How is a work zone buffer area defined and used?

• A. A designated space for equipment storage near the shoulder.
• B. A designated space between traffic and workers to provide a safety margin and reduce risk of contact.
• C. A zone where pedestrians must be escorted by flaggers.
• D. An area used to move vehicles at a higher speed to avoid congestion.

Answer: (B)

A work zone buffer area is the designated space between moving traffic and the area where workers and equipment operate. It provides a safety margin that reduces the risk of contact between vehicles and workers, giving drivers a place to decelerate or recover if they drift toward the work zone. In practice, you see this area formed by cones, barriers, or other channelizing devices that clearly separate the travel lane from the work space. The buffer is not meant for equipment storage, not a zone where pedestrians are escorted by flaggers, and not a place to move vehicles at higher speeds to chase down congestion. Its purpose is to protect workers by maintaining a clear, recoverable distance from traffic and by giving drivers a safer path around the work zone.
