MOT - Williams


What is an MOT?

An MOT tests the roadworthiness and safety of your vehicle. If successful, you’ll be issued with an MOT certificate that’s valid for 12 months. If your vehicle fails its MOT, it will need to be retested upon completion of the necessary repairs.

Vehicles aged three years or more must receive an MOT every 12 months.

1. Headlights and indicators

Check that all headlights, taillights and indicators are functioning correctly.

2. Brake lights

While putting your foot on the brake pedal, ask a friend to view the brake lights to see if they’re working properly. Alternatively, carefully position a reflective surface behind your vehicle – this will allow you to press the brakes and check the brake lights at the same time.

3. Number plate

Make sure that both plates are clean and legible, and that the font and character spacing conform to legal requirements.

4. Wheels and tyres

Roughly 60% of failed MOTs are due to defective tyres – so check each wheel for signs of damage and ensure that each tyre has a minimum tread depth of 1.6mm (3mm, ideally).

5. Seat & Seatbelts

The driver’s seat should adjust forwards and backwards and all seatbelts should be in good, working order. Test movement of the seat and inspect the seatbelt’s full length for damage. Tug sharply on all seatbelts to check that they react as they’re supposed to if you have to brake severely.

They save your life in a crash, but only if they work properly – inspect the full length for damage and tug sharply on all the seatbelts to check that they react as they’re supposed if you have to brake severely.

6. Windscreen

From the inside, inspect every part of the windscreen. Any damage that measures 40mm or more will cause an MOT fail. Don’t forget to pay close attention to the area on the driver’s side within the sweep of the wiper – here, the maximum allowable damage size is 10mm.

7. Windscreen​ Wipers

Ensure that both wipers work correctly, and that both rubber blades are free from damage.

8

8. Screenwash

Something as seemingly trivial as an empty screenwash bottle could fail your car’s MOT – make sure it’s topped up!

9. Horn

When you toot the horn, does it work? If not, have it repaired or replaced before your car’s MOT.

10

10. Fuel and engine oil

If applicable, ensure that you have enough fuel and engine oil because the MOT tester will need to run the engine to test exhaust emissions.
