A terminal tractor, known in the United States as a spotter truck, spotting tractor, yard truck, 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. Distinctions between a terminal tractor and a regular road truck are several and noticeable:
- A single person cab offset to the side of the engine.
