Which police code corresponds with a situation requiring urgent response with lights and sirens?

In law enforcement, codes are used to communicate specific situations efficiently. The code that corresponds to a situation requiring an urgent response with lights and sirens is Code 3. This code indicates that officers should respond to an emergency with a heightened sense of urgency, which includes using both their siren and emergency lights to navigate through traffic and arrive quickly at the scene.

The necessity of this code arises from situations that pose an immediate threat to life, property, or may require immediate assistance, such as a serious traffic accident or an active crime in progress. The use of lights and sirens not only signals other road users to clear the way but also emphasizes the critical nature of the situation being responded to.
