The Convention on Road Signs and Signals, commonly known as the Vienna Convention on Road Signs and Signals, is a multilateral treaty that establishes an international standard for signing systems for road traffic, such as road signs, traffic lights and road markings.
The Convention was agreed upon by the United Nations Economic and Social Council at its Conference on Road Traffic in Vienna, Austria from 7 October to 8 November 1968. Thirty-one countries signed the Convention on the final day of the conference, and it entered into force on 6 June 1978. This conference also produced the Vienna Convention on Road Traffic, which provides complementary standardising of international traffic laws.
