purchase [ The Best of CW McCall ]
I would not have thought so, but apparently trucker CB radio is still a thing - even in this day of digital phones that do the same and more than Citizens Band radio. One source of internet information claims that CB use is fading. Another says that 90% of professional drivers call it a critical tool with about 6 million CB radios still in use in the US.
CB culture of the 1970s developed its own language, including the classic <Break> or sometimes <Breaker>: the code to interrupt all other comms on a channel and insert one's own message atop all others. A number of songs and movies dealt with the American fascination with trucker issues, many related to protests over the 55 MPH speed limit imposed to deal with rising oil prices during the 1973 energy crisis.

McCall wrote a new version with "saltier" lyrics specifically for the film. Other musicians in the film's soundtrack include a veritable who's who of country: Glen Campbell, Merle Haggard, Kenny Rogers and Doc Watson. There's also various other - some politically incorrect - versions of the song
