A flagger ahead sign is a traffic sign that warns drivers of a flagger or construction worker directing traffic ahead. The sign is typically used in construction zones or areas where roadwork is being done and traffic needs to be controlled manually. It is usually marked with a symbol of a person holding a flag, indicating that drivers should slow down and follow the flagger's directions. The purpose of the sign is to ensure the safety of both workers and drivers by preparing them for potential changes in traffic flow.
