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.

This traffic sign indicates a warning for a danger with no specific traffic sign. It's a general warning sign used when there is a hazard ahead that does not have its own dedicated warning sign. For examples: road accidents, flooded roads and roads blocked by fallen trees. It usually has a supplementary sign attached that tells drivers of what hazard to expect.
