Is the stop sign the only octagon shaped sign?
We could consider only the front face of a stop sign, which would be an octagon (now, we are ignoring the thickness of the sign, and it has 8 sides). Stop signs are eight-sided. That makes them octagons, not hexagons (six-sided). In the United States, there is a pattern to the way road signs are shaped.
What does a octagon stop sign mean?
The octagon STOP sign means “Stop and give way to traffic on the major road”, whereas at roadworks someone is telling you to wait until they give the signal to proceed.
Why are stop signs octagons and not squares?

Why was the shape of the stop sign chosen?
The American Association of State Highway Officials (AASHO) saw a few key advantages to giving the stop sign its unique shape. First, the octagonal shape makes it easy for drivers traveling in the opposite direction to recognize the sign from the back, which helps prevent confusion at intersections, according to Reader’s Digest.
When was the Octagon added to a stop sign?
The octagon, in their view, was just under the circle. The color would come much later after many sign-letter combination trials, with the modern stop sign as we know it today not being unveiled until 1954, ironically after the death of Eno.
Why are stop signs on the opposite side of the road?
As Allstate further notes, “the octagonal shape makes it easy for drivers traveling in the opposite direction to recognize the sign from the back, which helps prevent confusion.” Ultimately, that adds up to fewer accidents, which is the whole point of the signs in the first place.
