Most MOT tests take between 45 minutes and one hour to complete. However, the total time you'll spend at the garage can vary depending on how busy they are, whether your vehicle passes the test, and if any repairs are needed.
Understanding how long an MOT takes can help you plan your day and avoid unnecessary delays.
Before attending your test, it's also worth checking your vehicle's previous MOT history. You can use our free MOT History Checker to view previous MOT results, advisories, mileage records and failures.
How Long Does the MOT Test Itself Take?
For most cars, the inspection takes approximately:
- 45 to 60 minutes for a standard passenger vehicle.
- Slightly longer for larger vehicles or if additional checks are required.
The MOT follows a fixed inspection carried out by an authorised tester. They examine a range of safety and environmental items but do not dismantle the vehicle.
Why Might It Take Longer?
Several factors can increase the amount of time your vehicle stays at the garage:
- The garage has a busy schedule.
- Your vehicle requires further investigation.
- Minor repairs are carried out immediately.
- Replacement parts need to be ordered.
- The vehicle fails its MOT and requires repairs before a retest.
Some garages offer while-you-wait appointments, while others may ask you to leave the vehicle for several hours.
What Does an MOT Include?
During the inspection, the tester checks many safety-critical components, including:
- Lights and indicators
- Brakes
- Tyres and wheels
- Steering and suspension
- Windscreen and wipers
- Mirrors
- Seatbelts
- Exhaust emissions
- Vehicle structure

What Happens If Your Car Passes?
If your vehicle meets the required standards, you'll receive a pass certificate.
You may still receive advisory notices, highlighting parts that are worn or likely to need attention before your next MOT.

What Happens If Your Car Fails?
If your vehicle fails, you'll receive a list of defects explaining why.
Depending on the severity of the faults:
- Minor defects won't cause a failure.
- Major defects result in an MOT failure.
- Dangerous defects mean the vehicle should not be driven until repaired.

Frequently Asked Questions
Can an MOT take less than 30 minutes?
Usually not. Most MOT inspections take at least 45 minutes because every required safety check must be completed.
Can I wait while my MOT is carried out?
Many garages allow customers to wait on-site, although this depends on available space and appointment scheduling.
What if my car fails?
The garage will provide a list of defects that need to be repaired before the vehicle can pass its MOT.
Does an MOT include servicing?
No. An MOT checks whether your vehicle meets the legal minimum safety and environmental standards. A service is separate and involves maintenance such as changing oil, filters and inspecting wear items.
Final Thoughts
Most MOT tests are completed within an hour, but it's sensible to allow extra time in case repairs are required or the garage is particularly busy.
Checking your vehicle's previous MOT history before your appointment can also help you identify recurring advisories and prepare for any likely repairs.
