Your Car's First MOT: When It's Due and What to Check

When is your car's first MOT test due? Learn the three-year rule, why the date is easy to miss and the checks that help a newer car pass.
In Great Britain, a car's first MOT test is due by the third anniversary of its first registration. Because there is no previous certificate to remind you, this is the date drivers miss most often, so check it now and book within the month before it falls. A three-year-old car is usually in good shape, but low mileage and a lack of attention can still cause a fail on simple items.
This guide explains how to work out the date, what tends to catch out newer cars and how to make sure you never miss a renewal again.
When is the first MOT due?
The rules depend on where the car is registered and what it is used for:
- Cars in Great Britain: by the third anniversary of first registration.
- Some vehicles, such as taxis: at one year, and then every year.
- Northern Ireland: different rules apply, with the first test for cars at four years.
After the first test, an MOT is needed every year. You can have it up to a month (minus a day) before the due date and still keep the same renewal date, so there is no benefit in waiting until the last moment.
Why the date is so easy to miss
Every later MOT comes with a certificate that shows the next expiry date. The first one does not, because there is nothing to renew. Many drivers also buy a nearly new car and assume the seller or dealer will remind them. If you are not sure, the free GOV.UK "check MOT history" service shows when the first test is due once you enter the registration. Our guide on checking your MOT due date covers the other places to look.
Driving after the due date without a valid MOT can lead to a fine of up to £1,000, unless you are driving to a pre-booked test or to a garage for repairs needed to pass.
Common first MOT test problems on newer cars
A newer car is unlikely to fail on corrosion or worn suspension, but small items still matter. Cars that cover few miles can also develop problems from standing still. The table below shows what to look at.
| Item | Why it can catch out a newer car | Quick check at home |
|---|---|---|
| Tyres | Original tyres may be worn after three years, or cracked from standing | Check tread depth and look for cuts, bulges and cracking on the sidewalls |
| Wiper blades | Rubber hardens with age and sunlight, even with little use | Run the wipers and look for smears or missed areas |
| Bulbs | Brake and number plate bulbs fail without the driver noticing | Walk round the car with someone pressing the brake and switching on each light |
| Warning lights | Faults such as an engine or tyre pressure warning may have been ignored | Start the car and make sure every light goes out after the self-check |
| Brakes | Discs can corrode on cars that sit still for long periods | Listen for grinding and check the car stops straight |
| Screenwash and windscreen | An empty washer bottle or a chip in the driver's view can cause a fail | Top up the bottle and look for chips in front of the driver |
Tyres deserve a closer look
The legal minimum tread is 1.6mm across the central three-quarters of the tread, around the whole circumference. Many experts recommend replacing tyres nearer 3mm. Front tyres on a three-year-old car can be close to the limit, especially on a front-wheel-drive car used in town. See our guide to MOT tyre rules.
Do not ignore a warning light
An engine management light that stays on can mean a fail. If one has appeared, have it checked before the test. Our guide to the engine management light before an MOT explains why.

Pair the first MOT with the third service
The first MOT often falls close to the car's third annual service. Doing both together means one trip, and any worn parts found during the service can be fixed before the test. If the car is still under the manufacturer's warranty, you do not have to go back to a dealer for the service. Under UK block exemption rules, an independent garage can service a car in warranty, as long as it follows the manufacturer's schedule and uses parts of matching quality.
Low-mileage cars still need servicing on time, because oil and brake fluid age even when the car is parked. Read more about low mileage car servicing.
With Hon Car Service, the MOT is discounted when booked with a service, carried out at an approved MOT test centre and includes free collection and return. It is never done at your home or office.

Frequently asked questions
Does a new car need an MOT test in its first three years?
Not in Great Britain, unless it is a vehicle such as a taxi that needs one at one year. The first test is due by the third anniversary of first registration.
Can I have the first MOT early?
Yes. You can have it up to a month (minus a day) before the due date and keep the same renewal date.
Is a three-year-old car likely to fail?
It is less likely than an older car, but it can still fail on tyres, bulbs, wipers or warning lights. A few simple checks reduce the risk.
What happens if my first MOT test finds advisories?
Advisories and minor defects still allow a pass. They are listed on the result so you can plan the work before they become a problem.
