Which code would an officer use to indicate they are busy?

The code indicating that an officer is busy is indeed 10-6. In police communication, the ten-codes, often referred to as ten signals or ten signals, offer succinct ways for officers to convey information over the radio. Specifically, 10-6 is used to signify that an officer is occupied with a task or activity that prevents them from responding to additional calls or communications, thus it is essential for coordinating resources effectively in a busy environment.

The other codes carry different meanings: 10-5 typically relates to a request for information or additional help, 10-4 is a response indicating acknowledgment or understanding of a previous message, and 10-3 is used to advise to stop transmitting. Each code has its own specific purpose, and understanding these distinctions is crucial for clear and concise communication in law enforcement operations.
