Created out of the words "keep on truckin" One of the most popular slang expressions, 'Keep On Truckin' originally came from a one-page magazine comic. It is more commonly associated with truckers and rock n roll because of classic rock songs that used the the word “truckin’” in them. The simple message is to keep on doing what you do, no matter the obstacle. We took the image of a big rig truck and created it out of the saying.
