Which code should officers use to describe a scene that has been assessed or reached?

The code used to describe a scene that has been assessed or reached is indeed 10-23. This code signifies that an officer has arrived at a particular location and has assessed the situation at hand. It is essential for maintaining clear communication among officers, as it communicates to dispatch and other officers that the situation is under observation and that the officer is actively engaged with the scene.

The other codes have different meanings: 10-11 typically refers to a traffic stop, 10-15 indicates the arrest of a person, and 10-13 is used for requesting weather conditions. Each of these has a specific context and purpose within police communication, emphasizing the importance of using the correct code to convey precise information regarding an officer's status and the situation they are responding to.
