So you’re a UK driver, and you’ve heard of the MOT test – that annual vehicle inspection designed to keep cars safe and roadworthy. But what exactly is the MOT, and why is passing it so important?
The MOT (Ministry of Transport) test is a legal requirement for most vehicles over three years old. It checks key safety and environmental standards to ensure your car is fit for UK roads. Understanding the top MOT fails in the UK can help you avoid the stress of a failed test.
At ABSMOTS, Nottingham’s trusted MOT test and vehicle service provider, we want to help you stay road-ready. In this post, we’ll break down the most common MOT failures in the UK, why they happen, and how to pass your MOT test in Nottingham with confidence.
Why Do So Many Cars Fail Their MOTs?
Every year, thousands of vehicles fail their MOTs. According to the Driver and Vehicle Standards Agency (DVSA), around 30% of cars fail on the first attempt. But why is that figure so high?
Several reasons:
- Lack of regular maintenance: Many drivers don’t do routine checks, and worn-out parts go unnoticed.
- Age of vehicle: Older cars develop issues like worn brakes or suspension problems.
- Unawareness of MOT requirements: Some drivers don’t know what the test covers or how to prepare.
- Neglect of minor faults: Small issues like faulty bulbs or tyre tread depth can fail if ignored.
Knowing these reasons helps you take proactive steps to keep your car in top shape and avoid unexpected MOT test failures.
Top MOT Fails in the UK (With Stats)
Let’s get into the most common reasons vehicles fail their MOTs, based on recent UK statistics:
1. Lights and Signalling (Around 20% of fails)
Faulty headlights, brake lights, indicators or number plate lights are the biggest MOT fail. Even one blown bulb can fail you, as proper lighting is crucial for safety.
2. Tyres and Wheels (Approximately 15%)
Tyres with less than 1.6mm tread depth, damage or incorrect pressure often fail. Worn or damaged tyres compromise grip and braking performance.
3. Brakes (About 10%)
Brake issues like worn pads, discs or uneven braking force are serious safety concerns. The MOT test checks braking efficiency and condition.
4. Suspension (Around 8%)
Worn suspension parts cause poor handling and tyre wear. MOT testers look for leaks, damage and excessive play.
5. Exhaust and Emissions (7%)
Vehicles producing excessive smoke or failing emissions limits will fail. Exhaust leaks or damaged parts will also fail.
6. Windscreen and Wipers (6%)
Cracks, chips or poor wiper performance affecting visibility will fail.
7. Seatbelts and Seats (5%)
Damaged or missing seatbelts and loose seats are safety hazards.
How to Avoid These Common MOT Fails
You’ll pass your MOT if you maintain your vehicle. Here’s how:
- Check all lights weekly: Replace any blown bulbs.
- Check tyres monthly: Tread depth and damage, and pressure.
- Listen for brake noises: Squealing or grinding means it’s time for a checkup.
- Watch for suspension issues: Any unusual noises or poor handling.
- Keep your exhaust in good nick: Address any leaks or strange noises.
- Keep your windscreen and wipers clean: Replace worn wiper blades and repair chips.
- Ensure seatbelts work: Check for fraying or damage.
Regular servicing and small repairs will save you from costly MOT failures.
DIY Pre-MOT Checklist
Before you book your MOT, use this quick checklist to spot common problems:
- All lights (headlights, indicators, brake lights, number plate lights) are working
- Tyres have at least 1.6mm tread depth and no visible damage
- Brakes feel firm and responsive; no unusual noises
- Suspension shows no leaks or excessive movement
- Windscreen is free from large chips or cracks
- Wipers clear the windscreen
- Seatbelts fasten and release correctly
- The exhaust system is intact with no leaks or excessive noise
- Horn works
- Mirrors are secure and undamaged
If you find any issues, it’s best to get them sorted before your MOT.
Should You Fix Small Issues Before the MOT Test?
Yes. Some small faults might seem minor, but they can fail your MOT. Fixing a blown bulb or low tyre pressure is usually cheap and quick. Waiting until the test day to sort issues can result in failure, wasted time, and extra repair costs.
