Which term describes blocking the involved lane plus one additional lane to provide a protective lateral space?

• A. Lane +1 Blocking
• B. Upstream Buffer Space
• C. Staging Area
• D. Incident Command Post

Answer: (A)

The concept tested is creating a protective space for responders by closing lanes to traffic. Lane +1 Blocking refers to closing the involved lane plus one adjacent lane to form a lateral shield around the work area. This provides a wider, safer buffer between workers and passing vehicles, making it easier to deploy equipment and move safely.

Upstream buffer space describes distance for slowing or diverting traffic before the scene, not the lateral protection right at the incident. A staging area is where resources gather, not a traffic-control measure. An Incident Command Post is the on-scene command location, not about creating a protective lane arrangement.
