Long before cell phones and social media, CB (Citizen Band) radio was the communication tool of choice among truckers. Rather than communicating in full sentences, truckers mainly relied on CB 10 codes which allowed them to pass vital messages quickly and save airtime. With CB radio talk, you could effectively say more in little time.
You could ask a fellow trucker to call for an ambulance, warn of danger, or just pass relevant updates via CB radio codes. And even though we now have modern technology, the CB radio still exists. Learning these codes can help you in a lot of ways. It will help you communicate better with your colleagues, bond with them, and help you avoid confusion whenever you hear others using them.
So, let’s travel back to the 1900s, when these codes first emerged, and get familiar with some of the most popular ones.
