What does Signal 10 request an officer to do?

• A. Call by phone
• B. Rush
• C. In service
• D. Reference previous traffic

Answer: (A)

Signal 10 is a request for an officer to contact dispatch or another officer via telephone. This communication can be vital for coordinating efforts, sharing important information, or clarifying situations where immediate action is not required on the scene. Having a distinct signal for phone communication allows officers to streamline their interactions and maintain focus on their duties without unnecessary distractions. It's a critical signal for ensuring that officers stay informed and connected, which helps in managing law enforcement operations effectively.

The other options relate to different types of requests or commands; for example, "rush" would indicate urgency or immediate action, while "in service" typically means an officer is available for calls and "reference previous traffic" directs attention to prior reports or events. Each signal has its specific purpose, making it essential to understand the distinctions clearly.
