What is the term used when an officer informs their location to their station?

The correct answer identifies the specific action of an officer notifying their station about their current location by stating they are "returning to station." This term is regularly used in law enforcement communication to clearly convey that the officer is on their way back to their home base for various reasons, such as completing reports, taking breaks, or ending their shift. Clear communication of location is essential in policing for situational awareness and resource management.

In contrast, the other terms do not necessarily indicate an officer's location specifically. "Cancel last message" would be used to retract an earlier communication, "request a warrant check" refers to asking for information regarding a warrant on a subject, and "standby" typically implies that the officer is waiting for further instructions rather than communicating their location. Thus, "return to station" is the most precise term that accurately conveys the action of informing a station about an officer's location.
