What does 10-23 indicate?

What does 10-23 indicate?

• A. Standby
• B. Call by telephone
• C. Disregard
• D. Send backup

Answer: (A)

This question tests knowledge of public-safety radio codes, where officers use compact numbers to communicate status quickly. The ten-series codes are a universal shorthand for common actions. Specifically, 10-23 means Standby, signaling that you should pause and be ready for further instructions rather than actively engaging. Use this when you’ve arrived or are in a position to act but need to wait—for example, when you’re waiting to assess a situation, awaiting backup, or waiting for the air to clear before proceeding. Acknowledge the call and hold your position, keeping the channel clear for urgent traffic until you’re directed to proceed.
