Introduction
The annual MOT test can feel like a hassle, but it’s essential for keeping your vehicle safe and roadworthy. Whether you’re a seasoned driver or booking your first MOT in Sudbury, knowing what inspectors look for can save you time, money, and stress.
At Approved Engines, a leading MOT Test Centre in Suffolk, we’ve put together this complete MOT checklist to help you pass your test for the first time — and avoid those common pitfalls.
What Is Checked During an MOT?
The MOT test checks key areas of your vehicle to ensure it meets UK road safety and environmental standards. These include:
- Lights & Signals
- Tyres & Wheels
- Brakes
- Windscreen & Wipers
- Mirrors
- Seatbelts
- Suspension & Steering
- Exhaust & Emissions
- Registration Plates
- Horn & Warning Systems
Now let’s look at what you can check yourself before your appointment.
Pre-MOT Checklist: 12 Things to Check
1. Lights & Indicators
- Check all exterior lights — headlights, brake lights, indicators, and number plate lights.
- Replace any bulbs that aren’t working.
2. Tyres
- Tread depth must be at least 1.6mm across the central ¾ of the tyre.
- Look for cracks, bulges, or uneven wear.
- Ensure tyre pressures are correct.
3. Brakes
- Your car should stop smoothly and in a straight line.
- Listen for squealing or grinding sounds — these may indicate worn brake pads.
4. Windscreen & Wipers
- Make sure your windscreen is free from cracks or chips in the driver’s view.
- Wipers should clear water effectively — replace if smeary or worn.
5. Screen Wash
- Top up your washer fluid — yes, this small thing can cause an MOT failure!
6. Mirrors
- All mirrors must be securely attached and provide clear visibility.
- Clean them before your MOT.
7. Horn
- Give it a toot — it should sound loud and clear.
8. Seatbelts
- Check all seatbelts for frays, cuts, or stiffness.
- Tug them sharply — they should lock immediately.
9. Steering & Suspension
- If the steering feels loose or you hear clunks when turning, get it checked before your test.
10. Number Plates
- Must be clean, clearly visible, and securely attached.
- The font and spacing must meet legal requirements.
11. Exhaust
- Excessive smoke or unusual noise may signal a problem.
- Look underneath for any signs of leaks or rust.
12. Dashboard Warning Lights
- Any illuminated warning lights (engine, ABS, airbag, etc.) could lead to a fail.
When Should You Book Your MOT?
You can book your MOT up to 1 month (minus a day) before it’s due and keep the same renewal date for next year. This gives you a buffer to make any repairs if needed — without losing your renewal window.
