At an MOT, a tester inspects your car against government safety and emissions standards - it takes about 45 to 60 minutes and ends in a pass or fail, plus any advisories. No parts are changed; it's an inspection only. You wait or drop the car off, and the result is logged to the DVSA database (visible afterwards on RegScan).
How long does it take?
A standard car (Class 4) MOT takes roughly 45 to 60 minutes. If the centre is busy you may be asked to leave the car for a few hours. Repairs and a retest, if needed, take longer.
What the tester checks
The tester works through set items against DVSA standards, without dismantling the car:
- Lights - headlights, indicators, brake lights, reflectors and aim
- Brakes - condition, performance and balance (often on a roller machine)
- Tyres and wheels - tread depth, condition and correct size
- Steering and suspension - wear and operation
- Seatbelts - condition and that they latch
- Windscreen, wipers and washers - view and cleaning
- Exhaust and emissions - noise and pollutant levels
- Body and structure - corrosion in key areas, sharp edges
- Number plates, horn, mirrors and VIN
What they don't check
An MOT does not assess engine, clutch or gearbox condition, or general mechanical reliability - that's what a service is for. It's purely a safety and emissions inspection at a point in time.
Understanding the result
- Pass - you get a certificate; any advisories are noted for you to monitor.
- Fail - caused by a Major or Dangerous defect; must be repaired and retested. A dangerous defect means you must not drive it away.
After the test
The result is recorded against your registration in the DVSA MOT history within minutes. You can view it - along with past results, mileage and recurring advisories - free on RegScan. Check your vehicle.
