How to Prepare Your Car for Its MOT

Around one in three vehicles fail their MOT first time in the UK, and many failures are caused by simple, inexpensive issues — a blown bulb, worn wiper blade, or underinflated tyre. Spending twenty minutes checking your car before the test can make the difference between a pass and a return visit. Here is a practical checklist for drivers in Reading preparing for their MOT at /services/mot-testing.

Check all your lights

Switch on your headlights, sidelights, indicators, hazard lights, brake lights, reverse lights, fog lights, and number plate lights. Replace any failed bulbs — most cost a few pounds from a motor factors. Ask someone to press the brake pedal while you check the rear, or reverse up to a reflective surface such as a shop window at night.

Inspect tyres and tyre pressure

Use a tread depth gauge or the 20p test: insert a 20p coin into the tread groove — if the outer band of the coin is visible, your tread may be below the legal 1.6 mm limit. Check all four tyres plus the spare if your vehicle requires one. Look for bulges, cuts, and uneven wear. Set tyre pressures to the manufacturer's recommendation, usually found on a sticker inside the driver's door frame.

Test wipers, washers, and windscreen

Operate the washers and wipers. Replace blades that smear or skip. Examine the windscreen for chips and cracks in the driver's field of view — damage larger than 10 mm in the swept area may cause a failure. Small chips can sometimes be repaired affordably before they spread.

Top up fluids and check the fuel cap

Ensure washer fluid, engine oil, and coolant are at adequate levels. The tester needs enough fuel to run the emissions test — arrive with at least a quarter tank. Make sure the fuel cap fits securely; a missing or loose cap can trigger emissions problems on some vehicles.

Clear the cabin and boot

Remove heavy items from the boot and clear clutter from the cabin. The tester may need access to the handbrake, seat belt anchor points, and load-bearing areas. A tidy car also makes it easier for the examiner to carry out the inspection efficiently.

Address warning lights beforehand

An illuminated engine management, ABS, or airbag warning light will usually result in a failure. Book a diagnostics appointment at /services/diagnostics to identify and resolve the fault before your MOT. Fixing the underlying issue is almost always cheaper than failing, repairing, and rebooking separately.

Consider a pre-MOT inspection

If your car has not been serviced recently or you suspect worn brakes at /services/brake-repairs, book a pre-MOT inspection at Pickwell Autohub. Our technicians check the common failure points and advise what needs attention — giving you the option to approve repairs before the official test. Book both at /booking for a seamless experience at our RG1 or RG2 branches.
