Flaggers should be placed at least how many feet from a construction site?

The correct distance for placing flaggers near a construction site is 100 feet. This distance is recommended to ensure adequate safety and visibility for both the flaggers and the drivers approaching the construction zone. By positioning flaggers at this distance, it provides a buffer allowing motorists enough time to react to any changes in traffic patterns or potential hazards that arise due to the construction activities.

Moreover, placing flaggers at 100 feet allows them to effectively communicate with drivers while ensuring their own safety from traffic. The Federal Highway Administration and many state guidelines recommend this distance to reduce the risk of accidents occurring too close to the work area.

Distances greater than 100 feet may lead to reduced effectiveness in managing traffic flow, as drivers may not recognize the construction area until they are too close. Conversely, closer placements can increase the risk of accidents as the flagger may not have sufficient time to signal drivers appropriately. Therefore, the guideline of 100 feet strikes a balance between safety and effective traffic management around construction sites.
