What to expect from your MOT?

Introduction

Whether you've just bought your first car or you've been driving for years, MOT time can feel a little daunting. What does the tester actually look at? How much will it cost? What happens if something goes wrong?

The good news is that the MOT is a straightforward process — and with a little preparation, there's nothing to worry about. Here's everything you need to know, explained plainly and without the jargon.

What is an MOT?

The MOT test is an annual safety check carried out on most cars in the UK to confirm they're safe and roadworthy. It covers everything from your lights and tyres to your brakes and exhaust emissions.

"MOT" stands for Ministry of Transport — the government department that introduced the test back in 1960. Despite the name change of the department over the years, the test has stuck around (and become considerably more thorough).

When does my car need its first MOT?

New cars don't need an MOT until they're three years old. At that point, the test becomes an annual legal requirement.

If you're buying a used car that's less than three years old, you can find the first MOT due date by looking at the third anniversary of the date of first registration — which you'll find on the car's V5C logbook.

Worth knowing: an older car's MOT renewal date can drift from its original registration date, so always check the MOT certificate or use the government's MOT check service to confirm.

How often does my car need an MOT?

Once your car has had its first test, an MOT is required every 12 months. You can have the test carried out up to a month before the due date and the new certificate will still run for 12 months from the original deadline — so you don't lose any time.

If you book significantly earlier than the deadline (say, two months before), the next due date will be calculated from the day of the test rather than the previous deadline, so you could effectively shorten the validity period. A month early is the sweet spot.

What is checked in an MOT?

The MOT tester works through a long checklist. The main areas covered include:

• Lights — headlights, brake lights, indicators, fog lights and dashboard warning lights
• Steering and suspension — checked for wear, looseness or damage
• Brakes — tested for performance and condition
• Tyres and wheels — tread depth, condition and wheel security
• Seatbelts — every belt in the car is inspected and tested
• Bodywork and structure — looking for corrosion or damage that could affect safety
• Exhaust and emissions — both the physical condition and the emissions output
• Windscreen, mirrors and wipers — must be clear and fully functional
• Horn — it needs to work, and produce an appropriate sound
• Fluid leaks — the car must not be leaking hazardous fluids

The tester will carry out both static checks in the workshop and a short road test to assess the car in motion.

What paperwork do I get?

Once the test is completed, you'll receive an MOT certificate showing a pass or fail result.

If your car passes, you may also receive a list of advisories — things the tester has flagged as worth keeping an eye on, but which aren't serious enough to fail the car. Don't ignore these. They often become more expensive problems if left unaddressed.

If your car fails, the certificate will list the specific faults that need to be fixed. Once repairs are made, the car will need to be retested. You don't have to have it retested at the same garage — though many offer a free or reduced-cost retest if they carry out the repairs.

How do I check when my MOT is due?

Your renewal date is printed on your MOT certificate. You can also check it online via the government's MOT check service using your registration number. You'll typically receive a reminder from the DVLA around a month before it's due — but it's worth noting this in your calendar anyway.

What do I need to bring?

All you actually need to bring is the car itself. But before you head off, do a quick check:

• Top up the screenwash — an empty washer bottle is an automatic MOT fail
• Clear the rear seats — the tester needs to be able to access all seatbelts
• Check any obvious warning lights — a permanently lit dashboard warning light is very likely to cause a failure

How long does an MOT take?

Most MOT tests take around an hour. If your car fails and you're having repairs done at the same garage, allow extra time for that work to be completed before the retest.

Can any garage do an MOT?

No — only garages that are registered as official MOT test centres can carry out the test. These centres employ approved testers and use specialist equipment. You can search for your nearest authorised test centre on the government website.

One useful thing to know: all MOT test centres are legally required to let you watch the test being carried out. They must have a viewing area available. You can observe what's being checked — though you're not permitted to speak to the tester while the test is in progress.

How much does an MOT cost?

MOT test centres set their own prices, but there's a legal maximum they're allowed to charge. For a standard car with up to eight seats, the maximum fee is currently £54.85.

Many garages offer combined MOT and service packages at a discount — worth considering if both are due around the same time.

Should I get my car serviced before an MOT?

You don't have to, but it's a sensible idea. A well-maintained car is more likely to pass first time, and if your car breaks down during the road test portion of the MOT, it will fail automatically.

If your annual service and MOT are both coming up, booking them together often saves money and time.

Can I drive my car if it fails?

If your car fails its MOT before the current certificate expires, you're generally still allowed to drive it — as long as the test centre considers it safe to do so. This gives you time to arrange repairs and return for a retest.

If your car fails and the existing MOT has already expired, you can only legally drive it to a pre-booked appointment for repairs or retesting.

Can I drive my car once the MOT expires?

Only if you're driving it to a pre-booked MOT appointment. If you're stopped by the police and don't have a valid MOT, you can receive a fine and penalty points on your licence.

Can I park my car on the road without an MOT?

No. A car without a valid MOT cannot legally be parked on a public road. It must be kept on private land — your driveway, or a garage where it's being repaired. If left on the road, the police have the power to remove and scrap it.

If you're unable to get the car tested for some time, you'll need to apply for a Statutory Off-Road Notification (SORN) from the DVLA.

Does every car need an MOT?

Most cars do, but there are two exceptions:

• Cars under three years old — not yet required to have an annual MOT
• Cars over 40 years old — currently exempt from the MOT requirement

Even if your car is exempt, it's still a good idea to have it inspected annually. Most MOT centres will carry out a safety check on classic cars without issuing a formal certificate.
