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)
