59 CB Radio Codes You Should Know
If you’ve ever listened to a couple of veteran truckers having a conversation over CB radio‚ or police dispatchers barking out orders to coordinate a task‚ it might sound like a different language.
emergency radios: UV5R‚ Motorolas‚ ClipJam‚ and Tecsun
Part of this language consists of intricate numeric codes called 10-codes‚ so named because they all start with “10” followed by additional numbers.
It might sound completely impenetrable to outsiders‚ but that’s only because you don’t know the code.
It’s actually a lot easier to learn yourself with a little bit of practice and repetition‚ and a great way for you‚ your group and anyone else communicating on the CB band to save time and reduce ambiguity when the pressure is on.
I’ll be telling you the most useful and commonly used 10-codes in this article. Grab a notepad and let’s get going.
A Note on 10-Code Standardization… Or Lack Thereof
Before we dive right into the list of codes‚ I just want to make sure that you’re aware of the context in which you should use them.
If you’re just out rolling around I have a CB radio in your vehicle‚ don’t worry about a thing because most seasoned operators will know these codes and‚ in any case‚ if there’s serious trouble most people will probably communicate using plain‚ spoken language.
Likewise‚ if you’re talking with any other people in separate vehicles as part of a convoy‚ or members of your survival group‚ these codes will suffice just fine.
However‚ if you’re forced to communicate with law enforcement or emergency services via radio‚ you might want to think twice: 10 codes were first developed as long ago as the late 1930s‚ and have been in almost continual use ever since.
In time‚ according to regional‚ agency‚ and even individual departmental preferences‚ some of the codes came to take on different meanings‚ and were added to or incorporated into other code systems.
Accordingly‚ in the mid-2000s federal law enforcement agencies started advocating that 10 codes be dropped in favor of clear‚ concise language in high-pressure situations.
You’ll have no way of knowing if the agency you’re communicating with is using the exact same 10 codes that you are‚ and in a time is life situation that could end up costing you seconds or minutes that you just don’t have.
Just something to think about! Now‚ 10-28 and let’s get to those codes!
