What does the radio code 10-23 signify?

• A. Call on the phone
• B. Disregard
• C. Arrived
• D. Report to

Answer: (C)

In police radio communications, officers use concise status codes to keep updates quick and clear. The code 10-23 means you have arrived at the location or on the scene. This signals to the dispatcher and other units that you’re on scene and ready to begin your assignment, which is why it’s the best choice. The other options don’t fit because they don’t represent a status of being on scene: calling on the phone isn’t a scene status; disregard isn’t a location/status update; and “report to” would indicate an instruction to go somewhere, not that you’ve already arrived.
