Which code is used when an officer is asked to standby?

In law enforcement communication, codes are used to convey information succinctly and efficiently. The code used when an officer is asked to standby is 10-23. This code serves the purpose of notifying officers to pay attention and be ready to act or receive further information without taking any immediate action. The use of this code helps maintain clarity among officers while managing multiple situations simultaneously.

The other codes present refer to different police situations: for instance, 10-28 typically relates to vehicle registration checks, which does not apply in this context. The code 10-10 is related to negative communications, and 10-15 typically refers to prisoner transport. Thus, 10-23 is the most appropriate code for a standby situation, as it directly communicates the need for readiness without specifying immediate action.
