Which type of communication is NOT part of the three types used on two-way radios?

Two-way radios are critical communication tools in emergency response settings, and they facilitate the exchange of essential information among team members. The three main types of communication on these radios include traffic, priority traffic, and emergency traffic.

Traffic communication is the standard operational communication that conveys necessary information without high urgency. Priority traffic is used for messages that require immediate attention but are not life-threatening, allowing for a structured approach to urgent matters without overwhelming the communication channel. Emergency traffic is reserved for situations where immediate and critical information must be conveyed, often involving life safety or urgent operational needs.

The term routine traffic does not align with the established categories for radio communication in emergency contexts. While it may imply standard communication, it lacks a defined purpose in the hierarchy of radio traffic classifications. Therefore, understanding that routine communication does not fit into the framework of critical communication types clarifies why it is not considered one of the standard types used on two-way radios.
