What type of traffic control devices helps reduce the chance of secondary crashes during traffic incidents?

Traffic management strategies are designed to effectively coordinate and direct traffic around incidents, minimizing congestion and the likelihood of secondary crashes. Secondary crashes often occur when drivers do not slow down or change their behavior in response to existing hazards on the road. By implementing traffic management strategies, such as real-time information dissemination, detours, and lane closures, responders are able to manage the flow of traffic around an incident scene more efficiently. This proactive approach informs drivers of the situation ahead, allowing them to make safer choices and reducing the chances of additional accidents.

In contrast, warning signals and traffic cones serve as immediate visual cues but do not provide the broader, strategic planning needed to manage traffic flows effectively. Flashing lights can alert drivers to an incident, yet without coordinated management of surrounding traffic, they may not significantly reduce the risk of secondary incidents. Therefore, traffic management strategies are crucial for creating a comprehensive safety environment during traffic incidents.
