Which code indicates you are in service?

• A. 10-8 In service
• B. 10-9 Repeat
• C. 33 Clear radio for emergency traffic
• D. 10-20 What is your location?

Answer: (A)

Radio status codes tell dispatch and responders what you’re doing. Being in service means you’re on duty and available to take calls, and that status is indicated by the code for “In service”—10-8. This is the best choice because it directly communicates your availability to respond. The other options serve different purposes: 10-9 means you should repeat a transmission, 33 clears the radio for emergency traffic (a channel status instruction, not a personal availability status), and 10-20 asks for your location. So the code that shows you are in service is the one that says you’re in service.
