NLVPD Police Academy Codes Practice Exam - Practice Test & Study Guide

"10-3" generally refers to "Cancel the last message." This code is part of the ten-code language used in law enforcement and emergency communications, which helps convey information succinctly. When an officer or dispatcher needs to retract or cancel a previous communication, using "10-3" clearly communicates that intent without confusion.

Understanding this code is essential for effective communication within the police force and ensures that all personnel are on the same page, especially in high-pressure or rapidly changing situations.
