What tools are commonly used to detour traffic around an emergency scene?

The correct answer involves lights and traffic cones, as these tools are widely recognized for managing traffic around emergency scenes. Traffic cones are essential for clearly marking the perimeter of an incident and directing vehicles away from hazardous areas. They are highly visible and can be quickly deployed to establish safe pathways for detoured traffic.

Lights, especially flashing or rotating emergency lights, enhance visibility during both day and night. They serve to alert motorists to the presence of an emergency situation, prompting them to slow down and take notice of the detours. When combined, these tools provide clear guidance and help maintain safety for both responders and the public in high-risk environments.

While other options do include traffic management tools, they may not be as directly suited for immediate, on-scene detouring as the combination of lights and cones.
