===US mandate, international adoption===
The MUTCD stop sign was already widely deployed in the United States when the use of other types of stop signs was eliminated in 1966.<ref name="signalfan" /> In 1968, this sign was adopted by the [[Vienna Convention on Road Signs and Signals]] as part of [[United Nations Economic Commission for Europe]]'s effort to standardize road travel across borders. The Convention specifies that '''{{Smallcaps|stop}}''' be written in English or the national language, and also allows a circular sign with red legend.
