Where should a flagging station be located in a work zone?

A flagging station should be located at the start of the taper in a work zone because this position is crucial for effectively alerting and directing approaching traffic as they transition into the altered roadway configuration. The taper is where the road begins to shift from the normal lane arrangement to a narrower or diverted path due to the work being conducted. Placing the flagging station at the start of the taper allows flaggers to give clear signals to drivers well in advance, ensuring that vehicles have adequate time to react, slow down, and navigate safely through the work zone.

This location maximizes visibility and provides a safer environment for both motorists and workers by clearly communicating the upcoming changes in road conditions before drivers enter the more confined sections of the work zone. By starting the warning and direction at the taper, this approach minimizes confusion and enhances overall safety in the area.
