Which color is used for warning signs in traffic?

Warning signs in traffic are primarily colored yellow. This color is chosen for its high visibility and ability to grab drivers' attention, particularly in situations that require caution. Yellow warning signs alert drivers to potential hazards ahead, such as sharp turns, pedestrian crossings, or road construction. The importance of using yellow for warning signs lies in its psychological effect, as it is associated with caution and safety, prompting motorists to approach upcoming situations carefully.

Other colors used in road signage serve different purposes. Red is typically reserved for stop signs and prohibitory signs, which indicate that drivers must stop or are restricted from certain actions. Green is generally used for informational signs, indicating direction or distances, while blue is associated with services and amenities for drivers, such as rest areas or gas stations. By understanding the specific use of each color in traffic signs, drivers can navigate the roadways more safely and effectively.
