The Top Most Common MOT Fails and How to Avoid Them
Aug 10, 2023

When it comes to ensuring your vehicle's roadworthiness and safety, the MOT (Ministry of Transport) test is a crucial aspect. Each year, countless vehicles fail their MOT for various reasons, often leading to costly repairs and inconvenience for the owners. So let's explore the most common MOT fails and how to avoid them, ensuring your vehicle likelihood at sailing through the MOT test with flying colours.


Faulty Lights and Signalling

One of the primary reasons vehicles fail their MOT is due to faulty lights and signalling systems. Before taking your car for the MOT test, take the time to inspect all exterior lights, including headlights, taillights, brake lights, indicators, and fog lights. Replace any blown bulbs and ensure they are correctly aligned to avoid any unnecessary failures.

Worn Out Tyres

Tyres are another common reason for MOT failures. Check your tyre tread depth and ensure it meets the legal requirement of at least 1.6mm across the central three-quarters of the tyre. You can use the 20p hack for this, see here! Additionally, check for any visible damage or bulges on the sidewalls. Regularly maintaining and rotating your tyres can also prolong their lifespan and prevent uneven wear.

Windscreen and Wipers

A chipped or cracked windscreen in the driver's line of vision can lead to MOT failure. Inspect your windscreen for any damage and have it repaired promptly. Additionally, check your wipers for wear and tear, ensuring they effectively clear the windscreen during rain. Replacing windscreen wipers is one of the lowest car maintenance costs, so be sure to replace when necessary.

Brake System Issues

The braking system is a critical safety component in any vehicle. To avoid MOT failure, regularly check your brake pads, discs, and brake fluid levels. Squealing or grinding noises while braking are warning signs of worn-out brake pads. Address any brake-related issues promptly to ensure your vehicle is roadworthy.

Suspension Problems

Faulty suspension systems can lead to MOT failure and compromise the handling and stability of your vehicle. Regularly inspect your car's suspension for leaks, worn-out components, and damaged shock absorbers. If you notice excessive bouncing or uneven tire wear, it's time to have your suspension checked and repaired.

Exhaust Emissions

Exhaust emissions are thoroughly tested during the MOT, and high emissions can result in failure. Regularly service your vehicle and ensure the engine is in optimal condition to minimise emissions. If your car emits visible smoke, it may indicate a more severe problem that needs immediate attention.

Seatbelts and Seats

Non-functional seatbelts or damaged seat anchors can lead to immediate MOT failure. Test all seatbelts to ensure they retract and latch correctly. Also, check for any tears or fraying. Inspect the seats for stability and ensure they are securely bolted in place.

Keeping your vehicle in excellent condition is essential not only for passing the MOT but also for your safety and that of others on the road. Regular maintenance and proactive inspections can go a long way in preventing common MOT fails. Address any issues promptly and enlist the help of a professional mechanic if needed. By following these tips and staying on top of your vehicle maintenance, you'll increase the chances of your vehicle passing the MOT test with ease. This will provide you with peace of mind and ensure your road safety. Thanks for reading The Top Most Common MOT Fails and How to Avoid Them!
