Road sign design principles

Road sign design principles focus on clarity, visibility, and consistency to ensure drivers quickly understand messages and respond safely. Signs use simple shapes, meaningful symbols, and limiting text to avoid confusion. Colors are standardized (e.g., red for stops or prohibitions, green for directions) to convey meaning instantly. Font size and contrast improve readability from a distance or at high speeds. Proper placement and lighting ensure signs are visible in various weather conditions. Overall, effective road signs communicate important information efficiently, helping maintain safety and flow on the roads.
