Traffic Commissioners
The traffic commissioners are responsible for the licensing and regulation of the operators of heavy goods vehicles, buses and coaches, and the registration of local bus services in Great Britain.
The Road Traffic Act 1930 divided Great Britain into twelve traffic areas: Metropolitan, Northern, Yorkshire, North-Western, West Midland, East Midland, Eastern, South Wales, Western, Southern, South-Eastern and Scottish. (The Southern traffic area was discontinued in 1933 and its responsibilities split between the Western and South-Eastern areas).
