What does Signal 15 instruct?

• A. Call home by phone
• B. Call radio by phone
• C. Call your post by phone
• D. Call GHQ by phone

Answer: (A)

Signal 15 is specifically used by the Ohio State Highway Patrol to instruct personnel to call their post by phone. This signal ensures that officers can communicate with their assigned post to report on their status, receive instructions, or relay important information.

In the context of a law enforcement environment, maintaining direct communication with the post is crucial for operational efficiency and safety. This allows for timely updates on any ongoing incidents or shifts in responsibilities. Other options, such as calling home or calling radio, do not align with the established protocols that Signal 15 is meant to provide. Therefore, the correct understanding of Signal 15 is that it pertains specifically to communicating with the officer's work station.
