What do traffic signs using the color yellow typically indicate?

Traffic signs that use the color yellow are designed to convey warnings to drivers and pedestrians about potential hazards or changes in road conditions. Yellow signifies caution, warning drivers to be alert and prepared for situations such as sharp curves, pedestrian crossings, or the presence of school zones. This color grabs attention and signals that caution is needed, helping to enhance safety by informing road users of conditions that require extra vigilance.

In contrast, other colors have specific meanings. For example, regulatory signs, which indicate laws or regulations, typically use red or white colors, while informational signs usually feature green or blue hues. Construction signs are often orange to draw attention to active work zones, clearly distinguishing them from general caution signs. This establishes yellow as the color specifically associated with warnings and alerts in the traffic signage system.
