Enter MOT test vehicle specific information (VSI)
How to enter vehicle specific information (VSI) into the MOT testing service.
Update vehicle specific information (VSI)
When a class 3, 4, 5 or 7 vehicle is registered for test you’ll be presented with the nominal vehicle weight for brake calculation purposes.
This can be altered if either:
- you’re using a brake tester which has an incorporated vehicle weighing facility
- the nominal presented brake weight is obviously incorrect
Nominated testers (NTs) should refer to manufacturer or other reliable data (eg brake test weight charts, technical manuals etc) when a vehicle weight isn’t made available.
A decelerometer test should be carried out and the figures recorded in the new service if a vehicle weight isn’t made available and NTs can’t check a brake weight from a reliable alternative source.
Other VSI isn’t shown in the service. This is because the MOT trade told the Driver and Vehicle Standards Agency (DVSA):
- they didn’t use it
- it wasn’t reliable
- they preferred to use other data services
Instead, NTs should refer to manufacturer or other reliable data if information is required on things like:
- anti-lock braking systems
- electronic parking brake systems
Information on emissions limits are held on the exhaust gas analyser and within the latest edition of the ‘In service exhaust emission standards for road vehicles: 18th edition’.
