Which section alerts drivers to the upcoming incident scene and the need to reduce speed or change lanes?

• A. Buffer Space
• B. Transition Area
• C. Advance Warning Area
• D. Incident Space

Answer: (C)

Advance Warning Area is where drivers first receive notice of the upcoming incident and are told to reduce speed or change lanes. This section is placed upstream of the incident so motorists have time to react, slow down, and begin lane adjustments before reaching the scene. It uses signs, warning boards, and other signals to communicate the upcoming change in conditions, helping to create a safer approach for both responders and drivers.

Buffer Space is the protected area behind the incident where responders operate and where vehicles should not encroach. Transition Area is where motorists actually begin slowing and moving from one lane to another as the work zone begins. Incident Space is the immediate vicinity of the incident where responders are working.
