What is the purpose of a 900 code 'clear' or 'last' status?

• A. To indicate the incident is concluded or the unit is cleared from the assignment.
• B. To request additional units.
• C. To reassign the incident to another region.
• D. To mark a language barrier.

Answer: (D)

The status clear or last is about the end of the assignment. When a unit reports clear, it means the incident has been resolved and that unit is no longer needed at the scene and can return to service. If the unit is the last one on scene, last confirms all units have completed their duties and the scene is fully cleared. This helps dispatch and other units know the area is back to normal and resources can be released or reassigned.

The idea of marking a language barrier doesn’t fit this status. Language needs are handled through interpreters or translator requests, not by signaling that a scene is closed. So the purpose of clear or last is to indicate completion and the unit’s release from the assignment.
