Which code indicates ARRIVED at the scene?

• A. 10-21
• B. 10-23
• C. 10-24
• D. 10-25

Answer: (B)

In patrol radio language, numeric codes are used to convey status quickly. The code that means you have arrived at the scene is 10-23. This code is specifically associated with being on scene, so it’s the best fit for indicating that you’ve arrived and are present at the location. Other codes have different meanings: 10-21 usually relates to contacting the station by phone, 10-24 signals that the assignment is completed, and 10-25 often means to meet in person. Note that some agencies use plain language instead of 10-codes, but within traditional 10-code usage, 10-23 is the on-scene indicator.
