Finding an Approved MOT Test Centre: The Blue Three-Triangle Sign

Recognising an approved centre

An MOT must be carried out at an approved MOT test centre. A garage without approval cannot lawfully test a vehicle, whatever other work it may offer. Drivers looking for a testing station therefore need to confirm that the premises hold approved status before booking.

The clearest way to recognise an approved centre is the blue sign displaying 3 white triangles. Only centres showing this sign can carry out an MOT. The sign is displayed at the premises and acts as a visible marker of approval, distinguishing a genuine test centre from an ordinary garage. Its presence confirms that the station is approved to conduct MOT tests.

The sign is specific in its design: a blue background with 3 white triangles. No other marking serves the same purpose, and the sign should be looked for directly at the testing station. Checking for the blue three-triangle sign is a simple way to identify an approved centre and to avoid premises that are not approved to carry out an MOT.

Heavy vehicles

Lorries, buses and trailers are not covered by the MOT scheme. They take an annual test instead, which is a separate inspection with its own standards and paperwork. The blue three triangle sign relates to MOT test centres, so it does not identify where these larger vehicles are tested. Operators looking for a site for an HGV, bus or trailer need to use the separate service rather than search for an MOT station.

A dedicated GOV.UK service lists test centres for HGVs, buses and trailers.

The annual test applies to goods vehicles, public service vehicles and trailers above the relevant weight limits. Testing stations for these vehicles are located across the country, and the GOV.UK service is the official route to find one. Operators can use it to identify a suitable centre before booking. The blue three triangle sign should not be relied on for these vehicles, as it marks MOT test centres only.

Checking where a vehicle was tested

The free GOV.UK MOT history service needs only the registration number. It shows each test result, the recorded mileage and when the next MOT is due. This makes it a quick way to review a vehicle's testing record before deciding whether to look further into where those tests took place.

Seeing where each test was done, for tests in England, Scotland and Wales, needs the 11-digit number from the V5C log book. The MOT history then lists the location of each recorded test, so past test centres can be identified and compared with the current record.

MOT history covers cars, motorcycles and vans tested since 2005, HGVs, trailers, buses and coaches since 2018, and Northern Ireland tests since 2017. Older records or vehicle types outside these dates will not show past test locations through the service.

Problems with a centre

Where a motorist believes a test centre has acted improperly, the DVSA cannot take action against that centre on the customer's behalf. Its role is limited to regulating the MOT scheme itself, not to pursuing individual complaints or recovering money. A driver who considers a centre has treated them unfairly must therefore look elsewhere for redress. The realistic options are to raise the matter with Trading Standards, to begin legal proceedings, or to report the centre to the police where the circumstances suggest a criminal offence may have been committed.

The DVSA can still be contacted about concerns relating to a testing station. Its MOT enquiries line is 0300 123 9000 and is open Monday to Friday, 8am to 5pm.

This division of responsibility matters when a complaint is being prepared.

Frequently asked questions

Where must an MOT be carried out?

Does the same service find centres for HGVs and buses?

No. A separate GOV.UK service finds test centres for HGVs, buses and trailers. Those vehicles take an annual test rather than an MOT.

What does the free MOT history service show?

The free GOV.UK MOT history service needs only the registration number. It shows each test result, the recorded mileage and when the next MOT is due. It covers cars, motorcycles and vans tested since 2005, HGVs, trailers, buses and coaches since 2018, and Northern Ireland tests since 2017.
