What does code 10-1 mean?

• A. Unable to copy
• B. Acknowledgment (2 member team)
• C. Permit Check
• D. Disregard

Answer: (A)

Ten-codes are quick radio shorthand used by officers to keep traffic flowing. Code 10-1 is used when the speaker cannot copy the transmission clearly—due to weak signal, interference, or being out of range. In that situation, the officer would indicate they are unable to copy and typically ask the other party to repeat, or move to a better position or channel. That’s why the best answer is “Unable to copy.” The other phrases point to different, unrelated codes or actions (for example, an acknowledgment relates to confirming receipt, not an inability to hear).
