What should a flagger do if traffic patterns change?

When traffic patterns change, it is essential for the flagger to notify workers and adjust their positioning. This action is crucial for maintaining safety in the work zone. The flagger's role involves managing traffic effectively to protect both workers and the public. When changes occur, such as shifts in traffic flow or unexpected obstructions, the flagger must communicate these changes immediately to ensure that all personnel in the area are aware and can adapt accordingly.

Adjusting positioning helps to create a safer environment by allowing workers to be in optimal locations relative to the new traffic conditions. This proactive approach minimizes the risk of accidents and enhances the overall safety of the work zone, as workers will be prepared to respond to incoming traffic more effectively.

Other potential answers do not adequately support the safety of the work zone. Remaining stationary and observing does not address the immediate need for communication and adjustments. Signaling traffic according to previous patterns could mislead drivers, leading to confusion or accidents. Ignoring the change and continuing normal operations puts everyone at risk, as it disregards the new dynamics of the traffic flow. Thus, the most responsible and effective response to changing traffic patterns is for the flagger to notify workers and adjust their positioning.
