History: Early stop signs were actually yellow and black. In 1922, these colors were chosen because yellow was highly visible during the day. By 1954, red was standardized in the United States as the color for stop signs, in part because red conveys warning, danger, and the need to stop.
Shape: The octagonal shape was also standardized to allow drivers to recognize a stop sign even if the color faded.
Global Standardization: Many countries follow the Vienna Convention on Road Signs and Signals, making red stop signs common worldwide.
Red is associated with alertness and urgency, which is why traffic authorities have avoided alternative colors for regular stop signs.
