What is a Code 4 status?

• A. Incident canceled or no incident; units return to service.
• B. Urgent response without lights and sirens; non-emergency but time-critical.
• C. Response to a potential incident.
• D. Emergency response with lights and sirens; highest priority for arrival.

Answer: (A)

Code 4 signals that there is no incident or that the incident has been canceled, and units can return to service. It means the dispatcher has confirmed no active action is required and crews should clear the scene or stand down, making resources available for other calls. This is different from an urgent but non-emergency response (time-critical but no lights and sirens), a standby for a potential incident, or an immediate emergency response with lights and sirens. The idea behind Code 4 is that the situation is resolved or canceled, so units are released from duty for that event.
