Heavy Goods Vehicle Inspection: Horn Mobile App
The primary purpose of the Heavy Goods Vehicle Inspection: Horn
How does it work?
mobile app is to support staff in conducting the annual testing of vehicles. 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 inspection applies to all vehicles. Vehicles first used from 1 August 1973 must have a horn that produces a continuous or uniform sound. If vehicles are fitted with more than one horn only one has to work. If air horns are connected to the braking system of a vehicle the presenter should be made aware of the possible dangers as well as advising of any leaks from the air horns (there is no requirement to check if air horns operations deplete the braking system). If more than one horn control is fitted at least one must operate the horn.
