The following is a list of CB radio "10 codes". Ten codes are an abbreviated way of sending messages, some of which are very common among those that use CB radios frequently or professionally. If you're new to the CB world, take a look at the list below to get familiar with some codes you may hear.
As you can imagine, some are more popular than others. I don't recommend that you memorize the list below, just use it as a reference if you hear something that you're not sure about. The list of 10 codes below was taken from the manual of a Cobra CB Radio.

Your blog is very informative, I have learned so much from it. It is like daily newspaper :). Added to favs.
Great to see a concise 10 code list. Thanks.
Thank you very much. This really helped me with my work. I appreciate your help. Thanks a lot.
What happened to the 10 - 100 Code? When I owned a Sideband CB radio years ago the 10 - 100 code was "Nature Calls". Just wondering why it's not included in your list of codes. I'm checking out the codes now because I drive school bus and they're using some of these codes on the radio.
Hi! I just wish to give you a huge thumbs up for your great
info you have right here on this post. I am coming back to your web site for
more soon.
Pretty! This has been an incredibly wonderful article.
Many thanks for providing this information.

If you want to get anywhere on CB, you have to be prepared to talk trucker talk, and that can mean learning a lot of rules of conduct. Learning CB lingo and radio code is a critical first step to effective communication.
what happened to the 10 - 0, means radio check
