Understanding the MOT Test
The MOT test checks a range of vehicle components to make sure they’re roadworthy. These include:
- Lighting and signaling
- Brakes and tyres
- Suspension and steering
- Windscreen, mirrors, and wipers
- Emissions and exhaust systems
- Seatbelts and body condition
The Driver and Vehicle Standards Agency (DVSA) outlines all parts inspected during an MOT on its official website. Many failures stem from issues that could be fixed with simple maintenance.
Common MOT Failures and How to Avoid MOT Failure With These Expert Tips
1. Lighting and Signaling Issues
Lights account for nearly a quarter of all MOT failures. It’s often just a blown bulb or a dirty lens.
Avoidance Tips:
- Walk around your car weekly to check all lights, including indicators, brake lights, fog lights, and number plate illumination.
- Replace blown bulbs immediately. They cost as little as £5–£10.
- Clean all light covers to ensure maximum visibility.
2. Tyre Problems
Tyres must have a tread depth of at least 1.6mm and be free from cuts, bulges, or severe wear.
Avoidance Tips:
- Use the “20p test” to check tread depth.
- Visually inspect tyres for damage or uneven wear.
- Inflate tyres to the manufacturer’s recommended pressure.
Expert Insight:
John Miller, a DVSA-certified mechanic, notes: “Many failures come from bald tyres or mixed tread depths. A quick £60 replacement tyre can prevent a £400 repair and retest combo.”
3. Brake Issues
Brakes account for about 16% of MOT failures. Faded pads, warped discs, or low brake fluid can all lead to a fail.
Avoidance Tips:
- If you hear squealing or grinding, have your brakes checked immediately.
- Keep an eye on the brake fluid level.
- Check for vibrations or pulling when braking.
Cost Estimates:
- Brake pad replacement: £80–£120
- Discs and pads: £200–£300
4. Suspension Problems
Worn or damaged suspension can affect handling, ride comfort, and safety. This category makes up 19% of failures.
Avoidance Tips:
- Listen for clunking noises when going over bumps.
- Look for fluid leaks near shock absorbers.
- Do the “bounce test” – press down on each corner of the car; it should rebound once and settle.
5. Driver Visibility
Anything that restricts the driver’s view, such as windscreen damage, faulty wipers, or items hanging from the rear-view mirror, can cause an MOT fail.
Avoidance Tips:
- Replace worn wiper blades annually.
- Clear the windscreen and mirrors before every journey.
- Repair windscreen chips early—many insurers cover this for free.
