What color is typically used for construction and maintenance signs?

• A. Red
• B. Blue
• C. Yellow
• D. Green

Answer: (C)

Construction and maintenance signs are typically colored yellow because this color is highly visible and easily recognizable in various lighting conditions. Yellow is associated with caution and alertness, effectively signaling drivers to remain vigilant and prepared for potential hazards or changes in roadway conditions. It is particularly effective in drawing attention, which is crucial in construction zones where workers may be present, and where temporary changes to the road layout or traffic patterns may occur. This emphasis on safety is vital in preventing accidents and ensuring that drivers are aware of ongoing construction activities. The other colors listed serve different purposes: red indicates stop or prohibition, blue conveys information about services, and green typically provides guidance or directional information. Thus, yellow is the appropriate choice for construction and maintenance signs as it conveys the necessary caution to road users.
