can show how much a classic has been used between tests and whether the pattern looks plausible. Remember that a mileage flag is an indicator from our own analysis of recorded readings and not proof of anything. Find out more in how we get our data.
Buying an exempt vehicle: what to check
- Work out the age from the build date or first registration date, using the V5C log book and the vehicle record.
- Ask what work has been done to the chassis, body, axles and engine, and ask for receipts.
- Check the tax position separately, using the tax-specific date.
- Look at any old MOT records for mileage, repeated corrosion advisories and past failures; see MOT advisories explained.
- Consider paying for an independent inspection, since an exempt vehicle has no recent test to rely on.
- Run the registration through our vehicle check. The £3.99 Full Vehicle Report adds a PDF timeline and mileage analysis. It does not include finance, stolen or write-off data, so use a licensed provider if you need those.
- Compare what the advert says with the record using the seller claim checker.
- Follow the wider steps in the used car checklist.
Worked examples
The examples below are invented to show how the rules apply. They are not records of real vehicles.
Illustrative example 1: a well-preserved original
A saloon was first registered in 1981. It has its original chassis, body, axles and engine, and the owner has kept receipts for like-for-like repairs. It is more than 40 years old and has had no substantial change in the last 30 years, so the owner can declare the exemption when taxing the car. The owner chooses to take a voluntary MOT every year for peace of mind, and the passes appear in the online history.
Illustrative example 2: an old car with a different engine
A sports car was first registered in 1979. Twelve years ago the owner fitted an engine with a different number of cylinders from a later model. The criteria say a change of cylinder count is typically but not always non-original, so the owner cannot be sure the change is acceptable. If the owner cannot confirm that no substantial change has been made, the exemption should not be claimed, and the car needs an MOT. A specialist opinion or the club may help to decide.
Illustrative example 3: exempt for MOT, not for tax
A hatchback was built in 1984 and first registered in 1985. After the 40th anniversary it no longer needs an MOT, provided it is unchanged. It was built before 1 January 1986, which GOV.UK gives as the tax cut-off, so it can also claim the tax exemption. The owner still has to go through the process of taxing the vehicle, and declares the MOT exemption at the same time. A second car built in 1988 would be a different case: its MOT exemption would arrive later, and it would not meet the tax cut-off at all.
Illustrative example 4: a tractor and a van
A tractor is exempt from the MOT. An electric van registered in 2016 is not, because only electric goods vehicles registered before 1 March 2015 are exempt. The van follows the ordinary MOT cycle for a goods vehicle, and its owner can check the date using the van MOT check.
Common mistakes with MOT exemption
- Assuming every old car is exempt. The 40-year rule needs a qualifying age and no substantial changes.
- Mixing up the tax and MOT dates. They are not the same date and they work differently.
- Forgetting the declaration when taxing the vehicle.
- Believing exempt vehicles can be unsafe. Roadworthiness still applies.
- Treating missing MOT data as proof of exemption when the real reason is an overdue test.
- Claiming the exemption without evidence of what has been changed over the last 30 years.
- Forgetting to tell DVLA about changes that affect the log book, such as a new engine.
- Assuming that electric vans are all exempt. Only goods vehicles registered before 1 March 2015 qualify.
If an MOT is needed and you have let it lapse, read driving without an MOT for the legal position. Driving without a valid MOT can bring a fine of up to £1,000, with exceptions for driving to or from a repair or to a pre-arranged test.
Edge cases
Motorcycles and three-wheelers
The 2018 change applies to motorcycles as well as cars, vans and other light passenger vehicles, though the official criteria for the main components of motorcycles may be set out separately. Check GOV.UK for the current position, and see MOT test classes and the motorcycle MOT check.
Vehicles in Northern Ireland
Northern Ireland has its own vehicle testing scheme run by DVA, and its rules are not the same as those in Great Britain. If a vehicle is registered there, read MOT in Northern Ireland.
Vehicles that become non-exempt
If you make a substantial change to an exempt vehicle, it needs an MOT. Plan the change with that in mind, and keep records showing when it was made.
Vehicles kept off the road
A vehicle that is declared off the road with a SORN does not need to be taxed while the declaration is in place. This is a separate matter from MOT exemption. The SORN check shows the status.
Exempt vehicle in a clean air or low emission zone
An MOT exemption does not exempt a vehicle from emissions zones. If you drive an older vehicle into a charging area, check the vehicle with the ULEZ checker and the clean air zone checker, and confirm the position on the official TfL or council page before you travel.
This guide summarises the official position but is general information, not legal advice. Exemption rules are set by the government and can change; always confirm on GOV.UK. MOT Check Now is independent and is not part of DVLA, DVSA or GOV.UK.
Next steps
- Look up the vehicle on the free MOT check and note its status.
- Check the build and registration dates against the 40-year rule.
- Review the main components against the official criteria.
- Declare the exemption when taxing, or book an MOT if you cannot confirm it.
- Read the MOT history for older tests if you are buying.
- If the vehicle does need an MOT, set the free MOT reminder and read how early you can get an MOT.
