Your MOT Questions Answered

For most drivers in the UK, the annual MOT test is an unavoidable part of owning a vehicle.

Although it can feel like a box to tick, it plays an important role in keeping the roads safe. Despite its importance, many drivers are unsure how MOTs work—there are lots of rules and regulations, and it can seem overwhelming.

Questions such as how much a test should cost, and what happens if something goes wrong, are common.

To help, we’ve pulled together answers to the most frequent MOT questions. From how results are recorded to whether warning lights will trigger a fail.

Are MOTs recorded online?

Yes, MOT results are stored digitally in the DVSA’s central database. After your vehicle is tested, the outcome - pass, fail, or advisories- will be logged against your car’s registration number.

You no longer need to rely on a paper certificate to prove your car’s status, as enforcement officers and insurers will check the digital record first.

The online system also lets you look up a car’s MOT history - especially useful when buying or selling.

You can quickly check how a vehicle has performed in previous years, its mileage, and any recurring advisories, giving you a clearer picture of a car’s overall health.

Are MOT test prices the same everywhere?

No. While the DVSA sets a maximum fee of £54.85 for cars, garages are free to charge less. It’s common for garages to offer discounted MOTs in the £30–£40 range to attract customers.

Main dealerships may stick closer to the upper limit (though not always), so it’s worth shopping around. The test itself is standardised - wherever you book, the procedure is exactly the same.

Are MOT failures common?

Yes - and often for reasons that could have been prevented.

Around a third of cars fail their MOT on the first attempt. The most common issues include faulty bulbs, worn tyres, and problems with brakes or suspension.

The positive takeaway is that many of these faults are simple to fix before the test.

Regular car servicing helps pick up items that could cause a fail, giving you time to repair or replace them beforehand.

Even small actions - replacing a bulb, checking tyre tread depth, topping up screen wash - can make a difference.

Will I get fined for no MOT?

Driving without a valid MOT certificate is illegal and penalties can be serious.

You may be fined up to £1,000 and your insurance may no longer be valid.

Automatic number plate recognition (ANPR) cameras help police identify cars on the road with an expired MOT.

The only legal exception is driving directly to or from a pre-booked MOT test. Outside of that, being on the road without a valid certificate puts you at risk.

Will my car pass MOT with a warning light on?

It’s unlikely. Dashboard warning lights form part of the MOT assessment. If your engine management light, airbag light, ABS light, or brake system warning is on, the car will likely fail.

Even if the fault seems minor, testers must record it as a major defect. The safest approach is to have any warning lights investigated and repaired before the MOT.

Should I get an MOT before selling my car?

Yes, it can be a good thing - although it isn’t required.

A current and valid MOT certificate makes selling much easier and reassures potential buyers about the car’s safety and roadworthiness. Vehicles without one are often worth less, attract fewer enquiries, and may appeal only to traders or bargain-hunters.

For private sales, arranging an MOT in advance can help secure a quicker sale and even a better price.

Should I repair my car before MOT?

If you already know of faults, repairing them before the test is strongly recommended. Minor issues like worn tyres, faulty wipers, or a broken headlight are straightforward fixes and can prevent an automatic failure.

More significant mechanical issues should also be addressed. Not just for the sake of the MOT, but for the safety and reliability of your car.

Can I take my car for MOT early?

Yes. You can book an MOT up to one month (minus a day) before the expiry date while keeping the same renewal date for the following year.

For example, if your MOT is due on 20 October, you can book from 21 September and still keep 20 October as the renewal date.

Booking early gives you added flexibility if repairs are required. It helps to avoid the stress of last-minute appointments.

MOT Q&A Summary

The MOT test is a legal formality that safeguards drivers, passengers, and everyone else on the road. Understanding how the system works makes the process far less stressful:

• Prepare in advance
• Fix known faults
• Stay informed about your responsibilities as a car owner

This will help to improve your chances of passing first time, and avoid unnecessary costs. Or, delays, and penalties.

Whether you’re booking an MOT soon or getting ready to sell your car, being proactive will always work in your favour.
