What does Signal 6 advise regarding previous traffic?

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

Answer: (C)

Signal 6 indicates "Reference previous traffic," meaning it's used to instruct officers to look at or consider previous communications or traffic stops related to a particular situation. This signal plays a crucial role in ensuring that officers can review past interactions or pertinent details that could influence their current actions or decisions, hence promoting safety and informed responses.

In traffic enforcement or criminal investigations, being aware of prior traffic incidents can provide valuable context, such as the behavior of a suspect, the conditions of a situation, or relevant warnings. This approach helps maintain continuity in law enforcement interactions and aids officers in making well-informed choices during their operations.

The other options do not align with the specific directive of Signal 6, as they pertain to operational status and ability to receive signals rather than referencing previous communications.
