What is the primary function of an Advanced Mobile Flagger (AMF)?

The primary function of an Advanced Mobile Flagger (AMF) is to verbally warn Rail Vehicle Operators of Roadway Workers on the track ahead. This role is crucial in maintaining safety on or near tracks where workers may be present, as it ensures that operators are alerted to potential hazards and can take appropriate action to avoid accidents. The AMF serves as an essential communication link between the workers on the ground and the operators of trains or other rail vehicles, helping to prevent situations that could lead to injury or fatality.

The other choices, while related to railway operations, do not directly pertain to the responsibilities of the AMF. Managing train schedules is an operational task that focuses on timing rather than worker safety. Overseeing financial aspects is unrelated to the AMF's primary function, which is centered on safety and communication. Conducting safety inspections of the tracks is a distinct role typically assigned to track inspectors or maintenance personnel, rather than a flagger focused on worker protection and alerting operators.
