An MOT test is an essential requirement for vehicles over three years old in the UK. It ensures that your car adheres to road safety and environmental standards as mandated by law. The test comprises a series of checks to guarantee that your vehicle is safe to drive and causes minimal harm to the environment.
MOT tests are performed yearly to maintain the highest levels of safety on UK roads. This mandatory procedure not only promotes a better driving experience for everyone but also safeguards the well-being of the environment. By understanding the components of an MOT test, you can ensure your vehicle remains roadworthy and compliant with the law.
What Checks Are Included in an MOT Test?
Axles, Wheels, Tyres, and Suspension
Your vehicle's axles, wheels, tyres, and suspension system will be inspected for any signs of damage or wear. Tyre condition, including tread depth, is crucial to ensure safety on the road, while the suspension system should perform effectively for a comfortable ride.
Body, Structure, and Attachments
During the MOT test, the overall structure of your vehicle will be assessed for any significant corrosion or damage. This includes the bodywork, doors, seats, exhaust system, and any other attachments.
Steering
The steering system, including the steering wheel and power steering components, will be checked for proper functioning and any signs of excessive wear or play. It's important that your steering accurately responds to your input.
Brakes
Your brakes will be thoroughly assessed, including the brake servo unit, master cylinder, pipes, and pedals. This check will look for issues such as excessive movement, wear, or leakage. Your vehicle will also undergo a brake efficiency test.
Brake Fluid Contamination
The brake fluid will be inspected for contamination, which may negatively affect the performance of your brakes and compromise your vehicle's safety.
Brake Pads Warning Light
The brake pads warning light on your dashboard will be checked to ensure it's working properly and giving accurate information to prevent brake-related accidents.
Fuel System
Your vehicle's fuel system will be examined to ensure proper function and compliance with environmental standards, including connections and components. Any leaks or issues will need to be addressed before your vehicle can pass the MOT test.
Exhaust Emissions
The exhaust emissions will be tested to confirm your vehicle meets the required environmental standards. Excessive emissions may indicate issues with engine performance or faults within the exhaust system.

Diesel Particulate Filter (DPF) for Tampering
If your vehicle has a Diesel Particulate Filter (DPF), it will be checked for any signs of tampering or removal. Alteration or removal of the DPF is prohibited and can lead to MOT test failure.
Fluid Leaks Other than Coolant and Adblue
Inspectors will check for other fluid leaks, such as engine oil and transmission fluid, as they can pose a risk to the environment and affect your vehicle's performance.
Lights, Battery, and Electrical Wiring
All vehicle lights - including headlights, indicators, and tail lights - will be assessed for proper functionality. The battery and electrical wiring will also be inspected for any issues or deterioration.
Daytime Running Lights
MOT testers will check your vehicle's daytime running lights to make sure they're functioning correctly. They help improve visibility, so it's essential they work effectively.
Reversing Lights
Reversing lights will be checked for proper operation as they play a vital role in visibility and safety when reversing your vehicle.
Horn
The horn will be tested for functionality and appropriate volume to ensure it can alert other road users effectively.
Number Plates
Your vehicle's number plates will be inspected for correct font, spacing, and display. It's important that they're clearly visible and follow legal requirements.
Seatbelts
All seatbelts will be tested for proper function, security, and wear. It's crucial that they can effectively restrain you and your passengers in the event of an accident.
Speedometer
The speedometer will be checked to ensure it's accurately displaying your vehicle's speed, helping you stay within the legal speed limits.
Visibility (Wipers, Windscreen, Mirrors)
Finally, inspectors will check your wipers, windscreen, and mirrors for any damage or obstructions that might impair your visibility when driving. A clear view of the road is crucial for safe driving.
Wrapping Up
During an MOT test, various components of your vehicle are checked to ensure they meet the legal road safety and environmental standards. Some of the critical parts examined include:
- Lamps and signals: This includes the functionality and alignment of headlights, tail lights, indicators, and hazard lights.
- Braking systems: The efficiency, condition, and operation of the brake system components are assessed.
- Tyres and wheels: Tyre condition, size, pressure, and wheel alignment are checked for compliance with the law.
- Suspension and steering systems: The functionality and safety of shock absorbers, springs, joints, and bearings are scrutinised.
- Seatbelts and seats: The function, security, and condition of these components are verified.
- Exhaust system and emissions: The condition of the exhaust system and your vehicle's emissions are checked to match the environmental standards.
- Body and chassis: A visual inspection of the vehicle's structure ensures it is free from damage or corrosion that could affect safety.
- Vision devices: Safety elements such as mirrors, wipers, and windscreen are examined to ensure clear visibility.
Remember to maintain your vehicle consistently and adhere to its service schedule to improve the chances of passing the MOT test. Regular maintenance not only aids in keeping your vehicle in a safe and roadworthy condition, but may also reduce the overall cost of vehicle upkeep in the long run.
