The Essential Pre-MOT Checklist You Can Do Yourself at Home
Every vehicle on UK roads older than three years must pass an annual MOT (Ministry of Transport) test to ensure it meets crucial road safety and environmental standards. But here’s a little secret: many common MOT failures can be avoided by performing a simple pre-MOT check yourself at home. That’s right, no need to summon a mechanic in a superhero cape just yet. A bit of DIY attention before your MOT appointment could save you from costly repairs, retests, and that sinking feeling of “Oh no, not again!”
In this handy guide, we’ll walk through the essential pre-MOT checklist you can do yourself at home. No special skills required—just some curiosity, a few basic tools, and maybe a willing family member to help check those tricky lights!
Why Do a Pre-MOT Check?
The MOT test covers everything from brakes to lights, tyres to exhaust, and steering to emissions. If even one aspect doesn’t quite meet the required standards, your car won’t pass. That means more time and money spent fixing problems and scheduling retests.
By performing a pre-MOT inspection yourself, you can:
- Spot minor faults early and fix them before the MOT
- Avoid unexpected failures and costly retests
- Boost your chances of passing first time
- Keep your vehicle safer for you and other road users
The Essential Pre-MOT Checklist You Can Do At Home
1. Lights
Lights can be sneakily responsible for many MOT fails. Make sure you check every exterior light, including:
- Headlights (both main beam and dipped beam)
- Side and rear lights
- Brake lights
- Indicators and hazard lights
- Number plate lights
- Fog lights (front and rear)
Pro tip: perform this check in a dark garage or evening dusk and use a reflective surface or a helpful buddy to confirm your lights are working and flashing correctly. Also, don’t ignore cracked or foggy light covers—they’re not just ugly, they reduce effectiveness and can cause a fail.
2. Tyres
Your tyres are literally the only bit of your car touching the road, so make sure they’re up to scratch! Check the tread depth with a tread gauge or a trusty 20p coin—the legal limit is 1.6mm across the central three-quarters and entire circumference.
Also, look out for:
- Uneven wear patterns
- Bulges, cracks, or sidewall damage
- Tyre pressures—use a gauge and inflate to recommended levels found in your vehicle manual or door sticker
Worn or badly inflated tyres aren’t just an MOT fail—they’re a safety hazard. So keep those wheels happy!
3. Windscreen and Wipers
Glance over your windscreen for any chips or cracks. Keep in mind, damage bigger than 10mm in the driver’s direct view or over 40mm elsewhere will likely cause a fail.
Next, test your wipers:
- Do they clear water effectively without streaks?
- If blades are worn or split, they need replacing.
- Check the windscreen washer fluid – top up and test its spray.
Clear visibility is a no-brainer for safety and an MOT must-pass criteria.
4. Mirrors
Ensure all mirrors are present, undamaged, and securely attached:
- Look for cracks or chips on the glass
- Check the mirrors adjust and hold position properly
- Inspect the mounting brackets for stability
A missing or wobbly mirror isn’t just annoying—it’s an MOT fail waiting to happen.
5. Brakes
While you can’t do a full brake test without specialist gear, some quick home checks include:
- Press the brake pedal to feel if it’s firm and doesn’t sink dramatically
- Test the handbrake on a gentle slope to ensure it holds firmly
- Listen for any strange noises while driving when applying brakes
- Check brake fluid under the bonnet and top up if low
Good brakes are the superstar of any MOT pass and your ticket to safe driving.
6. Exhaust System
Inspect your exhaust pipe for signs of trouble:
- Excessive noise (hello, leaks!)
- Rust or holes around joints and hangers
- Unusual fumes or smells
A dodgy exhaust might sound like a fun new feature, but it risks an MOT fail and pollution penalties.
7. Fluid Levels
Keep an eye on all essential fluids:
- Engine oil – check with the dipstick
- Coolant – inspect reservoir markings
- Brake fluid
- Power steering fluid (if applicable)
Make sure to top them up as needed. An engine running low on oil or coolant isn’t just at risk of failing—it’s crying out for mercy.
8. Seat Belts
Seat belts are your best friends on the road, so check that:
- All belts are present and securely attached
- Pull each belt sharply to ensure the lock engages
- Look for damage like frays or cuts
Faulty seat belts? Not on this MOT watch!
9. Horn
Give your horn a quick toot—make sure it’s loud and clear. It might not win you any awards, but a faulty horn is a red flag at MOT time.
10. Number Plates
Check your number plates so they:
- Are clean, visible, and properly lit at night
- Have no cracks, fading, or loose fittings
- Follow the correct font and size regulations
Blurry or missing plates won’t speed you through the MOT lanes.
11. Suspension and Steering
Try the simple bounce test: press down firmly on each corner of the car. It should rebound and settle quickly. If it keeps bouncing, your suspension might be on a break.
Also, while driving, listen for knocking noises or check for uneven steering—both warning signs before you head to your MOT.
12. Interior Checks
Turn the ignition on and look for any warning lights that hang around longer than a caffeinated driver—those could hint at underlying problems.
Test dashboard controls such as demisters, fans, heaters, and seat adjusters. A comprehensive check helps keep your MOT stress-free.
Final Tips for a Successful Pre-MOT
- Perform checks during daylight and on level ground for accuracy
- Gather basic tools like a tyre pressure gauge, a 20p coin, and some cleaning supplies for a thorough inspection
- If you spot bigger problems, don’t hesitate to book a service with a trusted mechanic well before your MOT date
Conclusion
Doing the essential pre-MOT checklist you can do yourself at home is easier than you think and can save you time, money, and a good dose of stress. Catching and fixing minor issues early means you can cruise through the MOT first time and drive with confidence.
Give your car a bit of TLC before the big day—your vehicle (and your wallet) will thank you. Now go on, get checking, and happy motoring!
Drive safely!
