What color are warning signs typically associated with traffic control?

Warning signs in traffic control are typically colored yellow because this color is universally recognized as a cautionary signal. Yellow is used to alert drivers to potential hazards or changes in road conditions ahead, such as curves, intersections, or areas where workers are present. The bright, highly visible nature of yellow ensures that it captures attention quickly, allowing drivers to prepare for any necessary actions, such as reducing speed or being more vigilant.

Green, red, and blue serve different purposes in traffic signage. Green is commonly used for directional signs and indicates the presence of upcoming destinations. Red is primarily reserved for stop signs and signals to convey prohibitory information, requiring drivers to halt. Blue is used to denote information related to motorist services, such as rest areas or gas stations. Each color in traffic control signage communicates specific information, making the standardized use of yellow for warning signs critical for effective traffic management and safety.
