A trucker rolling down a highway and talking on a handheld receiver wired into a CB radio is one of the most enduring and iconic images associated with the American road. Movies like Convoy (1978) and Smokey and the Bandit (1977) helped popularize the association between trucking and CBs, but what really captured the wider public’s imagination was the colorful, strange lingo that truckers used when communicating over these devices.

CB (Citizens Band) radio lingo, often termed as “CB slang” or “CB talk”, is a shorthand form of communication that developed naturally over time among CB radio users, primarily truck drivers, and other mobile radio users. The inception of CB radio usage was around the 1940s in the United States, and it gained significant popularity during the 1970s, coinciding with a trucking boom and a surge in popularity of trucker culture, influenced partly by movies and songs, particularly in the country genre, of that era celebrating the trucker lifestyle.

The need for specific terminology or lingo arose out of practical and functional necessities. Truck drivers spent long hours on the road, and CB radio was a vital tool for communication, used to share essential information about road conditions, traffic, weather, and law enforcement activities. Given the CB radio’s open and public nature, having a coded language helped maintain a level of privacy and succinctness in communication.

The lingo allowed for quicker, more efficient communication. With short, standardized phrases, drivers could convey messages and information more swiftly, a critical aspect when relaying real-time road conditions or emergencies.

In addition, CB lingo helped forge a sense of community and shared identity among users, mainly truckers. It became an intrinsic part of the trucker culture, providing a unique language that bound the community together.

Another factor that influenced the development of CB Lingo was the need to discuss potential illicit activity, such as intentionally speeding, over the airwaves. Specific terms allowed drivers to talk about sensitive subjects such as police locations and speed traps without explicitly breaking any communication laws or guidelines. It added a layer of obscurity to the conversation, making it less likely to attract unwanted attention.

CB radios usually had a limited number of channels, making long conversations between multiple users difficult to manage. The coded language helped in managing conversations more efficiently, ensuring that critical information could be communicated promptly.

Just like regional terminology and slang will vary from state to state and city to city, as truck drivers traveled across states and regions, the terminology also evolved, adapting to various geographical, cultural, and situational contexts, making the language rich and dynamic.

Life on the road could be monotonous and lonely. CB lingo, full of imaginative and humorous phrases, added a layer of creativity and entertainment to otherwise mundane conversations, helping to lighten the mood and make the long hours more bearable.

The evolution of CB lingo was organic, influenced by various factors such as regional dialects, popular culture, and the changing landscape of the trucking industry. It served practical purposes but also became a cultural phenomenon, reflecting the life, challenges, and camaraderie of the road, especially within the trucking community.

The CB isn’t as popular today as it used to be. Where once CB radios were ubiquitous in long-haul trucks, today only about 32% of professional truck drivers say they communicate by CB regularly (although only 17% say they’ve never used a CB, so it appears that moderate use is still common). Although you may not hear as many ratchetjaw truck drivers (see below) on the CB today, a small number of amateur enthusiasts have always kept them in their personal vehicles, and that hasn’t changed much over time. Whether to pass the time or receive valuable insight into road conditions ahead—including weather, traffic, and the presence of speed traps—regular drivers enjoy using CBs too, but that requires learning the lingo to some degree.

CB Lingo, like any subset of slang terms (or, for that matter, any language) evolves over time with certain terms falling out of fashion and being replaced by new ones. In addition the usage, context, and implications of a particular term may change or vary based on the regional dialect. With all this in mind, compiling a glossary of CB terms is partly guesswork—the definition of a term here is based on popular usage, but real-world applications of them may vary. Here we’ve gathered some of the most popular and commonly used CB terms—ones we’ve seen and heard in movies and songs about the lives of truckers—and given what we think are the most broadly understood definitions of them. As ever always, your mileage may vary, but if you switch on a CB next time you’re headed down the open highway, here are some terms you might overhear.
