The timeless language of CB radio trucker slang

Learn how to talk like a true trucker with some of the most common CB radio slang.

The life of truckers remains somewhat mysterious to those unfamiliar with the daily routine of the profession. One of the most romanticized aspects of the industry is communication through CB radios. While truckers today have more communication options, many still turn to the reliable CB radio when they need to contact other drivers.

However, to use this device, which reached its peak in the 1970s, truckers must follow a specific communication etiquette. From the iconic “Breaker, breaker 1-9” to the formalization of everyday terms, communicating over CB radio is no easy task. Although some of these terms are well-known and popularized by TV and movies, a trucker must memorize them all to keep the conversation flowing smoothly.

10-4, the language of CB radios and truckers

CB radio slang has been an integral part of trucking culture since the ’70s, influenced by movies like Smokey and the Bandit and Convoy. While some terms are no longer as appropriate, others remain common in the transport culture.

Truckers need to familiarize themselves with the so-called “10-Codes.“ For example, the famous “10-4” means the message was received, or more complex ones like “10-13,” which is a request for weather or road conditions, and other necessary ones like “10-100,” meaning a brief stop for a bathroom break. So, whether you’re looking to join the trucking world or are simply curious, here’s a list of the most commonly used CB codes:

General CB Terms

10-4 – Message received
10-20 – Location
10-33 – Emergency
10-36 – Correct time

10-200 – Need police
Break (or Breaker-Breaker) – Request to join the channel
