What warning devices should a peace officer place at a crash scene?

The inclusion of signs, reflectors, flares, and cones at a crash scene is critical for ensuring safety and traffic management. These devices serve several essential purposes: they alert approaching drivers to the presence of an incident, help direct traffic around the scene, and ensure that the area is visible, especially in conditions with low visibility, such as nighttime or inclement weather.

Flares provide immediate visibility and can indicate the location of the incident from a distance, while reflective signs and cones enhance safety by marking off the area that should be avoided. This combination of devices creates a clear and effective means of communicating potential hazards to other motorists. In short, the utilization of all these warning devices is aimed at protecting both the individuals involved in the crash and other drivers on the road.
