What can proper traffic control devices help reduce at an incident?

Proper traffic control devices are essential at an incident scene as they help manage the flow of traffic, ensuring that vehicles navigate safely around the incident area. This control is crucial in reducing public interference. When traffic control devices such as cones, flares, and signage are used effectively, they direct drivers away from hazards and the area where emergency responders are working, minimizing the potential for further accidents or injuries.

The reduction of public interference is significant for the safety of both the responders and the public. By clearly marking the incident scene and guiding traffic appropriately, these devices enhance situational control, allowing emergency personnel to perform their duties without unnecessary distractions or disruptions caused by onlookers or errant vehicles. Therefore, the correct answer emphasizes the importance of traffic control devices in maintaining safety and order during emergency incidents.
