• B. Flaggers enforce fines on violators.
• C. Flaggers only mark lanes but do not direct traffic.
• D. Flaggers work only during nighttime.

Answer: (A)

Guiding traffic through a work zone safely is the core role of a flagger. They actively direct vehicles and pedestrians using standardized signals, such as stop/slow paddles, flags, hand signals, and sometimes a whistle or radio. The goal is to create a predictable path, give workers space, and reduce the risk of collisions or injuries by controlling the flow and speed of traffic as people and equipment operate nearby. A flagger positions themselves to be clearly visible, communicates clearly with drivers, and coordinates with other flaggers and devices in the work zone to maintain a safe pace and lane arrangement. They do not enforce fines or law, and their duties involve directing traffic rather than merely marking lanes or operating only at night—flagging can occur during the day or night depending on conditions.
