Which 10-code indicates arrival on scene?

• A. 10-97
• B. 10-50
• C. 10-33
• D. 10-99

Answer: (A)

The main idea is knowing which radio code signals that you have reached the location. The code for arrival on scene is 10-97. When a unit says 10-97, it tells dispatch and other responders that you’ve arrived at the scene, are in position, and can begin the on-site assessment or action. This timing helps coordinate multiple units and prevent confusion as the response unfolds. The other codes point to different situations—10-50 is a traffic crash, 10-33 indicates emergency traffic or a request to clear the channel, and 10-99 is associated with a wanted person or a different condition—so they don’t convey being on scene.
