How Long Does an MOT Take? What to Expect at the Garage

By Salek Tyre & Mechanic · Ashford, TW15

A standard MOT test takes 45 to 60 minutes for most cars. It's one of those things that's easy to plan around once you know what's involved. Here's what the tester does during that time and what might cause it to take longer.

The typical MOT timeline

When you drop your car off, the tester works through a structured checklist that covers every aspect of the vehicle's roadworthiness. The DVSA specifies exactly what must be checked — the sequence is standardised across all approved test centres. Here's roughly how the time breaks down:

• Check-in and paperwork (5 min) — registration details confirmed, V5C checked if needed.
• Visual external inspection (5–10 min) — lights, number plates, bodywork, mirrors, windscreen, wiper blades, tyres.
• Under-bonnet check (5 min) — fluid levels, battery security, brake fluid reservoir, horn.
• Brake and suspension check on the ramp (10–15 min) — brake efficiency tested on a roller brake tester; underside checked for corrosion, steering joints, exhaust.
• Emissions test (5 min) — exhaust gases measured against DVSA standards for the vehicle's age and engine type.
• Headlight alignment check (5 min) — aim and beam pattern checked with a beam tester.
• Recording results and issuing certificate (5–10 min)

What makes an MOT take longer?

• Older vehicles — more complex underside inspections if there's corrosion or modifications to check.
• Failures requiring discussion — if the car fails, the tester will go through each item with you, which adds time.
• Combined MOT and service — if you've booked both, the service will be done separately after the MOT, typically adding 1–2 hours depending on the service type.
• Busy test bays — if the garage has multiple vehicles booked in, you may wait while a bay becomes free.

Should I wait at the garage or drop off?

For a standalone MOT, most people wait — 45–60 minutes is manageable. We have a waiting area at Salek and you're welcome to grab a coffee nearby on Feltham Road and come back. If you've also booked a service, dropping off and collecting later is usually more practical.

What do I need to bring?

For the MOT test itself, you just need the car. The tester doesn't need your V5C logbook (unless there's a discrepancy with the number plates), your service history, or any other paperwork. The MOT result is recorded digitally against your registration number — you'll receive a certificate, and the result is automatically updated on the DVSA database.
