What type of traffic should interrupt routine radio communications?

Priority traffic is the type of communication that should interrupt routine radio communications because it involves urgent information that requires immediate attention. This could include critical updates about safety, emergencies, or situations where timely communication is essential to ensure the safety of personnel or operations.

Normal update traffic, general inquiries, and non-urgent messages can typically wait until routine communication has concluded, as they do not pose an immediate risk or require prompt action. Therefore, it is essential to give priority traffic precedence to ensure that serious matters are communicated as quickly as possible, maintaining the safety and efficiency of operations.
