DVSA have published the data that sits behind the heavy vehicles brake codes (DTP Numbers) used for Roller Brake Testing during their annual test.

Heavy Goods Vehicles (HGV), Public service Vehicles (PSV) and heavy trailers require a Roller Brake Test during their Statutory 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 example: 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) This spreadsheet was last updated March 2023
