The History of CB Radio Culture in Trucking

The 1970s CB Boom

The story of CB radio in trucking starts with the FCC creating the Citizens Band radio service in 1958, giving ordinary Americans access to two-way radio without a ham radio license. But CB remained a niche hobby until the 1973 oil crisis changed everything.

When Arab oil producers imposed an embargo in October 1973, gas prices spiked and fuel became scarce. Truckers — who depend on diesel to earn a living — began using CB radios to share real-time information about which fuel stops had diesel and which were dry. Then in January 1974, the federal government imposed a national 55 mph speed limit to conserve fuel. Truckers, who were paid by the mile and lost significant income at 55 mph, began using CB to coordinate with each other about speed enforcement — where the “bears” were sitting and where it was safe to run faster.

By 1975, CB radio was no longer just a trucking tool — it was a national phenomenon. CB radio sales exploded from 1 million units in 1973 to over 12 million in 1976. The language of the road — 10-4, good buddy, breaker breaker, what's your 20 — entered mainstream American vocabulary.

Smokey and the Bandit and Pop Culture

Two cultural events cemented CB radio in the American imagination. In 1975, C.W. McCall released “Convoy,” a novelty song told entirely in CB slang about a trucker-led convoy from the West Coast to the East Coast, evading police the entire way. It hit number one on the Billboard Hot 100.

Then in 1977, Smokey and the Bandit starring Burt Reynolds became the second-highest-grossing film of the year. The movie was built entirely around CB radio, fast driving, and outsmarting “Smokey” (law enforcement). It turned trucker CB culture into a romantic, rebellious ideal that resonated far beyond the trucking industry. Millions of non-truckers bought CB radios for their cars just to be part of the culture.

Convoy Culture and the 55 mph Protests

CB radio gave truckers something they had never had before — the ability to organize in real time across hundreds of miles. And organize they did. In the winter of 1973-1974, truckers staged massive protests against fuel prices, speed limits, and weight regulations. CB radio was the coordination tool — drivers organized slowdowns, blockades, and convoy protests entirely over the airwaves.

The convoy became a symbol of trucker solidarity. A properly organized convoy had a “front door” (lead truck) and “back door” (rear truck), both responsible for bear reports. Trucks in the middle could run at the group pace, protected by the information network flowing through the CB. This format persists today — though true organized convoys are less common, the front-door/back-door system is still used whenever trucks travel together on the same corridor.

Decline and the Cell Phone Era

CB radio's mainstream popularity faded through the 1980s as the novelty wore off. For truckers, though, the CB remained essential until cell phones became affordable and reliable in the late 1990s and 2000s. Cell phones offered private, clear conversations without the noise, interference, and congestion of CB channels. The repeal of the 55 mph speed limit in 1995 also reduced one of the CB's primary use cases.

Channel quality also suffered. Without the FCC actively enforcing CB rules, channels became cluttered with profanity, skip interference (distant signals bouncing off the ionosphere), and intentional jamming. Professional drivers grew tired of the noise and some stopped using CB altogether, further reducing the number of useful conversations on the air.

The Modern CB Renaissance

Despite the decline, CB radio never fully died — and in recent years, it has seen a quiet resurgence among professional truckers. The reasons are practical: cell phones do not work in many rural areas where trucks regularly travel. CB provides instant, free, one-to-many communication that no app can replicate. When a wreck shuts down the highway or black ice appears on a bridge, the driver 2 miles ahead broadcasting on channel 19 provides information faster than any traffic app.

Newer drivers are rediscovering the value of CB radio after experiencing situations where it would have helped — construction zone navigation, parking updates at truck stops, and real-time weather reports from drivers ahead. The cultural legacy endures too: the slang, the etiquette, and the sense of community that CB radio created remain a core part of trucking identity.
