The Complete List of CB 10 Codes (Citizens Band Radio)

CB radios represent the original social media for truckers. The specialized language truckers developed and popularized during the golden age of CB radios in the 70s, 80s, and 90s is still alive and well today. A cornerstone of this industry’s unique language is the CB 10 codes, first developed in the 1940s and later standardized in 1955. These CB radio codes were established to allow brevity and ease of messaging – a critical communication advantage for an industry facing the 1973 oil crisis.

The 1973 oil crisis had an immediate and negative impact on the transportation space. The U.S faced fuel shortages, gas station closures, and reduced speed limits nationwide. Adapting to the situation, commercial truck drivers began using CB radios to communicate which gas stations were open, how to avoid speed traps, and where to avoid traffic jams and accidents. These tactics helped to keep the nation’s supply chain moving and trucking companies to survive. By the time the oil crisis ended in 1974, CB radios were standard equipment in commercial trucks across the country, and the trucker’s language was firmly rooted.

CB radios are no longer essential equipment, yet they can still become your only lifeline during dangerous weather conditions. Despite being replaced as the primary means of communication, the trucker’s language that CB radios popularized still survives. It is widely used by veteran drivers and enthusiastically picked up by new operators. Learning the CB radio vernacular and CB 10 Radio Codes is not only an important communication skill, but it also indoctrinates you into the lifestyle and culture of trucking.

For newcomers to the trucking industry and road warrior veterans needing to brush up on their language skills, here is the complete CB 10 Codes list.
