What is the primary role of a flagger?

The primary role of a flagger is to manage traffic and ensure the safety of workers in the work zone. This responsibility is critical because flaggers serve as a vital communication link between drivers and construction personnel. They use hand signals and flags to direct vehicles safely through or around work zones, minimizing the risk of accidents and ensuring that both motorists and workers can operate safely in a dynamic environment.

By effectively managing the flow of traffic, flaggers help reduce congestion and provide clear directions, which can prevent confusion for drivers and enhance the overall safety of the construction site. Additionally, their presence allows for the protection of workers who are on foot or operating machinery, as flaggers help establish designated safe pathways and alert drivers to ongoing work and potential hazards.

In contrast, responsibilities such as setting up work zone equipment, communicating with construction crews, or monitoring construction progress, while important, do not encompass the flagger's main focus on traffic management and safety.
