Heavy Vehicle Brake code (DTP number) database

Heavy Goods Vehicles (HGV), Public service Vehicles (PSV) and heavy trailers require a Roller Brake Test during their Stautory Test (MOT). The computer controlled Roller Brake Tester (RBT) knows how to test the individual vehicles/trailers because a brake code or DTP number is entered. The DTP number contains all the information for the vehicle being tested, for eample: Axle weights Design Gross Vehicle and Train weights Make, Age, etc . This spreadsheet gives all the information that sits behind DTP numbers allocated to HGV only (PSV and Trailers are different) For PSV brake codes, please go to: https://view.officeapps.live.com/op/view.aspx?src=https%3A%2F%2Fassets.publishing.service.gov.uk%2Fmedia%2F5dfa046040f0b6093fe76083%2Fwork-out-psv-brake-code.xlsx&wdOrigin=BROWSELINK (the excel worksheet may need to be opened in desktop app to work correctly) Note: The information entered into this spreadsheet may be slightly different to that given to the DVSA when the PSV was entered into service - therefore the code may be slightly different to that used at MOT. Best practice would be to take note of the code from the MOT brake printout. This spreadsheet was last updated June 2024
