The annual MOT (Ministry of Transport) test is a legal requirement for vehicles over three years old in the UK. It ensures your car meets the minimum safety and environmental standards set by the government. Failing an MOT can be inconvenient and costly, but with the right preparation, you can increase your chances of passing on the first attempt. This guide will walk you through a complete checklist to help you get your car ready for its MOT test.
Check your lights
Faulty lights are one of the most common reasons for MOT failures. To avoid this:
- Check that all external lights, including headlights, indicators, brake lights, fog lights and number plate lights are working.
- Replace any blown bulbs and ensure they are the correct brightness and alignment.
- Clean any dirty or foggy light covers to improve visibility.
Test your brakes
Brakes are critical for vehicle safety and are thoroughly checked during an MOT test.
- Listen for any unusual noises when braking, such as grinding or squeaking.
- Ensure the brake pedal doesn’t feel too soft or spongy.
- Check your handbrake to ensure it holds the car securely on an incline.
If you notice any issues, get your brakes checked by a professional before the test.
Inspect your tyres
Your tyres must meet legal requirements to pass the MOT test.
- Ensure your tyres have a minimum tread depth of 1.6mm across the central three-quarters of the tyre.
- Check for any visible damage, such as cuts, bulges, or punctures.
Ensure the tyres are properly inflated according to the manufacturer’s recommended pressure.
Ensure your windscreen and wipers are in good condition
Your windscreen should be clear of obstructions and damage.
- Look for any cracks or chips larger than 10mm in the driver’s line of sight or 40mm elsewhere.
- Check that your wipers are working effectively and that the blades are not torn, damaged, or leave smears across the glass.
- Top up the windscreen washer fluid to ensure clear visibility.
Test your horn
Your horn should be loud and clear. Press the horn and listen for a strong, continuous sound. If it’s weak or silent, it may need replacing before the MOT.
Examine your exhaust system
Your car’s exhaust system is tested for emissions and leaks.
- Start the engine and listen for any unusual noises, such as excessive rattling or loud exhaust sounds.
- Look for visible smoke, which could indicate an emissions problem.
If your exhaust has excessive rust or damage, consider getting it checked before your MOT.
Check your mirrors and number plates
Ensure all mirrors are securely attached and not cracked and clean your number plates and make sure they are clearly visible, properly fixed and match legal font and spacing regulations.
Top Up Fluids
Ensure that all essential fluids are at appropriate levels before your MOT test:
- Engine oil: use the dipstick to check levels and top up if necessary.
- Coolant: ensure your coolant level is between the minimum and maximum marks.
- Brake fluid: low levels can indicate a leak and may result in a failed MOT.
- Windscreen washer fluid: refill as needed to maintain clear visibility.
Check your suspension
Your suspension system is checked for excessive wear or damage.
- Push down on each corner of your car and see if it bounces excessively.
- Listen for any knocking or creaking noises when driving over bumps.
- If you experience a rough or bumpy ride, get your suspension checked before your MOT.
Ensure your fuel cap is secure
Check that your fuel cap is securely fitted and does not leak. If your fuel cap is missing or faulty, replace it before the test.
Keep your car clean and presentable
A dirty car inside and out may not fail an MOT, but an excessively cluttered or messy interior could cause issues, especially if it obstructs essential components like the handbrake or pedals. Ensure:
- The interior is tidy, with nothing blocking footwells or mirrors.
- The exterior is clean enough to allow easy inspection of lights and number plates.
What happens if your car fails the MOT?
If your vehicle fails the MOT test, you will receive a VT30 Refusal of an MOT Certificate explaining the reasons for failure. You can:
- Get repairs done immediately and have a free retest if completed at the same test centre within 10 working days.
- Take your car to another garage for repairs and then rebook the MOT test.
- You can drive the car only if your previous MOT is still valid and the car is not deemed dangerous.
Final tips to pass your MOT first time
- Book your MOT early: don’t wait until the last minute; schedule it in advance to allow time for repairs if needed.
- Do a pre-MOT check: running through this checklist a few weeks before your test can help you spot issues early.
- Use a reputable garage: a trusted garage can give honest feedback and guidance on any necessary repairs.
- Consider an MOT and service package: many garages offer combined deals to help keep your car in the best condition.
