Where should flaggers stand to effectively warn drivers of approaching danger?

Flaggers should stand on the shoulder or in the closed lane to effectively warn drivers of approaching danger. This position allows them to be visible to oncoming traffic while still maintaining a safe distance from the moving vehicles on the roadway. By being on the shoulder or in a designated closed lane, flaggers can control traffic more effectively, ensuring that drivers are alerted to hazards ahead and can adjust their speed or direction appropriately.

Being on the shoulder also helps to provide a safe space for flaggers themselves, minimizing the risk of accidents with passing vehicles. Additionally, their placement in the closed lane can assist in directly guiding traffic away from potentially hazardous areas or incident scenes, ensuring a clear path for emergency responders while still alerting motorists to the situation ahead. This proactive stance enhances safety for everyone involved—both the flaggers and the drivers on the roadway.
