Why is additional lane space taken in block positioning?

Taking additional lane space in block positioning is primarily aimed at creating an adequate buffer space between responders who are "feet on the street" and the moving traffic. This buffer is crucial for ensuring safety, as it helps to protect firefighters, paramedics, and other personnel working at the scene of an incident from potential hazards posed by passing vehicles.

In a dynamic environment like a traffic incident scene, maintaining a safe distance from traffic is essential to reduce the risk of accidents, ensuring that first responders can effectively perform their tasks without the immediate threat of being struck by vehicles. This practice is part of a broader approach to incident management, where safety for both responders and motorists is a top priority.

While increasing traffic flow efficiency, accommodating more emergency vehicles, and keeping the roadway free for civilian use are important considerations in overall traffic management and operational effectiveness, the primary focus of taking additional lane space in block positioning is to ensure the safety of personnel actively engaged in the emergency response.
