Road signs in Switzerland and Liechtenstein generally conform to the 1968 Vienna Convention on Road Signs and Signals.[1]
Although Switzerland is not a member of the European Union, its road signs largely follow the general European conventions concerning the use of shape and color to indicate their function. Switzerland signed the Vienna Convention on Road Signs and Signals on November 8, 1968 and ratified it on December 11, 1991.[2] On March 2, 2020 Liechtenstein acceded to the Convention.
