Which message indicates the need to relay traffic information?

The correct response pertains to Signal 18, which is specifically designated for relaying traffic information. This signal serves as a standardized communication cue within the Ohio State Highway Patrol, ensuring that all officers are aware that relevant details regarding traffic conditions, incidents, or enforcement actions need to be broadcasted or communicated to other units or personnel.

In the context of law enforcement and highway patrol operations, clear communication about traffic conditions is critical for safety and efficiency. Signal 18 effectively alerts officers to the need to share important traffic updates, which can include things like accidents, road closures, hazards, or other information that may impact drivers on the road. Utilizing such standardized signals aids in maintaining effective situational awareness among all units in the field, enhancing their ability to respond appropriately to changing circumstances and ensuring public safety.

Other signals listed, while they may serve different purposes or indicate various statuses or actions, do not specifically pertain to traffic information relay. Each signal within this system has its unique purpose, allowing for a streamlined communication protocol among officers.
