Which code indicates an emergency?

• A. Code 20
• B. Code 30
• C. Code 1000
• D. 10-21

Answer: (C)

Recognizing an emergency signal in radio codes means understanding that some numbers are reserved to flag immediate danger and require a rapid, prioritized response. When a message carries that emergency designation, dispatch and nearby units drop into high-alert mode, ready to move quickly to the scene, while maintaining safety and communication discipline. In this set, the code designated for an emergency is the one that signals urgent, life-threating circumstances and triggers that immediate response. The other signals represent routine status, non-emergency conditions, or standard contact instructions, so they do not prompt an urgent deployment. Remember, different agencies may use different numbers for their codes, but in this context, the emergency code is the one described.
