Though there are many trucker codes that have become nationally (even internationally) recognized, there are many trucker codes / terms that are more regional. Terms also change over time, such as “good buddy” once referred to a friend, but it evolved into a slang word with a totally different meaning this nova days.
Something else that is very common with the use of a CB is not using your real name. Operators have developed a variety of nicknames, handles, to identify themselves. It might not be a common as it once was, but we all remember the movie ‘Convoy’.

The use of trucker codes was actually started in the USA and over time it has worked its way to truckers around the globe. The first to pick up the use of trucker codes was Canada, second one that start using the trucker codes was Mexico, and even Germany start with use of the trucker codes, before really gaining traction. Now each region has developed their distinctive trucker codes. Sometimes the transition was smooth other times not so much. In French-speaking Canada the cultural mood of the area caused some conflict with adopting the trucker codes.
