What does Signal 2 indicate?

Signal 2 indicates that a unit is "In service." This means that the officer or unit is actively available for dispatch and operational duties. Being "in service" is crucial for coordination and efficiency in law enforcement, as it allows for effective communication among personnel and directed deployment of units to respond to incidents or assist the public. When units are designated as "in service," it notifies dispatch and other units that they are capable and ready to take on assignments.

This context is essential for understanding radio communications and operational readiness within law enforcement, helping maintain a structured response to emergencies and ensuring that officers are prepared to assist when requested.
