Road Traffic Act 1930
The Road Traffic Act 1930 made provision for, amongst other things, "the regulation of traffic on roads and of motor vehicles and otherwise with respect to roads and vehicles thereon" and "the protection of third parties against risks arising out of the use of motor vehicles".
It had considerable impact not just on roads but also on drivers, detailing driving offences, introducing insurance, and providing a Highway Code. It empowered local authorities to issue orders for the closure of roads to allow repairs or construction work and to erect traffic signs, create refuges and subways for pedestrians, provide parking places, and run their own bus services.
The Act came into force on 1 August 1930.
