What is the focus of the 'How to Flag' section in the course?

• A. To teach proper flagging techniques and communication methods
• B. To calculate lane closures
• C. To install signage
• D. To manage traffic signals

Answer: (A)

The focus is on teaching how to safely flag traffic and communicate with motorists and the work crew. It covers proper flagging techniques—holding flags or paddles, body stance, signaling motions, and maintaining high visibility—and the standard communication methods used in flagging operations, such as clear hand signals and whistle commands to stop, slow, or proceed. This combination ensures flaggers can control traffic effectively while keeping themselves and workers protected in the work zone.

Tasks like calculating lane closures belong to planning and sequencing of traffic control, installing signage is about placing warning and regulatory signs, and managing traffic signals deals with operating signal timing and phasing. So the section centers on flagging techniques and communication methods.
