Which description matches code 444?

• A. Panic alarm at metro facilities
• B. Explosive device
• C. Keep the peace
• D. Officer needs help emergency

Answer: (D)

This item tests recognizing an urgent on-scene signal indicating an officer in danger. Code 444 is the clear banner for an officer who needs immediate assistance, signaling that back-up and possibly medical support are required right away. That immediacy is what sets it apart from the other descriptions: a panic alarm at metro facilities points to a location-specific alert, not necessarily an officer in distress; an explosive device describes a threat or device requiring a specialized response; keep the peace refers to routine or ongoing duties with no immediate danger to a specific officer. So the description that matches is the one signaling an officer needs help emergency, because it directly communicates the urgent need for immediate assistance to the responder.
