MOT Basics

How long does an MOT take?

A standard car MOT takes around 45 to 60 minutes — but if you're waiting at the garage there's often more time involved than just the test itself.

Typical duration for a car

The test itself is a fixed set of checks carried out in a set sequence. For most standard passenger cars, it takes between 45 minutes and one hour from the moment the tester starts work on your vehicle.

Typical MOT duration — standard car
45–60 min
From when the tester begins work. Allow extra time if you're waiting at the garage, particularly at busy periods.

What happens during those 45–60 minutes?

The DVSA lays out exactly what must be checked, and testers work through the list in a structured order. Here's a rough breakdown of where the time goes:

~5 min
Initial checks
Registration plate, VIN, lights, horn, wipers, and washers — all done before the car goes on the ramp.
~10 min
Underbody inspection
The car is lifted on a ramp so the tester can check the underside — steering, suspension, brakes, exhaust, and fuel system.
~10 min
Brake test
The car is driven onto a roller brake tester. Each wheel's braking force is measured and compared against DVSA standards.
~10 min
Emissions test
A probe is inserted into the exhaust to measure emissions. Petrol and diesel cars are tested differently. This must be done with a fully warm engine.
~15 min
Remaining checks & paperwork
Tyres, bodywork, mirrors, seatbelts, and any remaining items. The tester then records results and issues the certificate or failure notice.

What can make it take longer?

Waiting time — If the garage is busy and your car can't go in straight away, add that waiting time on top. An 8am first-slot booking is usually the fastest in and out.

Advisories — If the tester finds items to note as advisories, they take extra time to document them properly in the DVSA system. A clean pass is quicker than one with several advisories.

A failure — If your car fails, the tester still needs to complete all the checks and record every failure item. Then if you want to stay for repairs, you could be there for the rest of the day.

Older or unusual vehicles — Classic cars, imports, or modified vehicles sometimes need more time due to unusual configurations or hard-to-access components.

Tip: If you need to be somewhere, book the first slot of the day and ask the garage for an estimated time when you drop off. Most are happy to call you when it's done rather than having you wait on site.

How long if my car fails?

If your car fails its MOT and you choose to have repairs done at the same garage, the overall time depends entirely on what needs fixing. Minor work like a bulb replacement might add 15 minutes. More significant repairs — a worn tyre, a brake fault, an emissions issue — could mean leaving the car and collecting it later. Always ask for an estimate before agreeing to any repair work.
