Construction signs are typically orange because this color is highly visible and easily recognizable, which is crucial for alerting drivers to upcoming road work or hazardous conditions. The use of orange is standardized in traffic signage to ensure a consistent message across various locations and jurisdictions. This specific color is chosen not just for its visibility, but also because it conveys a sense of caution and implies that drivers should slow down, be aware of changes in the roadway, or prepare for detours.

In contrast, green signs are generally used for directional and informational purposes, blue signs often indicate services or guidance, and yellow signs are mostly utilized for general warnings about potential hazards that are not related to construction. The distinct use of orange for construction zones helps maintain safety and awareness in areas where roadwork may affect the flow of traffic.
