How do I know when my MOT is due?

If you're not sure when your MOT is due, you can check it with our MOT status tool. Or use our app, where you can also check your vehicle tax date and set reminders. 

Always make sure you use a trustworthy mechanic - if you’re not sure where to go, ask friends and family for recommendations.

Driving without a valid MOT is not only illegal, but could invalidate your car insurance


What does an MOT check? 

When you take your car for an MOT, a mechanic will usually check these areas

  • Vehicle identification number (VIN)
  • Registration plate
  • Lights
  • Steering and suspension
  • Wipers and washers
  • Windscreen
  • Horn
  • Seat belts and seats
  • Doors
  • Mirrors
  • Wheels and tyres
  • Brakes
  • Fuel system
  • Exhaust system
  • Vehicle emissions

Often a car fails its MOT test because of a simple fault that's easily solved.

In fact, the most common MOT failures are:

  • Lights and signals
  • Suspension
  • Brakes
  • Tyres
  • Problems affecting view of the road

MOT checklist UK


1. Lights

Check all lights are working correctly. This includes: 

  • Rear lights 
  • Fog lights
  • Brake lights
  • Indicator lights
  • Hazard lights

If you've any bulbs that have blown, check your car’s manual to see if you can replace them yourself.

Check that all warning lights on your dash are working too.


2. Vehicle body and tyres

Take a look at the petrol inlet filler cap. The petrol inlet is where the fuel goes, and the filler cap is what you screw onto it. Look out for any damage to the seal around the cap.

Check if the horn works. It should be loud and clear.

Test the brakes, handbrake and steering wheel. The steering wheel shouldn’t feel loose, and the handbrake shouldn’t pull up too high.

Check all tyres are the correct pressure. Also, check if the tyre tread depth is at least 1.6mm – the legal limit.


3. Windows and mirrors 

Nothing should obstruct your view of the road. Check wiper blades for damage. If they're worn, you can replace them yourself using your vehicle handbook for reference. 

Remove sat nav cradles, stickers and air fresheners if they block your view. 

Mirrors should be secure and intact.


4. Cleaning your car

Registration plates must be readable and in good condition. If you own a personalised number plate, make sure it still meets the DVLA’s requirements.

Make sure the car is presentable, inside and out. If your car is dirty and full of clutter the tester can refuse to carry out the inspection.


5. Documentation

The Vehicle Identification Number (VIN) should match the VIN in your car’s log book. 


6. Fluid levels

Check your screen wash, brake fluid and oil.


What happens after the test?

After the test you'll get a list with everything the mechanic has tested along with the result. The result will either be: 

  • Pass
  • Pass with advisories 
  • Pass with minor faults
  • Fail with major or dangerous faults

What if your car fails its MOT?

If your car comes back with major or dangerous faults, you’ll have to get each issue fixed before you use the car. 

Once fixed you'll need to MOT your car again. This time they’ll only test the faults discovered during the first test.

The MOT test can also identify other, less immediate problems. These will appear as ‘minor faults’ on your certificate. 

Minor faults aren’t yet serious enough to cause your car to fail its MOT. For example, if you have worn tyres, but they're not worn below the legal limit.

After an MOT your pockets might be a little lighter. But it’s a good idea to get the minor faults sorted a month or so after the initial test. 

That way the faults won’t develop and put you in danger. You stand a better chance of passing it the following year too.


What happens when I pass my MOT?

Your garage will give you an MOT test certificate and you’re legal to drive off. Hurrah!

Your test centre will send the results to a central database.

Check-ups and servicing are great for keeping your car healthy, so it's wise to keep them up.  That way you stand a better chance of passing your MOT, and spread out the cost of repairs.
