What is the background color for work area signs?

• A. Yellow
• B. Orange
• C. Red
• D. White

Answer: (B)

Work area signs use an orange background to clearly signal temporary conditions caused by construction or maintenance. The bright orange stands out to drivers and indicates that traffic rules or patterns may be temporarily altered, so you should slow down, follow posted directions, and watch for workers and equipment. The other colors have different meanings—yellow warns of general hazards ahead, red indicates stop or prohibition, and white conveys regulatory information—so orange is the color specifically reserved for construction and work zones.
