Which type of sign warns drivers of hazards ahead?

The type of sign that warns drivers of hazards ahead is a warning sign. These signs are specifically designed to alert drivers to potential dangers on the road, such as sharp curves, steep hills, pedestrian crossings, or changes in road conditions. The use of bright colors, such as yellow or orange, typically characterizes warning signs, which makes them easily noticeable and ensures that drivers can react appropriately to the hazards that may lie ahead.

In contrast, informative signs provide general information that helps drivers understand their surroundings but do not necessarily indicate hazards. Regulatory signs, on the other hand, communicate laws and rules that must be obeyed, such as speed limits or no entry signs. Directional signs are used to guide drivers toward specific destinations and do not convey any warning about potential dangers on the road. Hence, warning signs are crucial for enhancing road safety by preparing drivers for possible hazards they might encounter.
