General warning signs are typically what color?

General warning signs are typically yellow because this color is universally recognized as conveying caution and alertness. Yellow signs indicate that drivers should be prepared to respond to potential hazards ahead, such as curves in the road, pedestrian crossings, or changes in road conditions. This color choice signals to drivers that they need to pay close attention and adjust their driving behavior accordingly.

In contrast, green is commonly used for directional signs and information about distances to destinations, blue is associated with informational signs such as services available, and red signifies stop or prohibitory actions. Therefore, yellow is the most appropriate color for warning signs, effectively guiding drivers to be vigilant as they navigate roadways.
