What color is primarily used for warning signs related to construction?

The primary color used for warning signs related to construction is orange. This color is specifically chosen because it grabs attention and signals caution to drivers and pedestrians. Orange is widely recognized as a color that indicates construction activities or road maintenance work, helping to alert road users to potential hazards in the area.

Orange signage provides a strong contrast against many outdoor environments, ensuring that it stands out and can be easily seen, even from a distance. Its use is a standard practice in traffic management and helps to maintain safety during construction by notifying individuals of altered traffic patterns or road conditions.

In contrast, red is typically used for stop and prohibitory signage, green is associated with directional signs or indicating permitted actions, and blue is used for informational signs related to services. This differentiation in color coding is crucial for effective communication and safety on the roadways.
