What does an orange construction sign indicate?

Answer: B — Road work or construction is ahead; use caution

An orange construction sign indicates that there is road work or construction ahead, prompting drivers to use caution. These signs are specifically designed to alert motorists about temporary hazards that can arise in construction zones, such as uneven road surfaces, workers present, and equipment in the vicinity. The color orange is universally recognized for construction and maintenance activities, making it an important signal for drivers to remain alert and reduce their speed to navigate safely through the work area. In contrast, road closure signs typically emphasize a complete closure rather than directing attention to work being conducted, while traffic signal changes and speed limit changes are indicated by different colors and designs. Hence, the presence of the orange sign specifically warns drivers regarding active construction, which is essential for ensuring both the safety of the motorists and the workers on-site.
