Which tool is commonly used for directing traffic in work zones?

Flagger paddles are an essential tool for directing traffic in work zones, serving as a visual cue for drivers to determine when to stop or proceed. These paddles typically feature bright colors and straightforward messages, such as “Stop” or “Slow,” which are easily recognizable even from a distance.

Their effectiveness lies in the direct communication they provide from a human flagger stationed at the work zone, ensuring that traffic flow is managed safely and efficiently. The presence of a flagger using a paddle can respond dynamically to the situation, adapting to changing conditions and ensuring the safety of both workers and drivers.

Other tools mentioned, such as traffic signals, speedometers, and electronic message boards, serve different purposes in traffic management. Traffic signals are typically used at controlled intersections rather than work zones. Speedometers provide information on vehicle speeds but do not direct traffic movement. Electronic message boards relay information but do not provide immediate stop or go instructions, which are crucial in the context of work zone traffic control. Thus, flagger paddles are specifically designed for this role and are integral in maintaining safety in work zones.
