Is your MOT date looming? In the UK, nearly 30% of cars fail their MOT on the first attempt. Most of these failures aren’t caused by major engine failures; they are more often caused by simple, avoidable issues like a blown bulb or empty screenwash.
Failing an MOT is more than just a nuisance; it’s a drain on your wallet and your time. That’s why we’ve put together the Ultimate MOT Prep Checklist. Follow these steps to ensure your car is roadworthy before you head to your local garage.
1. The “Quick 6” Walkaround (Takes 5 Minutes)
Before booking into a garage near you, perform these six checks that account for over half of all MOT failures.
- Lights & Indicators: Turn on every light (headlights, full beams, hazards, and even the rear registration plate light). Ask a friend to stand behind the car while you tap the brakes.
- The Horn: Give it a short, sharp blast. It needs to be loud and clear.
- Number Plates: Ensure they are clean and readable. If the plastic is delaminating or the letters are obscured, it’s an automatic fail.
- Windscreen & Wipers: Check for chips. A chip larger than 10mm in the driver’s line of sight (Zone A) is a fail. Also, ensure your wipers actually clear the water rather than just smearing it.
- Screenwash: Top it up! Testers cannot check your wipers if the reservoir is empty, leading to a “refusal to test” or a failure.
- Dashboard Warning Lights: If your engine management, ABS, or SRS (airbag) lights stay on after you start the engine, your car will fail.
2. The 20p Tyre Test
Tyres are the only contact point between you and the road. The legal minimum tread depth is 1.6mm. * The Test: Take a 20p coin and insert it into the tread grooves. If you can see the outer rim of the coin, your tyres are likely illegal and definitely an MOT fail.
- Check the Walls: Look for bulges, cracks, or “sidewall perishing.”
3. Seats and Safety Belts
Pull every seatbelt in the car to its full length. Look for frays or cuts. Give them a sharp tug to ensure the “inertia reel” locks correctly. Also, make sure the driver’s seat moves forward and backward as it should – if it’s stuck, it’s a failure.
4. Fluids and Emissions
While the tester checks the heavy stuff, you can handle the basics:
- Oil & Coolant: Ensure levels are between the Min and Max markers.
- Fuel: Don’t turn up with the fuel light on. The tester needs to run the engine to check emissions; if they can’t run it, they can’t pass it.
5. Find a Trustworthy Garage Near You
Not all MOT centres are created equal. Using a reputable local garage can save you from being overcharged for minor repairs.
- Check Reviews: Look for garages with great reviews or ask friends or colleagues opinions.
- Compare Prices: MOT prices are capped by the government, but many local garages offer discounts when booked with a service.

Frequently Asked Questions (FAQ)
You can have your MOT carried out up to one month (minus a day) before it expires while keeping your original renewal date. This gives you a “13-month” MOT!
If your current MOT is still valid, you can usually drive it away unless the tester marked a “Dangerous” fault. If it’s “Dangerous,” the car cannot be driven on public roads until fixed.
Statistically, lighting and signalling is the #1 cause of failure (around 25-30%). This is almost always something the owner could have fixed for a few pounds before the test.
The maximum fee a garage can charge for a car MOT is *£54.85 (*£29.65 for a motorocycle MOT), though many independent garages in our directory offer significant discounts.
Final Thought: Don’t Panic Over “Advisories”
If your car passes but has “Advisory” notes, don’t ignore them. These are items that aren’t a fail yet—like thinning brake pads, but will need attention soon. Use our directory to find a specialist who can give you a quote for these minor repairs before they become major bills!
