Warning signs are typically yellow because this color is universally recognized as a cautionary signal, indicating potential hazards or changes in road conditions. The bright yellow color is designed to grab the driver's attention and alert them to the need for increased awareness and caution. This is especially important in situations where road conditions may be unsafe, such as in construction zones, near sharp turns, or in areas with wildlife crossings.

In contrast, other colors like blue are often used for informational signs, red is reserved for stop signs and prohibitive signals, and green generally indicates directional guidance. Understanding the significance of different colors in road signage is crucial for safe driving and navigation.
