911 Dispatcher Practice Test

What does the code 10-3 signify?

1. Stop transmitting

2. Signal good

3. Acknowledgement

4. Relay

The correct answer is: Stop transmitting

The code 10-3 signifies "Stop transmitting." This code is part of the ten-codes used in law enforcement and emergency communication to convey clear and concise information over radio channels. When a dispatcher or an officer uses the code 10-3, it serves as an instruction for the receiving party to cease their current transmission. This might be necessary in scenarios where interference could disrupt critical communications, such as during ongoing operations or when multiple parties are trying to communicate simultaneously. By using standardized codes like 10-3, dispatchers can maintain clarity and efficiency in their communications, ensuring that important messages are not lost or misinterpreted.
