A construction zone is indicated by...

• A. Orange sign.
• B. Yellow sign.
• C. Green sign.
• D. Red sign.

Answer: (A)

Orange is used for construction or maintenance work zones. This color is chosen because it stands out and tells you something temporary and potentially changing is ahead—like workers on or near the road, equipment, lane shifts, or other unusual traffic patterns. When you see orange, you should slow down, be alert, and follow any posted reduced speeds or directions from workers or signs. Yellow signs warn of general hazards, green signs give direction or permit information, and red signs mean stop or prohibition. So an orange sign best indicates a construction zone.
