What color is typically used for construction zone signs?

In the context of road signs, orange is used for construction zone signs because it is highly visible and conveys a sense of caution and alertness to drivers. The color orange is specifically chosen to signal temporary conditions that require extra attention, such as roadwork or construction activities. This visibility is crucial for ensuring the safety of both workers and drivers in areas where hazards may be present.

Blue is generally used for informational signs, such as those indicating services or parking. Red typically signifies stop or prohibition commands, like stop signs or yield signs, while green is used for guiding information, indicating permitted movements or directions. Thus, orange stands out as the appropriate color to denote construction zones, highlighting the need for caution.
