What does an orange construction sign indicate?

Answer: B — Road work or construction ahead

An orange construction sign indicates road work or construction ahead because the color orange is specifically designated for temporary traffic control in construction zones. This color is used to alert drivers to changes in road conditions, such as lane closures, road maintenance, or other activities that may affect the flow of traffic. The purpose of these signs is to ensure safety by preparing drivers for potential hazards and encouraging them to navigate through the area with caution. In contrast, other signs with different colors or designs indicate different situations, such as accidents or speed limits, but orange uniquely signifies that drivers should be attentive to construction activities.
