In short
- A car needs its first MOT by the third anniversary of its registration, not of the day it was bought[1].
- In Northern Ireland, cars are tested from four years old[8].
- You can take an MOT up to a month (minus a day) early and keep the same renewal date[1].
- A car over 40 years old needs no MOT only if it has had no substantial change in the last 30 years[4]. The exemption has to be declared when the car is taxed.
- A car under three years old usually has no MOT history yet. An older car with none needs an explanation.

The MOT is the yearly check that a car is safe and fit for the road. In England, Scotland and Wales, a car needs its first one by the third anniversary of its registration[1]. Think of it as the car’s third birthday, counted from the day it was first registered.
That isn’t the day it was bought. A second-hand car that is two years old still has its first MOT due on its third birthday. After that, an MOT lasts one year.
The law covers a car first registered at least three years earlier. It also covers a car made at least three years earlier and used on the road before registration, such as an import[7].
A few types of vehicle are tested sooner. Licensed taxis (not private hire cars), ambulances and passenger vehicles with nine or more seats need their first MOT at one year old[2].
Find the registration date
Ask the seller for the date the car was first registered. The V5C logbook (the registration document) records it. The date the seller bought the car doesn’t count.
Add three years
The first MOT is due by the third anniversary of that date[1]. A car first registered on 3 March 2023, for example, needs its first MOT by 3 March 2026.
Book the test
You can go up to a month (minus a day) early without losing time. The next section explains how that works.
Check the MOT status once the car has one
GOV.UK’s free MOT status check shows when a car’s MOT ends[10].
Missing the date can be costly. Driving without a valid MOT can bring a fine of up to £1,000 (as of 10 October 2026)[1]. Our guide to driving without an MOT explains the two exceptions.
You can take an MOT up to a month (minus a day) before it runs out and keep the same renewal date[1]. Go earlier than that and the next MOT runs for a year, minus a day, from the test date.
| If the MOT runs out on 15 May | The next MOT then runs out on |
|---|---|
| A test on 16 April or later | 15 May the next year |
| A test on 14 April (earlier than 16 April) | 13 April the next year |
GOV.UK’s own example[1].
So going too early only makes the next MOT shorter. That rule is written for renewals. For a first MOT, ask the test centre which expiry date your certificate will carry. A first MOT has the same top fee as later ones (see how much an MOT costs).
Some older cars need no MOT. A car is exempt if it was built or first registered more than 40 years ago. It must also have had no substantial change in the last 30 years[4]. Both parts have to be true.
MOT exempt, if all of these are true
- It was built or first registered more than 40 years ago
- It has had no substantial change in the last 30 years
- The keeper declares the exemption when taxing it
Still needs an MOT, even over 40
- A car with a substantial change in the last 30 years
- A car with a Q-prefix registration
- A kit car built from parts of different makes or models
- A kit conversion
- A reconstructed classic, as defined by DVLA (the agency that registers cars)
- A large vehicle used commercially[4]
The keeper is the person the car is registered to. They declare the exemption when they tax the car, using form V112[5]. The car must still be taxed, even if there is nothing to pay[4].
The criteria allow one narrow exception to that list. A vehicle taxed as a historic vehicle that has not been modified in the last 30 years is exempt[4].
So what counts as a substantial change? It is a change to the make-up of a main part in the last 30 years, unless it is an acceptable change[4]. For cars, the main parts are these.
| Main part | What the rules say |
|---|---|
| Chassis or frame | Replacing it with one of the same pattern as the original is not a substantial change. |
| Body shell (a monocoque, with the body and frame in one piece) | Replacing it with one of the same pattern, sub-frames included, is not a substantial change. |
| Axles, suspension and steering | Changing the type or method of suspension or steering is a substantial change. |
| Engine | Another size of the same basic engine, or another original-equipment engine, is not a substantial change. |
Department for Transport criteria, last updated 19 May 2026[4].
Some changes are acceptable. Examples are changes made because original-type parts are no longer reasonably available. Others are changes of a kind made while that model was in production or in the ten years after[4].
GOV.UK names a few other kinds of vehicle that need no MOT. They are tractors, goods vehicles powered by electricity that were registered before 1 March 2015, and some historic vehicles[3]. The V112 form lists every exempt type.
For a used car, the historic rule is the one you are most likely to meet. A classic that looks exempt may not be, so ask how the seller knows.
Myth
The three years run from the day you bought the car.
What's true
They run from the day the car was first registered[1].
Myth
Every car over 40 years old is exempt automatically.
What's true
It must also have had no substantial change in 30 years. The keeper has to declare the exemption when taxing the car.
Myth
A car that pays no road tax doesn’t need an MOT.
What's true
The two exemptions use different tests, and a car can qualify for one and not the other.
Myth
An exempt car doesn’t have to be safe.
What's true
It must still be roadworthy, exempt or not.
Here is how the tax and MOT rules can differ. From 1 April 2026, the tax exemption covers vehicles built before 1 January 1986. If the build date isn’t known, it covers those first registered before 8 January 1986[6]. The MOT rule uses a rolling 40 years.
Take a car built in March 1986. As of 10 October 2026 it is more than 40 years old, so it can be MOT exempt if it is unchanged. It was built after 1 January 1986, so it is not tax exempt.
Check the car’s age first. A car under three years old usually has no MOT history yet. There is nothing to read on the record, so ask to see the service record instead.
An older car with no MOT history is different. It needs an explanation. It may be exempt, may have been tested in Northern Ireland before 2017, or may have been kept off the road. The record can’t show which, so ask the seller. Our guide to gaps in MOT history covers the common reasons.

These figures are for cars that took their first-ever MOT in 2025, having first been used in 2021 or 2022. Across cars of all fuels, about 1 in 9 first MOTs (11.2%) failed (MOT Wise analysis of DVSA MOT results, 2025).
- Diesel
- 15.5%
- Electric
- 13.4%
- All fuels
- 11.2%
- Petrol
- 10.2%
- Hybrid
- 9.7%
Cars only. Each car’s first-ever MOT, taken in 2025: failed first MOTs as a share of all first MOTs. Diesel is based on 157,208 first MOTs, the fewest of the four fuels. Hybrid covers full, mild and plug-in hybrids together. MOT Wise analysis of DVSA MOT results, 2025.
By our count, diesel cars failed about 1 in 7 first MOTs (15.5%), against about 1 in 10 first MOTs (10.2%) for petrol. The data can’t say why. The groups hold different models, and the cars have done different miles. A fail rate describes a group of cars, not the car in front of you.
Fail rates differ a lot by age. Our guide to fail rates by age shows how.
Common questions
Does a new car need an MOT?
Not at first. In England, Scotland and Wales, a car needs its first MOT by the third anniversary of its registration. In Northern Ireland, cars are tested from four years old.
Do the three years start from the day I get the car?
No. They run from the day the car was first registered. A second-hand car can need its first MOT soon after you take it on, so check the registration date.
How early can I book a first MOT?
You can take an MOT up to a month (minus a day) before it is due and keep the same renewal date. For a first MOT, ask the test centre which expiry date your certificate will carry.
Does a car over 40 years old need an MOT?
Not always. It is exempt only if it was built or first registered over 40 years ago. It must also have had no substantial change in the last 30 years. The keeper has to declare the exemption when taxing the car.
Is a tax-free classic car also MOT exempt?
Not always. The tax exemption and the MOT exemption use different tests, so a car can qualify for one and not the other.
