What should you do if you see a flagger at a construction site?

Answer: B — Follow their signals and proceed with caution

When encountering a flagger at a construction site, it is essential to follow their signals and proceed with caution. Flaggers are trained professionals responsible for directing traffic to ensure the safety of both workers and drivers in potentially hazardous conditions. Their signals are specifically designed to provide clear instructions on how to navigate through or around the construction zone safely. By following their signals, you ensure that you are adhering to the established traffic regulations and reducing the risk of accidents. This action also helps maintain the flow of traffic, minimizing delays and disruptions. It's important to remain alert and attentive, as the area may contain risks such as workers, equipment, or other obstructions. Understanding the role of flaggers and responding appropriately enhances safety for everyone on or near the roadway, making it clear why this choice is the correct approach in such situations.
