What is breaker 1 9?

"Breaker 1-9" is a phrase commonly used on radio communication to indicate that a message is about to be transmitted. The term evolved from the CB (citizens band) radio community, where people used the channel 19 for highway communication. "Breaker" refers to the act of interrupting conversations with a message.

The use of the phrase has now extended beyond the CB radio community and into other communication systems. It is still used in trucking and transportation industries to indicate the start of a message. However, it is less commonly used in other industries, such as aviation and marine, where different codes and phrases are used.

In addition to "breaker 1-9," other popular radio communication lingo includes "10-4," meaning "message received and understood," and "smokey," referring to a police officer. These codes and phrases are crucial for effective communication in emergency situations, where clear and concise messages can save time and lives.
