Which code indicates a situation requiring response with lights and sirens?

The code indicating a situation requiring response with lights and sirens is Code 3. This code signifies an emergency situation where there is a need for immediate response, allowing officers to use both lights and sirens in order to alert other road users and expedite their response to the scene. The use of lights and sirens is crucial for responding to incidents where time is a critical factor, such as in cases of life-threatening emergencies or serious crimes in progress.

Other codes, while important, do not indicate the same level of urgency. For example, Code 2 generally signifies a non-emergency response that may require prompt attention but does not necessitate the use of lights and sirens. Understanding these codes helps in appropriately managing responses and ensuring that officers react correctly based on the severity of the situation at hand.
