What color are warning signs typically?

Warning signs are typically yellow because this color is universally recognized as a cautionary indication. Yellow alerts drivers to potential hazards or changes in the roadway, such as curves, construction zones, or pedestrian crossings. It stands out against the natural landscape, ensuring that drivers notice the signs easily and can take appropriate action to maintain safety. This color-coding helps facilitate understanding of road conditions and enhances driver awareness, making it a crucial choice for effective communication on the roads.
