Whether you call them Yard Dogs, Yard Trucks, Spotter Trucks, Terminal Tractors, Hostlers, Shunt Trucks, or Yard Mules, 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 a Pedestrian Safety-Working Around Trucks course.  This training is geared toward helping to keep employees safe while working in proximity to large trucks and powered industrial trucks. Designed to familiarize each attendee with the basic vehicle types and their function, along with control measures to reduce risk.

Classes for individual drivers now forming.  All classes held at YMS’ Pearland, Texas location.  The last two class dates for 2020 are: Thursday, October 29 and Thursday, December 10. Class requires 2 person minimum to form.
