CB Codes
CB 10 Codes (And What They ACTUALLY Mean)
Before smartphones, texting, and GPS apps, Citizens Band Radio (CB Radio) was the main tool for long-range communication on the road. Truckers used CB radios to stay connected during long hauls, share road conditions, warn each other about speed traps, and pass the time during long commutes.
Even today, CB radio communication remains a vital part of trucking culture. Over the decades, truckers have created a unique language known as CB radio lingo — a mix of slang, number codes, and shorthand phrases that make conversations faster and more entertaining. From famous phrases like “10-4” to colorful nicknames for police and traffic hazards, CB lingo is an important tradition that keeps drivers informed and connected.
In this guide, we break down the most common CB radio phrases, codes, and slang terms that every trucker — and curious listener — should know.
Here is a list of CB 10 codes, often followed by what they mean (and what they truly mean).
