What term describes when there is limited or no buffer space between on-scene vehicles and any active lane of traffic?

• A. Buffer Zone
• B. Zero Buffer
• C. Traffic Buffer
• D. Full Buffer

Answer: (B)

In crash scene safety, the space between on-scene vehicles and nearby moving traffic is a key risk indicator. When that space is minimal or nonexistent, it’s described as zero buffer. This term specifically communicates that there is no protective gap to shield responders from passing vehicles, which heightens danger and often requires heightened safety measures at the scene.

This is the best choice because it directly labels the absence of buffer space. The other terms imply there is some buffer or aren’t standard terminology for this situation, so they don’t describe the risk as accurately.
