What Does the UK MOT Test Check For? | Rooster
Jan 21, 2025

The MOT (Ministry of Transport) test is a mandatory annual inspection in the UK to ensure that vehicles meet road safety and environmental standards. If you own a vehicle that is more than three years old, an MOT test is essential to confirm its roadworthiness. But what does the UK MOT test check for? Let’s dive into the key aspects covered in this inspection.

1. Lighting and Signalling Equipment

The MOT test thoroughly examines all lighting and signalling systems. This includes headlights, indicators, brake lights, and fog lights. They must all function correctly, be securely fitted, and emit the appropriate light colour. Faulty or broken lights are one of the most common reasons for MOT failures.

2. Steering and Suspension

The steering and suspension systems are critical for maintaining vehicle control and stability. During an MOT, these components are inspected for excessive wear, corrosion, or damage. A steering wheel that doesn’t respond properly or suspension issues, such as worn shock absorbers, can result in a failed test.

3. Brakes

Braking performance is a vital part of road safety. The MOT test checks the condition and efficiency of the braking system, including brake pads, discs, and callipers. This test also involves measuring braking force on a rolling road to ensure even braking across all wheels.

4. Tyres and Wheels

Your vehicle’s tyres and wheels are inspected for tread depth, damage, and general condition. Tyres must have a minimum tread depth of 1.6mm across the central three-quarters of the tyre, and there should be no significant cuts or bulges.

5. Exhaust and Emissions

To comply with environmental regulations, the MOT test includes an emissions check. The test assesses the level of pollutants emitted by the vehicle’s exhaust system. Any excessive smoke or leaks in the exhaust system can lead to a failure.

6. Body, Structure, and General Condition

The overall structure of the vehicle is inspected for corrosion, damage, or any defects that could compromise safety. Doors, mirrors, and fuel tank caps must be securely attached and in good condition. Any sharp edges on the bodywork that could harm pedestrians will also result in a failed MOT.

7. Seat Belts and Seats

Seat belts are vital safety features, and the MOT test ensures they are in good working order. They must be securely attached, free from damage, and capable of restraining passengers effectively. The test also checks that seats are securely fixed.

8. Windscreen, Wipers, and Washers

A clear view of the road is essential, so the MOT test examines the windscreen for cracks or chips, particularly in the driver’s line of sight. Wipers and washers must be functional and able to clear the windscreen effectively.

9. Horn

The horn must work properly to warn other road users of potential hazards. It should emit a sound that is loud enough to be heard by other drivers and pedestrians.

10. Vehicle Identification Number (VIN)

Every vehicle must display a clear and legible VIN. This unique number is checked during the MOT to ensure it matches the vehicle’s records.

Why Regular MOT Checks Are Crucial

Regular MOT tests are not just a legal requirement but a vital step in ensuring your vehicle is safe for you, your passengers, and other road users. Additionally, they help reduce harmful emissions, contributing to a cleaner environment.
