Why Do Stop Signs Have Eight Sides?
When the first official stop sign did appear in Detroit, in 1915, it was small, white, and square, nothing like the red octagon we know today. But in 1923, a branch of Mississippi’s highway department suggested a change—what if a sign’s shape could denote the kind of hazard ahead? The logic was simple: The more sides a sign has, the more dangerous the upcoming stretch of road is.
Circles (which were considered to have infinite sides) designated the riskiest hazards, like railroad crossings. Octagons denoted the second most perilous hazards, like intersections. Diamonds signaled less-tricky stretches, and rectangles were strictly informational. We still use these parameters today, though no one knows why the nonagon drew the short stick.
