What Is Checked in an MOT? The Full UK MOT Checklist Explained

An MOT checks that your car meets the minimum legal standards for road safety and exhaust emissions. The tester inspects the lights, brakes, tyres, steering and suspension, seatbelts, the windscreen and wipers, the exhaust and emissions, the horn, mirrors, number plates and the body and structure of the car. Crucially, it does not check the condition of the engine, clutch or gearbox (gov.uk). It is a safety check, not a service.

That is the headline, and if you have just bought your first car it is the bit worth remembering. But an MOT catches a lot of people out the first time – partly because they expect it to cover more than it does, and partly because nobody explains the difference between a fail, a “major”, a “dangerous” and an “advisory”. Below I will walk you through the full checklist the way a tester works round the car, the items that fail the most cars, and exactly what happens after the test. This is car-ownership admin that your driving lessons never cover, yet it is your legal responsibility the moment the keys are yours.

What is an MOT and when does your car need one?

An MOT is an annual test that confirms your car is roadworthy and meets legal safety and emissions standards. It is run by the DVSA through around 23,000 approved test centres, and it is a legal requirement to keep most cars on the road.

Here is the timing, straight from gov.uk:

• A new car needs its first MOT by the third anniversary of its registration date.
• After that, it needs an MOT every year, on or before the anniversary of the last one.

You can get the test done up to a month (minus a day) before your current certificate runs out and keep the same renewal date, which is the trick to never letting it lapse. That matters if you plan to sit your practical in your own car, because a valid MOT is one of the DVSA vehicle requirements for the driving test. Driving without a valid MOT can land you a fine of up to 1,000 pounds (gov.uk), and the date is checked automatically by police ANPR cameras, so it is not something you can quietly forget.

One question I get asked a lot: an MOT is not the same as a service. A service looks after the mechanical health of the car – oil, filters, wear – and is optional. The MOT is a legal safety check with a pass or fail. You need the MOT; the service is how you avoid failing it.

What is checked in an MOT? The full checklist

The tester works methodically around the car, inside and out, against the DVSA inspection manual. Here is the full list of what gets checked, grouped the way it actually happens, so nothing surprises you.

Area	What the tester checks
Lights and signals	Headlights, sidelights, brake lights, indicators, hazards, fog lights, number-plate lights and reflectors – all working, secure, correct colour and aim
Steering and suspension	Steering operation, condition of joints and bushes, shock absorbers, wear, damage and corrosion
Brakes	Efficiency, condition and balance of the service brake and handbrake (measured on a rolling brake tester), plus ABS warning lights
Tyres and wheels	Size and type, general condition, and a tread depth of at least 1.6mm across the central three-quarters (gov.uk); wheels checked for damage
Seatbelts and seats	All belts present, secure and working, buckles latch and release, driver’s seat adjusts and locks
Body and structure	Chassis and body checked for excessive corrosion, damage or sharp edges that could injure someone
Exhaust and emissions	Exhaust secure and not leaking; emissions measured against the limit for your car’s age and fuel type
Windscreen and view of the road	Chips or cracks in the driver’s line of sight, plus wipers and washers that clear the screen
Registration plates	Present, secure, legible and the correct spacing and font
Horn, mirrors and more	Horn works, required mirrors present and secure, fuel system leak-free, and the speedometer and warning lights are checked

A few extras have crept in over the years worth flagging. Since 2018 the MOT also looks at whether dashboard warning lights for things like airbags, ABS and the tyre-pressure monitoring system are illuminated – a lit airbag light alone can fail the car. On diesels with a diesel particulate filter (DPF), visible smoke or a tampered filter is an automatic failure. And the fluids the tester needs to do the job, such as brake fluid and screen wash, are checked as part of the relevant items.

What does an MOT not check?

An MOT does not check the mechanical condition of the engine, clutch or gearbox (gov.uk). It is the single biggest misunderstanding new owners have, so it is worth being clear about.

Passing an MOT tells you the car was roadworthy on the day, not that it is mechanically healthy or reliable. The test will not tell you the clutch is on its way out, the gearbox is whining, the engine is burning oil or the timing belt is overdue. It also does not cover the general working of the air conditioning, the sat nav or the infotainment. That is what a service and a proper pre-purchase inspection are for. If you are buying a used car, a fresh MOT is reassuring but it is not a clean bill of health – always factor in a service history too.

What can fail you on an MOT?

The most common MOT failures are simple, cheap-to-fix items: lights, tyres, brakes, and the driver’s view of the road. Lighting and signalling faults are consistently the number-one reason cars fail (DVSA), often just a blown bulb that would have cost a couple of pounds to replace before the test.

Here are the usual culprits, roughly in the order they trip cars up:

• Lights – a blown headlight, brake light or indicator bulb, or a hazy, misaligned headlamp.
• Tyres – below the 1.6mm legal minimum, or with cuts, bulges or exposed cords.
• Brakes – worn pads or discs, an imbalance side to side, or a weak handbrake.
• Driver’s view of the road – a crack or chip in the wiper-swept zone directly in front of the driver, or worn wiper blades that smear.
• Suspension – worn shock absorbers, broken springs or perished bushes.
• Emissions – readings over the limit, often a symptom of a deeper fault on older cars.
• Number plate – cracked, faded, dirty or the wrong font or spacing.

The good news for a nervous first-timer: a lot of these you can check or fix yourself in ten minutes on the driveway – walk round the car with the lights on, top up the screen wash, clean the plates, and do the 20p tread test on each tyre. It is the same “get the basics right” mindset that helps you build confidence behind the wheel once you have passed.

Fail, major, dangerous or advisory: what the result actually means

Since 2018 every MOT defect is graded, and the grade decides whether you pass and whether you can drive the car away. There are four categories, and getting them straight saves a lot of worry.

Category	Pass or fail?	What it means
Dangerous	Fail	A direct and immediate risk to safety. You must not drive the car until it is fixed
Major	Fail	Could affect safety or the environment. Must be repaired and the car retested
Minor	Pass	A small fault noted on the certificate; repair it as soon as you can
Advisory	Pass	Something starting to wear that will likely need attention before long – monitor it

So a car passes with minor or advisory items but fails on anything graded major or dangerous (gov.uk). An advisory is not a failure and does not stop you driving – think of it as the tester’s heads-up, for example “brake pads wearing thin” or “tyre close to the legal limit”. It is genuinely useful: it tells you what to budget for next.

The category that carries real teeth is dangerous. Drive a car that has failed its MOT because of a dangerous defect and you can be fined up to 2,500 pounds, banned from driving and given 3 penalty points (gov.uk). For a new driver that 3-point risk is especially serious, which brings us to the point most guides skip.

Why a failed MOT matters more for a brand-new driver

If you passed your test within the last two years, three penalty points is not just a fine – it can cost you your licence. Under the Road Traffic (New Drivers) Act 1995, if you build up 6 or more penalty points within two years of passing, your licence is revoked and you go back to a provisional, retaking both the theory and practical tests (gov.uk).

That is why the “dangerous defect” penalty deserves respect. Getting caught driving a car with a dangerous MOT failure puts 3 points on a new licence in one go – halfway to losing it. The lesson is simple: if your car fails on a dangerous fault, do not drive it. Get it recovered or repaired at the test centre. It is not worth the risk to a licence you have only just earned.

After the test: passing, failing and driving away

If your car passes, the result is recorded on the DVSA’s central database automatically – the paper certificate is a backup, not proof in itself. Anyone can check a car’s MOT status and history free on gov.uk using the registration, which is a handy tool when you are buying used.

If it fails, what you can do next depends on your existing certificate:

• If your previous MOT is still valid and no dangerous faults were listed, you can drive the car away to get it repaired.
• If your previous MOT has run out, or the car has a dangerous fault, you cannot drive it on the road at all – except to a pre-booked repair or retest appointment (gov.uk).

Get the faults fixed and take the car back for a retest. If you leave it at the same centre and it is repaired within ten working days, the partial retest is often free or reduced. Cutting it fine on your MOT date is the thing to avoid: leave yourself a week or two of headroom so a failure does not leave you off the road.

How much does an MOT cost?

The maximum an MOT test centre can charge for a standard car (Class 4) is 54.85 pounds, set by the government, with no VAT on top (gov.uk). A motorcycle is capped at 29.65 pounds. Many garages charge less than the maximum to win your business, and some offer a free retest, so it pays to shop around.

Remember what the fee does and does not include. It covers the safety test only. Any repairs to pass are extra, and a service is a separate job. Budgeting a little each year for the MOT plus likely wear items – tyres, pads, bulbs, wipers – is part of the true running cost of a car. If you are still working out those numbers, our breakdown of the real cost of learning to drive is a useful starting point for planning the bigger picture.

Getting road-ready starts before the MOT

The MOT is one of several things that suddenly become your job the day you own a car – alongside tax, insurance and basic upkeep. None of it is complicated once someone shows you, but it lands all at once when you pass, which is exactly why we build these habits in during your course. If you are learning with GetMyPass, our instructors treat you like a driver who will be looking after their own car, not just a candidate ticking off a test.

If you are still on your provisional and weighing up how to learn, our Provisional intensive driving course is built for complete beginners who want to go from a standing start to test-ready efficiently, and our how it works page walks through the whole journey. Once you have passed, a course like Pass Plus builds the extra experience – motorway, night and adverse-weather driving – that also makes you a safer, more switched-on car owner. When you are ready, you can book your course and get started.
