Geneva Convention on Road Traffic
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. There is a European Agreement supplementing the 1949 Convention on Road Traffic, in addition to the 1949 Protocol on Road Signs and Signals, concluded in Geneva on 16 September 1950. Contracting parties. The Geneva Convention on Road Traffic was concluded in Geneva on 19 September 1949. The convention has been ratified by 101 countries. Since its entry into force on 26 March 1952, in signatory countries ("Contracting Parties") it replaces previous road traffic conventions, notably the 1926 International Convention relative to Motor Traffic and the International Convention  relative to Road Traffic, and the Convention on the Regulation of Inter-American Automotive Traffic in accordance with Article 30 of the Convention. Many of the contracting parties have also ratified the newer convention the Vienna Convention on Road Traffic of 1968. In signatory countries of the 1968 Vienna Convention, this replaces previous road traffic conventions including the Geneva Convention on Road Traffic, in accordance with Article 48 of the Vienna Convention. Cross-border vehicles. One of the main benefits of the convention for motorists is the obligation on signatory countries to recognize the legality of vehicles from other signatory  countries. The following requirements must be met when driving outside the country of registration: In practice, the requirement to display a distinguishing sign as defined in the Geneva Convention on Road Traffic is waived between some countries, for example within the European Economic Area, for vehicles with registration plates in the common EU format (which incorporates the distinguishing sign into the registration plate). This is also possible in countries party to the newer Vienna Convention on Road Traffic, and between Canada, the United States, and Mexico (where the province, state, or district of registration is usually embossed or surface-printed  on the vehicle registration plate). International Driving Permit. The Geneva Convention on Road Traffic is one of three conventions that governs International Driving Permits. The other two are the 1926 Paris International Convention relative to Motor Traffic and the 1968 Vienna Convention on Road Traffic. When a state is contracting to more than one convention, the newest one terminate and replace previous ones in relation between those states. The 1949 Convention's description of a driving permit and international driving permit are located in Annexes 9 and 10. The 1949 Geneva Convention states that an IDP remains valid for one  year from the date of issue.
