We have the Mississippi Valley Association of State Highway Departments to thank for the stop sign’s iconic shape. In 1923, the association developed an influential set of recommendations about street-sign shapes whose impact is still felt today. The recommendations were based on a simple, albeit not exactly intuitive, idea: the more sides a sign has, the higher the danger level it invokes.
Although all English-speaking and many other countries use the English word stop on stop signs, some jurisdictions use an equivalent word in their primary language instead of or in addition to it.
"Both stop and arrêt are considered valid French words and the Office québécois de la langue française (OQLF) notes that the use of "stop" on stop signs is attested in French since 1927"
