While saving commercial fleets and drivers time and money, many of us here at Bestpass have learned a thing or two about slang on the road. Here are some of our favorites and what they mean:

Bobtailing- Traveling from one point to another without a trailer in tow.

Jackknifing- a common trucking accident term that refers to the dangerous situation when a semi-tractor trailer or 18-wheeler skids, causing the trailer to swing out to one side forming an angle that resembles the angle that the blade of a jackknife forms with its protective handle.

Yard jockey- A terminal tractor, known in the United States as a spotter truck, spotting tractor, yard truck, yard dog, yard goat, yard jockey or mule, is a semi-tractor intended to move semi-trailers within a cargo yard, warehouse facility, or intermodal facility, much like a switcher locomotive is used to position railcars.

Less-than-truckload (LTL)- the transportation of relatively small freight.

Intermodal- transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation (e.g., rail, ship, and truck), without any handling of the freight itself when changing modes.

Final mile- is a term used in supply chain management and transportation planning to describe the movement of people and goods from a transportation hub to a final destination in the home.

Alligator- A tire recap or tire part from a blown tire on the road.

Wiggle wagon- A truck pulling two or three trailers.

Chicken coop- a weigh station.

Dead head- to haul an empty truck. Usually driving empty means you are not getting paid for the trip and you have to drive somewhere to get a load.
