Which set correctly lists the ABCs of a radio call?

• A. Speed, Precision, Tone
• B. Clarity, Speed, Safety
• C. Accuracy, Brevity, Clarity
• D. Brevity, Courtesy, Calm

Answer: (C)

The main idea is that effective radio calls hinge on three linked qualities: accuracy, brevity, and clarity. Accuracy means the information you relay—who you are, where you’re located, what’s happening, and what actions are needed—must be correct so responders act on the right data. Brevity keeps the message concise, removing unnecessary words so important details get through quickly and the channel isn’t crowded with filler. Clarity ensures your message is easy to understand: speak clearly, use standard terms, and present details in a logical order so others can grasp the situation without ambiguity.

This combination—accurate, concise, and clear—best fits the ABCs of a radio call. The other options mix in speed, tone, safety, courtesy, or calm, which are useful qualities in communication but don’t form the essential trio that focuses on correct information, concise delivery, and unmistakable understanding.
