The annual MOT test is a legal requirement for vehicles over three years old in the UK, ensuring that they meet minimum safety and environmental standards. However, many cars fail their MOT on preventable issues. In this guide, we’ll explore the top four reasons why cars commonly fail their MOT and how you can avoid these pitfalls.
1. Faulty or Damaged Lights
One of the most common reasons for MOT failures is faulty or damaged lights. Whether it's a blown headlamp bulb, a broken brake light, or misaligned headlights, lighting issues are easy to spot and relatively simple to fix.
How to Avoid It:
-
Regularly check all lights, including indicators, brake lights, and fog lights.
-
Replace any blown bulbs promptly.
-
Ensure headlights are properly aligned.
2. Worn Tyres
Tyres are another frequent culprit for MOT failures. Worn-out tread, damage, or incorrect pressure can all result in an automatic fail.
How to Avoid It:
-
Check tyre tread depth regularly (it must be at least 1.6mm across the central three-quarters of the tyre).
-
Inspect tyres for cuts, bulges, or visible damage.
-
Ensure tyre pressure meets the manufacturer’s specifications.
3. Brake Issues
Faulty brakes are a significant safety concern and one of the leading reasons for MOT failures. This includes worn brake pads, damaged discs, or brake fluid leaks.
How to Avoid It:
-
Listen for unusual noises when braking.
-
Have your brakes checked regularly by a professional.
-
Replace worn brake pads and discs when needed.
4. Visibility Problems
Visibility issues, such as cracked windscreen glass, worn wiper blades, or insufficient screen wash, can result in an MOT fail.
How to Avoid It:
-
Repair or replace any chips or cracks in the windscreen.
-
Ensure wiper blades are in good condition.
-
Top up screen wash regularly.
Preparing for Your MOT
Preventing an MOT failure often comes down to regular maintenance and pre-test checks. Here are some quick tips:
-
Book a pre-MOT inspection with a trusted mechanic.
-
Fix minor issues before the test.
-
Keep up with your car’s servicing schedule.
Final Thoughts
