What must be properly placed to shield responders from oncoming traffic?

1. Traffic cones

2. Emergency vehicles

3. Barriers

4. Warning signs

The correct answer is: Emergency vehicles

Emergency vehicles must be properly placed to shield responders from oncoming traffic. When responding to incidents, it is crucial to create an effective buffer zone between the roadway and emergency personnel. Positioning emergency vehicles at an angle and a sufficient distance from the incident site provides a physical barrier that helps protect responders from vehicles traveling on the road. This placement not only increases the visibility of the responders to oncoming drivers but also alerts the drivers to the potential hazards associated with the scene, allowing for better traffic management and ensuring the safety of both responders and bystanders. Properly positioning emergency vehicles also reinforces the urgency of the situation, prompting drivers to slow down or change lanes, further enhancing safety. In contrast, while traffic cones, barriers, and warning signs all contribute to safety at an incident scene, they do not provide the same level of physical protection as emergency vehicles. Traffic cones and warning signs serve to direct and alert traffic, while barriers offer a fixed obstruction. However, the dynamic nature of emergency vehicles allows them to adapt to changing situations and other traffic conditions more effectively. Thus, proper placement of emergency vehicles is critical for shielding responders effectively.
