What is the purpose of using traffic control devices during an emergency response?

The primary purpose of using traffic control devices during an emergency response is to manage the flow of traffic for safety. This is essential to ensure that emergency vehicles can navigate through traffic efficiently and reach the scene of an incident as quickly as possible while minimizing the risk of accidents. Proper management of traffic helps to create a safe environment for first responders and prevents chaos that could arise from unregulated traffic. By providing clear signals and guiding the behavior of other drivers, traffic control devices help maintain order and protect both the emergency personnel and the public.
