Signal 99 is associated with which of the following?

Signal 99 refers to a specific protocol within the Ohio law enforcement communication system, designated to indicate a Caution Ohio police initiative. This code is used to alert officers to be aware of particular situations or individuals that may pose a threat or require special attention.

The context of the other choices involves more specific incidents or criminal activities—homicide, burglary, and stolen vehicle reports—which do not align with the cautionary nature denoted by Signal 99. Therefore, the correct answer emphasizes the preventive aspect of the program rather than a response to a specific crime, highlighting the role of officers in ensuring safety and readiness for potential threats within their communities.
