What Is Checked During an MOT Test?

An MOT test is a detailed inspection that ensures your vehicle meets UK safety and environmental standards. Testers scrutinise a wide range of components to confirm the vehicle remains roadworthy and compliant with legal requirements.

1. Brakes: Both foot brake and parking brake performance are checked, along with pads, discs, and hydraulic components. Uneven braking or worn parts can trigger an immediate fail.

2. Lights: Headlights, indicators, brake lights, fog lights, and reversing lights must all work correctly and be properly aligned.

3. Tyres: Tyres must have at least 1.6mm tread depth, the correct load rating, and no damage such as cuts or bulges.

4. Suspension: Shock absorbers, springs, and other suspension components are examined for leaks, corrosion, or wear that could affect handling.

5. Emissions: Vehicles must meet the emissions limits for their age and fuel type. Excessive smoke or a malfunctioning catalytic converter can cause a fail.

6. Exhaust System: Testers look for leaks, secure mounting, and correct noise levels to ensure the exhaust is functioning efficiently.

7. Windscreen and Wipers: Chips or cracks that obstruct the driver's view lead to a fail, as do wipers that cannot clear the screen effectively.

8. Steering: Steering racks, power assistance, and the general responsiveness of the wheel are assessed for excessive play or leaks.

9. Vehicle Structure: The chassis and body are inspected for corrosion, damage, or repairs that might reduce crash safety.
