MOT Fails

Most Common MOT Fails And How To Avoid Them

Every year, countless vehicles head into the test centre for their annual MOT, a requirement for cars over three years old in the UK. Yet, a substantial number of these vehicles fail their MOT test, resulting in added costs, stress, and even potential dangers on the road. The RAC Drive statistics suggest that many of these MOT failures could have been easily prevented with some proactive checks and maintenance. In this article, we will delve deep into the common MOT fails and guide how to steer clear of them.

Understanding the common reasons for MOT failures can not only save you money but also ensure that your vehicle is safe to drive. The Driver and Vehicle Standards Agency (DVSA) outlines specific criteria that vehicles must meet to receive an MOT certificate. If your vehicle fails its MOT test, you’re legally obliged to get the issues fixed before you can drive your vehicle again, unless your current MOT certificate is still valid. Let’s look at the areas where most vehicles trip up and how you can avoid being a part of those statistics.

MOT Fail List

Here are the top MOT failure categories:

  1. Lamps, reflectors and electrical equipment
  2. Suspension
  3. Brake lights
  4. Brakes
  5. Tyre condition
  6. Driver’s view of the road
  7. Headlamps
  8. Registration plate
  9. Indicators

1. Lamps, Reflectors, and Electrical Equipment

One of the top reasons vehicles fail the MOT test is due to problems with lamps, reflectors, and other electrical equipment. Whether it’s a simple bulb that’s burnt out or a malfunctioning indicator, these issues can lead to an MOT failure.

How to Avoid: Regularly check all your lights – including brake lights, indicators, and headlights. Replace any burnt-out bulbs and ensure all electrical connections are clean and tight. It’s a simple step in your MOT checklist but can save you from an unexpected failed MOT.

2. Suspension

Suspension issues, especially in older cars, can be a primary cause of an MOT failure. Worn-out shock absorbers or damaged springs can affect the vehicle’s handling and safety.

How to Avoid: Be attentive to any changes in your vehicle’s handling. If you notice excessive bouncing, a tilt to one side, or hear clunking noises, it might be time to check the suspension. Regular checks and addressing issues immediately can prevent this MOT from failing.

3. Brake Lights

Brake lights play a critical role in signalling to other drivers when you’re slowing down or stopping. A malfunctioning brake light is not only an MOT fail but also a safety hazard.

How to Avoid: Periodically, with the help of a friend or using a reflective surface, check if all your brake lights are functioning properly. Replace any non-working bulbs and ensure there’s no electrical issue causing the malfunction.

4. Brakes

Faulty brakes are a major safety concern and a common reason for vehicles to fail their MOT. From worn-out brake pads to issues with brake fluid, there are several potential pitfalls here.

How to Avoid: Listen for any unusual sounds when braking, and feel for any changes in brake performance. Getting an annual full car service can help identify and rectify brake issues before they cause your vehicle to fail the MOT.

5. Tyre Condition and Tread Depth

Poor tyre conditions can lead to MOT fails. Balding tyres, cuts, or bulges can be dangerous on the road, affecting grip and vehicle stability.

How to Avoid: Regularly inspect your tyres for any visible damage and use a tread depth gauge to ensure they’re above the legal limit of 1.6mm. Keeping your tyres at the right pressure can also prolong their lifespan.

6. Driver’s View of the Road

Windscreen issues, such as large chips or cracks that block the driver’s view of the road, can result in an MOT fail. Even issues with wiper blades can cause your vehicle to fail the test.

How to Avoid: Ensure your windscreen is free of large cracks and chips. Replace worn-out wiper blades, and regularly top up with a good quality screen wash.

7. Headlamps

Like other lights on your vehicle, malfunctioning headlamps can cause an MOT to fail.

How to Avoid: Regularly check the functionality and alignment of your headlamps. Replace bulbs as needed and consider professional help if alignment issues persist.

8. Registration Plate

Registration Plate

A dirty, damaged, or incorrectly spaced number plate can lead to your vehicle failing its MOT test.

How to Avoid: Keep your number plate clean and ensure it meets the DVSA standards for font, size, and spacing. Replace damaged plates before your MOT is due.

9. Indicators

Indicators signal your intentions on the road, and faulty ones can lead to an MOT failure.

How to Avoid: As with all other lights on your vehicle, routinely check and replace faulty bulbs or address any electrical issues causing malfunctions. While the annual MOT might seem daunting, a proactive approach towards vehicle maintenance can significantly reduce the risk of an MOT failure. With many vehicles failing due to easily preventable issues, making regular checks and addressing problems promptly can save both time and money. Before your next MOT due date, be sure to go through an MOT checklist, ensuring each point is addressed, leading to a higher likelihood of your vehicle passing its MOT with flying colours. Remember, it’s not just about securing that MOT certificate; it’s about ensuring your vehicle is safe on the road for you and others.
