10-30: Unnecessary Use of Lights/Siren

In APCO 10-codes, 10-30 refers to "Unnecessary Use of Lights/Siren."

This code is utilized by law enforcement to indicate that an officer or other personnel is observing or responding to a situation where the use of lights or sirens is not warranted. The purpose of this code is to promote professional conduct and ensure that emergency signals are used appropriately, especially in non-emergency situations.

For example:

  • Officer: "Dispatch, I’m observing a vehicle with its lights flashing but not responding to an emergency."
  • Dispatcher: "Copy that, you are reporting a 10-30."

Using 10-30 helps maintain public trust and safety by ensuring that emergency equipment is not misused, which can cause confusion or panic among the public. It reinforces the importance of using lights and sirens judiciously to reserve them for actual emergencies.
