Citizens' Band Jargon

a wall of cb radios

Well, we laid a strip for the Jersey Shore
Prepared to cross the line
I could see the bridge was lined with bears
But I didn't have a doggone dime
I says "Pigpen, this here's the Rubber Duck"
"We just ain't a-gonna pay no toll"
So we crashed the gate doin' ninety-eight
I says "let them truckers roll, ten-four"

"Convoy," Words and Music by C.W. McCall, Bill Fries, and Chip Davis

"Convoy" was a hit song in the 1970s due in part to its use of trucker's CB jargon. People have always sought methods of communication that will plug them in to others with whom they feel they have something in common. Though previously primarily used by truckers, CB radio use grew into somewhat of a fad in the mid-70s. Consider it a pre-internet chat room.

Along with the rise of the CB's popularity, the unique language employed by its users blossomed into the American vocabulary (hence the popularity of "Convoy," a number one single in 1976). It was at this point that phrases like "Breaker, Breaker" and "10-4, good buddy" became a part of many people's very non-CB conversations.

Much of CB (and trucker) slang is based on the Citizens' Band 10-code, a sort of short hand developed to encode common transmissions in order and make communication more efficient (see chart below, gathered from The BigRadios.com website). If I asked you "what-s your ten-twenty?" you might respond "the homestead." If I heard you, I'd say "ten-four that." If signal interference made the transmission unintelligible, I may say "that's a ten-one, friend, can I get a ten-nine?"
