In MDPD practice, what does 10-4 indicate?

• A. Proceed with the dispatch.
• B. Acknowledgement or message received.
• C. Request to repeat.
• D. Stand by.

Answer: (B)

10-4 is the quick clearance code for “acknowledgement” or “message received.” When a dispatcher or another unit transmits an instruction or information, replying with this code shows you heard it and understand what was said, and that you will act or have acted as directed. It keeps conversations efficient and confirms the loop is closed. The other options describe different parts of radio dialogue: asking for a repeat is used when you didn’t hear something clearly, and stand by represents waiting or holding, not confirming receipt. Saying to proceed with the dispatch isn’t the confirmation itself—it’s an instruction or a cue to begin or continue the action, which is separate from simply acknowledging the message.
