How to Prepare Your Car for an MOT in Petersfield

22/09/2026 · 5 min read

An MOT test can feel like a stressful annual hurdle, but almost half of all MOT failures are caused by minor issues you can easily check and fix yourself before handing over your keys.

Whether you commute daily along the A3 or drive the rural lanes between Petersfield, Midhurst, and Chichester, a little preparation goes a long way towards securing a pass. Here is our practical guide to getting your car ready for its MOT.

### 5 Quick Pre-MOT Checks You Can Do at Home

**1. Lights and Indicators** Walk around your vehicle and check every single light: headlights (main and dipped), brake lights, indicators, hazard lights, reverse lights, and registration plate lights. Ask a friend or neighbour to stand behind the car while you press the brake pedal, or park near a reflective window. Faulty bulbs are one of the most common—and easily preventable—reasons for an MOT failure.

**2. Windscreen and Wipers** Check your windscreen for chips or cracks. Any damage larger than 10mm directly in the driver’s line of sight (or 40mm elsewhere within the swept area of the wipers) will result in a fail. Make sure your wiper blades clear the screen effectively without smearing or tearing, and top up your windscreen washer fluid. Running out of washer fluid during an MOT is an automatic failure!

**3. Tyres and Tread Depth** The legal minimum tread depth across the central three-quarters of the tyre is 1.6mm. A quick way to test this is with a 20p coin: insert it into the main tread grooves. If the outer band of the coin is hidden, your tread is above the legal limit. Don't forget to check tyre pressures and inspect the sidewalls for bulges, cuts, or cracking—especially if you regularly navigate narrow lanes around West Harting.

**4. Dashboard Warning Lights** Turn your ignition on. All warning lights should illuminate briefly and then turn off. If lights such as the Engine Management, ABS, or Airbag warning lights stay lit while the engine is running, your vehicle will fail the test.

**5. Seatbelts and Mirrors** Pull every seatbelt out fully to check for fraying or damage, and make sure they click securely into place and retract smoothly. Ensure all mirrors are intact, secure, and clearly visible from the driver's seat.

### When Should You Book Your MOT? You can book an MOT up to one month (minus a day) before your current certificate expires while preserving your existing renewal date. Booking early gives you a safety cushion if repairs are needed before the deadline.
