This series contains policy files relating to all aspects of vehicle safety, including motor vehicle construction and use regulations (dealing with, for example, tyres, brakes, headlights and seat belts); vehicle testing and inspections; the approval of motor vehicles, equipment and parts; speed limits; and standards for the construction and use of goods vehicles, public service vehicles and hovercraft. Some files were re-registered from the VR and VRT series.
The series also contains papers concerning a 1954 regulation requiring all pedal cyclists to maintain their brakes.
The VS files commenced in 1968, replacing the VR (Vehicle Regulation) series (otherwise in MT 165) which had been created in 1962 and which, in turn, replaced the construction and use of vehicles files in the VRT (Vehicle Regulations and Taxation) series (otherwise in MT 99).
