In a two-flagger setup, what is essential for coordination?

• A. The flaggers must stand on opposite sides of the road.
• B. They must never communicate.
• C. They must rotate leadership every 30 seconds.
• D. The lead flagger coordinates signals and the other flagger can see them or use two-way radios.

Answer: (C)

In a two-flagger setup, coordination hinges on clear, synchronized signaling between the two people. The lead flagger is the one who coordinates the signals, and the other flagger must be able to see those signals and respond accordingly, or stay in touch using two-way radios. This arrangement creates a reliable and predictable flow of traffic, because the instructions come from one point of reference and are watched or communicated in real time. Using two-way radios helps maintain coordination when visibility is limited or distance increases, keeping both flaggers in sync even if direct sight isn’t perfect. Rotating leadership every 30 seconds would introduce constant changes in who is giving signals, leading to confusion and unsafe conditions. The important takeaway is that a clear lead signaling the actions, with the other flagger able to observe those signals or communicate via radio, is what keeps the operation coordinated and safe.
