How should the ambulance be positioned upon arrival to manage the scene?

• A. Park behind the vehicle, not blocking traffic.
• B. Position the ambulance to block traffic.
• C. Park as far away as possible.
• D. Park with engine idling near hazard.

Answer: (B)

Positioning the ambulance to block traffic creates a protective barrier between responders, victims, and oncoming vehicles, establishing a safe work zone. This setup channels and slows approaching traffic, reduces the risk of secondary crashes, and provides space for lighting, stabilization, and patient access from multiple sides. It also signals drivers to change course away from the scene, helping responders move and work more efficiently. Parking behind the vehicle or parking far away fails to shield the scene and delays access and protection, while idling the engine near a hazard unnecessarily increases exposure to fumes and noise. Blocking traffic is the practical, safety-focused choice for scene management.
