From an Underbody tool box to a Bill Of Lading: Here are 33 trucking terms you need to know.

When starting a new job, it’s easy to get overwhelmed with the jargon used by people who have been around for years. The trucking business is no different. Underbody tool box, semi truck accessories, cargo manifest, deadhead, CPM…there are hundreds of terms that can be mind-boggling.

We came up with a trucking glossary that includes some of the most common words used in the business and since Trebor Manufacturing is in the truck accessories business, we’ve included them so you don’t look like a fool when your boss asks you to check the cross frame tool box or to put the chains in the semi underbody tool box.
