What is indicated by the code 10-21?

The code 10-21 indicates "Call Station." This code is used in law enforcement to instruct or indicate that an officer should contact the station or dispatch. It's a common practice for officers to communicate with their central command, particularly for non-emergency updates, requests for information, or coordination of activities. Understanding this code is essential for maintaining effective communication in the field.

The other choices refer to different scenarios that have their own designated codes. "Road/Weather Conditions" deals with information about environmental factors affecting law enforcement operations, "Subject in Custody" specifies the status of an individual taken into custody, and "Miscommunication" pertains to potential misunderstandings in communication. Each of these situations would require distinct codes to convey important information succinctly on the radio, which is why they are not the correct interpretation of 10-21.
