Road Signs: A road signs diagram groups signs into categories like regulatory signs (e.g., STOP, YIELD), warning signs (e.g., curves ahead, deer crossing), guide signs (e.g., route numbers, destinations), and construction signs (e.g., detour, men at work). Symbols and colors are standardized for driver comprehensionred for prohibitive actions, yellow for caution, green for direction, and orange for construction. A complete chart is vital for driver education and international travel awareness.
