A Shunt truck, known in the U.S. as a Spotting tractor, Terminal tractor, Yard truck, Yard Dog, Yard jockey, mule, etc. is a semi-tractor intended to move semi trailers within a cargo yard, warehouse facility, or intermodal facility, much like a switcher locomotive. It is rare for these vehicles to be on public roads. The Shunt truck of this design seems to be distinctly North American. There are only two manufacturers, who use generally the same specs, located in North America.

Distinctions between a Shunt truck and a regular Truck are several and noticeable:

  • A distinctive single person cab offset to the left of the engine.
  • A very short wheelbase, usually with a solidly mounted single rear axle.
  • A low power Diesel or alternate fuel engine with an automatic transmission.
  • A fifth wheel with an integrated lifting mechanism designed to allow the semi-trailers legs to remain in the down position during movement. 15 inches (380 mm) and 70,000 lb. of hydraulic lift are typical.
  • 12-gauge steel side wall Cab construction with 1⁄2-inch (13 mm) steel floors for protection in abusive & dangerous work environments.[1]
  • 360 Degree View to facilitate five to six moves an hour.
