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

Which command should a unit follow if they receive CODE 4N?

1. No assistance needed. No evidence of crime

2. Clear your MDT buffer

3. Monitor your MDT

4. Emergency. Use red lights and siren

The correct answer is: No assistance needed. No evidence of crime

The command associated with CODE 4N indicates that the unit has assessed the situation and determined that no assistance is needed, and there is no evidence of a crime. This code is used to signal to other units that the situation has been resolved or that it does not require further law enforcement intervention. This means that officers can proceed confidently with their duties, knowing that the current scene is under control. Therefore, the information conveyed by CODE 4N helps prevent unnecessary deployments of additional resources and allows for more efficient allocation of law enforcement assets. The alternatives presented do not align with the definition of CODE 4N. For example, clearing the MDT buffer would not be applicable in a situation that has already been assessed as resolved. Monitoring the MDT or responding to an emergency with lights and sirens does not fit the context of having no immediate concerns or requirements for further assistance, which is at the heart of CODE 4N's message.
