MOT Checklist: How to Pass Your MOT First Time (2026 Guide)

If your MOT is coming up, the last thing you want is a failure, especially when many issues are quick and easy to fix.

This MOT checklist will help you understand what to check before your test, common reasons for failure, and how to improve your chances of passing first time.

Why Use an MOT Checklist?

Every year, thousands of vehicles fail their MOT due to simple issues that could have been avoided.

Using a checklist before your test can help you:

• Avoid unnecessary repair costs
• Increase your chances of passing first time
• Save time and inconvenience

MOT Checklist: What to Check Before Your Test

Here are the key things you should check before taking your car for an MOT:

1. Lights and Indicators

• Check all headlights (main and dipped beam)
• Ensure brake lights and indicators are working
• Replace any blown bulbs

Faulty lights are one of the most common MOT failures and usually a simple fix to do yourself. 

2. Tyres and Tread Depth

• Minimum legal tread depth is 1.6mm
• Check for uneven wear or damage
• Ensure tyres are correctly inflated

By checking these points before your MOT, you're able to research the best prices for replacing any tyres before your MOT, ensuring you can get the best possible price and save money later. 

3. Brakes

• Listen for squeaking or grinding noises
• Check for reduced braking performance

Brake issues are a common cause for failure. Lean more about brake pad replacement costs and the warning signs to look for. 

4. Windscreen and Wipers

• Check for cracks or chips in the drivers view
• Make sure the wipers clear the screen properly
• Top up windscreen washer fluid

5. Dashboard Warning Lights

• Ensure no warning lights remain on when driving
• Engine management lights can lead to failure

For diesel vehicles, this may indicate DPF problems and repair costs that should be addressed before your test.

6. Number Plates

• Must be clean and fully readable
• Correct any bending or bowing of plates
• Use correct font and spacing

7. Seatbelts

• Ensure all seatbelts fasten correctly and securely
• Ensure no fraying or damage

Common Reasons Cars Fail Their MOT

Even with preparation, some issues are more common than others:

• Worn brake components
• Tyres below legal limit
• Faulty lights
• Suspension problems
• Emissions problems
