Which code corresponds to En Route?

• A. 10-4
• B. 10-20
• C. 10-23
• D. 10-17

Answer: (D)

En route means you’re in transit toward the call or location, not yet on scene. In radio codes, this state is conveyed with 10-17, so it’s the best choice for telling dispatch and other units you’re on the way. For context, 10-4 is an acknowledgment that you’ve received and understood a message, 10-20 reports your current location, and 10-23 indicates you’ve arrived on scene. Knowing these helps keep the response coordinated and everyone aware of your status as you move from en route to on scene.
