Most drivers instantly recognize the iconic red, octagonal stop sign. It’s a universal symbol of caution and control, commanding attention at intersections across the U.S. and beyond. That bold red background with crisp white lettering isn’t just for looks—it’s a carefully chosen design governed by the Manual on Uniform Traffic Control Devices (MUTCD).
