What is the minimum number of flaggers required to perform basic flagging operations?

In basic flagging operations, the minimum requirement is one flagger. This is essential for ensuring that traffic is safely managed and directed through work zones. The flagger is responsible for communicating with drivers, using signals and signs to control the flow of traffic, and ensuring the safety of both workers and motorists. One flagger can effectively manage a straightforward situation, such as a temporary obstruction or a single lane closure, where their presence is sufficient to convey the necessary directions to oncoming traffic.

While additional flaggers may be required for more complex scenarios or larger work zones to enhance safety and efficiency, the fundamental standard for basic operations starts with one flagger.
