The answer, explained
A STOP sign is an octagon with eight sides. Its instruction requires a complete stop.
The distinctive shape helps identify the sign's purpose alongside its red face and STOP lettering. At the intersection, use the marked stopping position where provided, then check and yield before continuing safely.
A common mistake
Recognizing the octagon but only slowing down does not satisfy the STOP instruction.
