If you have line of sight to multiple units, what is the recommended radio approach?

• A. Broadcast to all units on every channel.
• B. Acknowledge each unit or use designated channel; avoid crowding the air.
• C. Ask one unit to relay to others.
• D. Silence the radio until only one unit is in range.

Answer: (B)

When you can see multiple units, the goal is to keep radio traffic clear and efficient so everyone stays informed. Acknowledging each unit or moving to a designated channel prevents crowding the airwaves with overlapping transmissions. This makes it easier for everyone to hear and understand, and it confirms that each unit has received important messages. Keeping a designated channel also concentrates traffic in one place, reducing interference and the chance that messages get lost.

Broadcasting to all units on every channel would create a jumbled, hard-to-follow stream and waste air time. Asking one unit to relay to others introduces delays and a single point of failure—if that relay misspeaks or misses something, others are out of the loop. Silencing the radio until only one unit is in range leaves others uninformed and can jeopardize coordination and safety.
