In law enforcement terminology, what does the term "Code 3" signify?

The term "Code 3" signifies a response to an emergency situation where law enforcement officers are required to use both lights and sirens while responding. This indicates a need for urgency in reaching the scene of an incident—such as a serious accident, violent crime in progress, or other scenarios that pose an immediate threat to public safety. By using lights and sirens, officers can alert other drivers and pedestrians, ensuring a quicker and safer path to the emergency location while also signaling the gravity of the situation they are responding to. This understanding is critical for maintaining effective and responsive emergency services in law enforcement.
