If you have responded to an emergency on a limited-access highway and your apparatus is not in use, you should:

• A. Position across the intersection to block traffic
• B. Use the apparatus as a barrier between the traffic flow and the responders on scene
• C. Position the apparatus off the highway in an area away from the incident
• D. Position the apparatus as close to the incident as possible so responders will have access to the apparatus

Answer: (B)

On a limited‑access highway, protecting responders from passing traffic is the priority. Using the apparatus as a barrier creates a physical shield between the traffic flow and personnel, establishing a safer work area behind the vehicle and helping to reduce the risk of secondary crashes. This placement provides immediate protection while crews work and can support incident containment and traffic control efforts. Putting the unit across an intersection isn’t appropriate on a highway segment and can create unnecessary blockages; parking it away from the scene removes that protective buffer, leaving responders exposed or forcing longer access for operations; placing the apparatus too close to the incident diminishes the shielding effect and can hinder movement and equipment access.
