Heavy Goods Vehicle Inspection: Vehicle to Trailer Coupling Mobile App
The primary purpose of the Heavy Goods Vehicle Inspection: Vehicle to Trailer Coupling mobile app is to support staff in conducting the annual testing of vehicles.
How does it work?
The app is useful to those responsible for the maintenance of large commercial vehicles so that they remain well informed on the current minimum legal standards for roadworthiness. It must be emphasised that these are minimum acceptable standards, which do not necessarily allow for further deterioration when the vehicle is in service.
This examination applies to all vehicles fitted with a trailer coupling (at the front or at the rear) and to all trailers. This inspection also covers fifth wheel couplings mounted on converter dollies. If the vehicle has a coupled trailer it must not be uncoupled. To check for relative movement between the tractor and trailer apply the trailer brakes and ask the driver to lightly shunt the tractor back and forth.
