The Convention on Road Traffic, commonly known as the Geneva Convention on Road Traffic, is an international treaty promoting the development and safety of international road traffic by establishing certain uniform rules among the contracting parties. The convention addresses minimum mechanical and safety equipment needed to be on board and defines an identification mark to identify the origin of the vehicle. The Convention was prepared and opened for signature by the United Nations Conference on Road and Motor Transport held at Geneva from 23 August to 19 September 1949. It came into force on 26 March 1952. This conference also produced the Protocol on Road Signs and Signals.
