A yard truck is simply a truck that moves trailers in and around commercial freight yards.

 

Yard trucks let the driver move trailers without having to exit the cab or crank the landing gear due to being equipped with a hydraulic lifting fifth wheel. Once the trailer has been moved to its new destination within the yard, the driver can lower the trailer back onto the ground and uncouple the fifth wheel.

 

The benefit of a yard truck is that it can typically move three units in the same amount of time

that a standard tractor would move one.
