Police Code 3 usually means an emergency response, often with lights and sirens. It is the kind of shorthand that tells everyone the unit is moving fast and the call needs immediate attention.
If you are comparing response codes, the best starting points are our Police Scanner Codes guide and the more general homepage hub for common code meanings.
What Code 3 Means
Code 3 usually means a high-priority emergency response. In many places, that means the unit may use lights and sirens to reach the scene.
Common Use in Police Radio and Scanner Traffic
Code 3 is heard when an incident needs urgent response and the dispatcher wants the unit to move immediately. Scanner listeners often hear it attached to accidents, active disturbances, or other calls that need speed.
Plain-English Example
A dispatcher might say, “Respond Code 3 to the scene,” which tells the unit to treat the trip as urgent and follow emergency driving policy.
Important Variation Note
Code 3 is not handled exactly the same everywhere. Some agencies use it mainly for emergency driving, while others use it as a broader response level or avoid the code entirely.
For more response-code context, compare Police Scanner Codes, Code 4, and Police Code 11-99.
FAQ
Is Code 3 the same everywhere?
No. It is common, but departments can define response levels differently, especially in mixed-radio or regional systems.
Does Code 3 always mean lights and sirens?
Often, yes, but the exact driving policy belongs to the agency. Some departments give officers narrower or broader discretion.
Is Code 3 used by fire or EMS too?
Some public safety agencies use response codes similarly, but the wording and meaning can differ by service and region. Always read it in context.
What should I compare with Code 3?
Code 4 is the natural opposite in many systems, and 10-33 or 11-99 can also show up in urgent traffic. Those pages help explain the full response pattern.
