Which of the following indicates that an officer is currently operational?

The designation "10-8" signifies that an officer is operational and available for assignments. In police communication, codes are used for efficient and clear interactions, particularly over radio channels where brevity is crucial. When an officer states they are "10-8," it communicates to dispatch and other officers that they are actively on duty and ready to respond to calls for service.

Understanding this code is important for maintaining coordination among law enforcement personnel. Being "10-7," on the other hand, indicates an officer is out of service, which contrasts with the operational status represented by "10-8." The code "10-0" typically refers to a warning or alert about potential trouble, not directly relevant to an officer's current operational status. "10-3" is often a request to stop transmitting, again not indicating an officer's operational readiness. Overall, "10-8" is the clear choice in this context, representing an officer's active engagement in their duties.
