What does Signal 3 signify about an officer's status?

• A. In service
• B. Out of service, subject to call
• C. Unable to copy, change location
• D. Reference previous traffic

Answer: (B)

Signal 3 indicates that an officer is "out of service, subject to call." This status is typically used in communication protocols to inform dispatch and other officers that while the officer is not actively on patrol or responding to calls, they remain available should the situation require their assistance. This status could arise if an officer is taking a break, engaging in non-enforcement activities, or handling administrative tasks.

This distinction helps maintain an efficient flow of information within the law enforcement community, allowing dispatchers to know which officers are readily available for new assignments or emergencies. Understanding this signal is crucial for effective coordination among officers and their communication with the dispatch center.
