Los Angeles County Sheriff's Department (LASD) RADIO Practice Exam

When an officer uses code 911B, they are referring to the need for a contact officer. This code indicates that the officer is requesting a partner or additional officer to be present for communication, support, or safety purposes, especially in potentially dangerous or complex situations. This protocol ensures that officers can maintain a high level of situational awareness and enhance their safety interactions with the public or when handling incidents involving suspects. While the other codes might also be relevant in various situations, they each denote different situations or requests entirely, making them less suitable in this context where a direct call for a contact officer is needed.
