What is the primary role of a traffic control unit at an incident?

• A. Manage road closures, direct traffic, and ensure safe access for responders and evacuations
• B. Initiate medical triage at the scene
• C. Operate communications to dispatch
• D. Coordinate aerial surveillance

Answer: (A)

Traffic control at incidents centers on keeping roads open and safe around the scene to support responders and the public. The primary role is to manage road closures, direct traffic, and ensure safe access for responders and evacuations. By closing or detouring lanes, guiding vehicles away from the incident, and creating a clear path for fire, EMS, and other equipment, the traffic control unit prevents additional crashes and gives responders the space they need to work effectively. It also helps move people away from danger during evacuations and maintains orderly movement of traffic through surrounding areas. While medical triage belongs to EMS, and communications or dispatch functions are handled by dedicated units, and aerial surveillance is handled by aviation or specialized teams, none of these take precedence over establishing safe traffic flow and access as the incident evolves.
