What does 10-3 mean in OPP radio communications?

• A. Acknowledge; message received and understood.
• B. Repeat the last transmission.
• C. Location of the officer or incident.
• D. Stop transmitting; return to listening.

Answer: (D)

In OPP radio communications, numbers after 10 are quick actions you use to manage the airwaves. 10-3 specifically means stop transmitting and return to listening. It’s used when the channel is busy or you need to hear what others are saying or waiting for instructions from dispatch. By pausing your own transmission and staying tuned in, you help prevent channel congestion and ensure important messages aren’t garbled. This is different from other codes that might mean you’ve received a message, need a repeat, or need to share location, each serving its own purpose.
