Which statement should you avoid when using the radio?

• A. Yell over the radio
• B. Communicate confidential information
• C. Keep radio chatter to a minimum
• D. Use plain English

Answer: (A)

Clear, controlled radio communication is essential for safety and efficiency because radios are shared channels and messages must be heard, understood, and acted on quickly. Yelling over the radio breaks that flow—raising your voice creates extra noise, can drown out important details, and often leads to mishearing or misinterpreting what’s being said. In high-pressure situations, a calm, concise voice helps teammates process the information accurately and respond faster.

That’s why this practice is the one to avoid: shouting on the air. Other good habits—keeping radio chatter to a minimum and using plain English—help ensure messages are clear and quickly actionable. When sensitive information must be shared, it should be handled through proper, authorized channels rather than broadcast openly on the radio.
