The rapid growth of international road travel after World War II created a pressing need for standardized rules governing vehicle safety, equipment requirements, and identification across national borders, prompting the United Nations to convene a dedicated conference on road and motor transport.
The UN Conference on Road and Motor Transport met in Geneva from 23 August to 19 September 1949, producing the Convention on Road Traffic. The treaty established uniform minimum mechanical and safety equipment requirements for vehicles and defined a standard identification mark indicating a vehicle's country of origin.
The Convention entered into force on 26 March 1952 and was later supplemented by a European Agreement in 1950. It also prompted the companion Protocol on Road Signs and Signals, collectively providing the legal infrastructure for safer and more consistent international road transport.
Political Outcome
Treaty adopted and opened for signature; entered into force 26 March 1952, establishing uniform international road traffic rules.
