MOT pre-check checklist

MOT pre-check: the useful 10-minute walk-around

An MOT pre-check is not a substitute for the test, but it can catch obvious faults before the appointment. Work around the car methodically: tyres and wheels, lamps, glass and mirrors, washers and wipers, number plates, warning lamps, seat belts and obvious leaks. If something is safety-critical, repair it because the vehicle needs to be roadworthy, not simply to obtain a pass.

What to check before the MOT

Tyres and wheels

Measure tread at several points across all four tyres. For most cars and light vans the minimum is 1.6mm across the central three-quarters and around the complete circumference. Look for cuts, bulges, exposed cords, obvious under-inflation, unusual wear and damaged wheels. Where TPMS rules apply, a malfunction can also matter at MOT.

Lights, visibility and controls

With help if possible, operate dipped and main beam, indicators, hazards, brake lamps, rear lamps and fog lamps. Clean the lenses. Check the windscreen for damage in the swept area, make sure washers deliver fluid and wipers clear the screen effectively. Mirrors should be secure and usable.

Brakes, steering and warning lamps

Do not attempt a workshop brake test at home. Instead, note warning lamps, unusual pedal feel, pulling, grinding, steering play or new noises and arrange inspection. The MOT includes defined checks of brake condition and performance, steering, suspension and applicable electronic warning systems.

Number plates, belts and body condition

Make sure registration plates are secure, legible and not obviously damaged. Pull each seat belt out, check it latches and retracts, and remove clutter that prevents normal access. Doors, catches, seats, structure and other prescribed items are also part of the inspection.

What a pre-check cannot tell you

You cannot reproduce the full MOT on a driveway. Brake efficiency, underside condition, structural corrosion, suspension play, emissions and headlamp aim may need test equipment or access. A clean pre-check reduces avoidable surprises; it cannot guarantee a pass.

What to do next

Use this guide to prepare and ask better questions, not as a remote diagnosis. If a safety-critical defect is suspected, avoid unnecessary driving and arrange a competent physical inspection.
