In law enforcement communication, which code indicates the presence of authorities on the scene?

The code that indicates the presence of authorities on the scene is 10-98. This code serves to inform officers and dispatch that they have arrived at a location where law enforcement activities are taking place, promoting situational awareness among personnel involved in the incident.

Utilizing this code enhances coordination and communication, ensuring that all units are aware of who is on scene and can accordingly update their actions or response plans. This clarity is crucial in fast-moving scenarios where multiple officers may be responding to a single incident, helping to prevent confusion and ensure that all parties are informed about the current status of the situation.

Codes like 10-96, 10-71, and 10-70 refer to other specific situations that do not indicate presence. For example, 10-96 refers to mental subject, 10-71 deals with firearm discharge, and 10-70 pertains to a fire alarm. Each of these codes serves distinct purposes in communication but does not convey the same meaning as 10-98 regarding officials at the scene.
