Whether you call them a Terminal Tractor, Yard Dog, Yard Truck, Spotter Truck, Hostler, or Shunt Truck, when these trucks are used off-road, they can be defined as powered industrial trucks by OSHA.  All operators of powered industrial trucks are required by OSHA to be authorized and trained. Operator training can not only reduce accidents, it can also increase productivity, operator safety, pedestrian safety, and may even help reduce insurance rates.

YMS operator training is designed to provide businesses and their yard mule operators with OSHA-compliant education on the safety, general usage, and general maintenance of a Yard Mule. Training includes training manual, group lecture presentation/discussion, written examination, and one-on-one driver training to demonstrate safe operation. We also offer expanded training, if more hands-on drive time is desired.

There is no minimum class size, we have done classes ranging in size from 2 - 22 participants. We conduct on-site classes nationwide, and can work with any schedule or shift.


This course is for the use and operation of non-highway yard mules only.  It is not intended as a substitute for D.O.T. or C.D.L. operator training.   Students must have a valid state motor vehicle license with at least one year of driving experience.

We also offer individual Operator Training at our Pearland location.  This is the same training as offered above, in a small class setting. Classes are limited to 2-4 participants. These classes are held the last Saturday of each month.  Registration is required by the Monday before class.
