Which of the following best describes the role of flaggers in train operations?

Flaggers play a crucial role in maintaining safety during train operations, especially in work zones. Their primary responsibility is to control the movement of trains in areas where workers are present, ensuring that both the workers and the trains are safe from accidents. Flaggers communicate critical information about train movements and keep an eye out for unauthorized personnel in the workspace. By signaling and directing trains, they help prevent collisions and manage risks effectively, thus safeguarding the lives of workers on or near the tracks. This role is essential to the overall safety protocols outlined in the Roadway Worker Protection program, emphasizing the importance of coordination and communication in environments where both human activities and train operations intersect.
