What color are warning signs typically?

Warning signs are typically yellow to alert drivers to potential hazards or changes in conditions that may require caution. The bright yellow color is highly visible and is easily recognized by drivers, making it an effective choice for conveying important safety messages. This color association helps ensure that drivers can quickly identify warnings about upcoming road conditions, such as curves, intersections, pedestrian crossings, and construction zones.

Other colors used in traffic signs serve different purposes: for example, red signs indicate prohibition or stop, while blue signs often convey information regarding services or points of interest. Green signs typically provide directional guidance or indicate permitted actions. Therefore, yellow is the established standard for warning signs, enhancing safety on the road by promoting awareness of potential hazards.
