How Long Does an MOT Test Take?

How Long Does an MOT Test Take?

A standard car MOT usually takes around 45 minutes to an hour. That is the time for the inspection itself, when a tester works through the full list of safety and emissions checks using specialist equipment such as brake rollers and a headlight beam setter.

The exact time depends on the vehicle and the garage. A small car with no issues can be done quickly, while a larger vehicle or one that needs closer inspection may take the full hour. If you want to know exactly what the tester is working through in that time, our guide on What an MOT Checks lists every item checked.

It is worth separating the test from any repairs. The 45 to 60 minute figure is the inspection only. If your car fails and needs work to pass, that repair time is extra and depends on the fault and the parts involved. Our overview on What Is an MOT explains how the test fits into keeping your car legal.

What Can Make an MOT Take Longer

Several things can stretch the time beyond the usual hour. None of them change the inspection itself, though they affect how long your car is with the garage.

If your car does fail, the repair time varies a lot. A simple fix such as a bulb or a wiper blade can be sorted in minutes, while a part that has to be ordered in can mean a wait of a day or more. Our guide on When Your Car Fails an MOT explains what happens next after a failure.

How Long Does a Retest Take?

A retest is usually much quicker than the original test. If your car fails and you have it repaired then retested within ten working days at the same centre, only the items that failed are checked again rather than the whole car. That partial retest can take just a few minutes for a small fix.

Leaving the car at the garage for repair and retest is the smoothest route. It often means the retest is free. Our guide on MOT Retest Rules sets out the retest window and the rules in full, so you know what to expect if your car does not pass first time.

How to Plan Around the Test

A little planning makes the test painless. Because the inspection takes around an hour, you can often wait at the garage or use the time nearby. If you are combining the MOT with a service, plan for a longer visit or a drop off.

Combining jobs is a common way to save a trip. Our guide on MOT and Service Price explains how an MOT and service fit together in one visit and what the combined time looks like.

Why the Test Takes Around an Hour

It can seem a long time to check a car you drive every day, yet the hour is well spent. An MOT is a detailed inspection of everything that affects safety and emissions, covering the brakes, steering, suspension, lights, tyres, seatbelts, the exhaust and the structure of the car. Each group holds several individual checks, so the list is longer than it first appears.

Some checks also need equipment rather than a quick glance. The brakes are measured on a rolling road, the headlight aim is set with a beam machine then the emissions are read from the exhaust. Doing these properly takes time, which is exactly why a thorough test protects you and other road users. A rushed test would not be a real one, so the hour is a sign the job is being done right.
