Which sign is posted in a work zone to give advance warning of lane closings, construction areas, and workers ahead?

• A. Yellow, square-shaped signs
• B. Neon green, hexagon-shaped signs
• C. Orange, diamond-shaped signs
• D. Red, pentagon-shaped signs

Answer: (C)

Orange, diamond-shaped signs are used in work zones to give advance warning of lane closings, construction areas, and workers ahead. The orange color signals temporary traffic control due to construction, while the diamond shape is the universal warning sign, alerting drivers to slow down, stay alert, and follow any changes in traffic patterns such as lane shifts or detours. Other options don’t fit because yellow square signs aren’t the standard work-zone warning, neon green signs are used for different safety messages (like pedestrian or school areas), and red pentagon shapes are associated with other types of warnings, not construction zones.
