A warning sign is a traffic sign that alerts drivers to a potential danger or change in road conditions ahead, giving them enough time to slow down and react safely. These signs warn about hazards such as sharp bends, pedestrian crossings, slippery surfaces, merging traffic, animals on the road, or upcoming intersections. Their purpose is not to forbid or command anything, but simply to prepare drivers for situations that require extra attention.
