What color combination typically identifies warning signs?

The combination of yellow and black is the standard for warning signs in most traffic systems. This color pairing is specifically designed to capture the driver's attention and convey caution. Yellow is a bright, eye-catching color that signifies a warning, while black serves as a bold contrast, enhancing visibility. As a result, warning signs effectively communicate important information about potential hazards ahead, such as curves, pedestrian crossings, or road construction. This visual strategy ensures that drivers can quickly recognize and react to safety risks while on the road.
