What should be done with vehicles that create a barrier at an emergency scene?

In the context of managing an emergency scene, it is essential to ensure that vehicles do not obstruct access or create additional hazards. When it is stated that vehicles “should remain unoccupied,” it emphasizes the importance of maintaining safety and operational efficiency at the scene. Unoccupied vehicles can serve as effective barriers to protect personnel and equipment from oncoming traffic or hazards, while allowing room for emergency responders to operate effectively.

Keeping vehicles unoccupied also mitigates risks, such as the potential for injuries in case the vehicle is hit or if it becomes involved in a secondary incident. It allows for a clearer and safer environment for both first responders and any bystanders, reducing the likelihood of chaos at the scene. Being unoccupied ensures that passengers or personnel are not put in danger and allows for quicker response and maneuverability when necessary.

Other options may involve risks or complications that could divert attention from managing the emergency effectively or could create further hazards, thereby underscoring the need to keep vehicles at the scene unoccupied.
