How should flaggers apply their training when controlling traffic?

• A. Using professional judgment to adapt signaling and positioning for safety.
• B. Strictly following a fixed script regardless of conditions.
• C. Ignoring vehicle behavior and focusing on speed.
• D. Confining to one standard procedure.

Answer: (A)

Flaggers must apply training by using professional judgment to adapt signaling and positioning for safety. Training provides the standard signals and the knowledge of where to stand and how to move, but the best practice is to read the specific site—traffic speeds and volumes, road geometry, weather and visibility, time of day, and worker location—and adjust signaling and positioning to keep motorists and workers safe. For instance, on a busy road with limited sight Distance, you may position yourself and use signals so approaching drivers can clearly see you well in advance, and you may increase your visible presence in poor weather or at night. Rigidly sticking to a fixed script or ignoring vehicle behavior undermines safety, because conditions change and drivers must be guided with clear, unexpected-ish cues and sufficient reaction time.
