Which type of sign is specifically designed to convey messages regarding safety on the road?

Warning signs are specifically designed to convey messages regarding safety on the road by alerting drivers to potential hazards or changes in driving conditions. They aim to prevent accidents by drawing attention to dangers such as sharp turns, slippery roads, or pedestrian crossings. These signs typically use bright colors, often yellow or orange, and varied shapes, like diamonds, to ensure they are noticed quickly and effectively by motorists.

Regulatory signs, while important for traffic control, focus on laws that must be followed, such as speed limits or stop signs. Informational signs provide guidance about locations and services, while directional signs assist with navigation and route finding. Each has its purpose, but warning signs hold a critical role in enhancing safety on the roads.
