What does an orange sign typically indicate?

Answer: B — Road construction or maintenance ahead

An orange sign is commonly used to indicate road construction or maintenance ahead. This color is specifically chosen to convey warnings about temporary changes in the roadway or traffic conditions, such as lane closures, detours, or the presence of construction workers. The use of orange helps to enhance visibility and alert drivers to be cautious in these areas, ensuring everyone's safety. In contrast, other options represent different warning signs with distinct colors: danger signs, often in yellow, communicate potential hazards; speed limit changes are typically shown with white or regulatory signs; and street closures are indicated with different signage that may not be orange. Thus, the association of orange specifically with construction or maintenance highlights its role in alerting drivers about specific roadway conditions.
