What is checked in an MOT? The complete list
Updated September 2026
An MOT is a yearly safety and emissions inspection. The tester follows the DVSA inspection manual and checks the parts of your car that keep you and other road users safe. It is not a service, so the engine, clutch and gearbox condition are not examined.
Outside the car
- Lights, indicators, hazard lights and headlamp aim
- Number plates: condition, legibility and correct characters and spacing
- Tyres and wheels: tread depth, cuts, bulges, size and type
- Wipers and washers, and damage to the windscreen in the driver's view
- Mirrors, doors, bonnet catch and boot security
- Body and structure: no excessive corrosion or sharp edges in specific areas
- Towbar (if fitted) and its electrics
Inside the car
- Seatbelts: condition, operation and security
- Seats: secure, and the driver's seat adjusts
- Horn
- Dashboard warning lamps such as ABS, airbag and power steering
- Speedometer and odometer
Under the car and bonnet
- Brakes: performance, condition, pipes and hoses
- Steering and suspension components
- Exhaust system: security, leaks, and the emissions test (petrol, diesel and hybrid)
- Fuel system: leaks, and the fuel cap seals
- Vehicle identification number (VIN) present and legible
- Electrical wiring and battery security
What an MOT does not check
The condition of the engine, clutch or gearbox is not part of the test. That is why many drivers book a service at the same time as the MOT.
