MOT
How Long Does an MOT Take? (And What Happens During One)
An MOT is not an all-day event. For most cars, the test itself takes under an hour — though waiting times, repairs, and how busy the garage is can extend your day significantly. Here's what to realistically expect.
1. The test itself: 45–60 minutes
A standard MOT for a passenger car takes approximately 45 to 60 minutes to complete. The tester works through a checklist of around 80 inspection points covering safety-critical systems. Some testers are faster; some cars (especially older vehicles with more to inspect carefully) take longer. Motorcycles take around 20–30 minutes.
2. What the tester actually checks
The MOT covers: lights and signalling (headlights, brake lights, indicators), brakes (pad thickness, disc condition, brake force balance), tyres (tread depth, condition, correct size), steering and suspension, seatbelts and airbag warning lights, exhaust emissions, windscreen (no major chips in the driver's line of sight), wipers and washers, horn, bodywork (no sharp edges), and the vehicle identification number (VIN). They do not check the engine internals, clutch wear, gearbox oil, or air conditioning.
3. Waiting vs dropping off
Most garages offer a 'wait while you watch' service — you sit in a waiting room while the tester works. Alternatively, you can drop the car off and collect it later. If you are waiting, budget at least 90 minutes from arrival to allow for the test plus any minor fixes (bulbs, top-up of washer fluid) that the garage may offer to handle on the spot to secure a pass.
4. What happens if your car fails?
If your car fails, the tester will give you a list of failures and advisory items. You have three options: authorise the same garage to carry out the repairs immediately (and get a free partial retest); take the car to another garage for repairs and return within 10 working days for a paid retest (currently around £23 for a class 4 vehicle); or drive the car home (if it has no 'dangerous' defects) and book a full retest elsewhere. A car with a 'dangerous' defect cannot legally be driven away at all.
