What do orange construction signs indicate?

Answer: B — Road work and construction zones ahead

Orange construction signs are specifically designed to alert drivers to road work and construction zones ahead. This color is universally recognized for indicating work zones where workers may be present, and where road conditions can change unexpectedly. These signs inform drivers to remain cautious, reduce speed, and be prepared for potential detours or other changes in road conditions. The distinction of orange for construction is a critical part of traffic signaling, as it helps to ensure safety for both drivers and road workers by drawing attention to potential hazards. In contrast, other signs serve different purposes; for example, signs indicating speed limit changes or traffic signal adjustments use different colors and symbols to convey different information pertinent to regular driving conditions.
