This training promotes voluntary compliance to reduce damage to public roads and highways from overweight vehicles. Its goal is to teach you how to haul the most legal weight without violating truck-weight laws.

You'll learn about road-weight regulations during various times of the year, including the winter load increase and spring load restrictions. How trucks are configured—with proper axle spacing and tire size—makes a difference.

Instructors will provide professional, easy-to-understand take-home materials to assist you with your own configurations and options. The training is updated to reflect changes in truck-weight legislation.

This training will adhere to the public health requirements of the local jurisdiction and/or venue that are in effect at the time of each session. Details about these requirements will be communicated to registered attendees by email a few days before the training. Your health, safety, and well-being—and that of the community—are of the utmost importance to Minnesota LTAP and MnDOT. Thank you for your partnership in this public safety and public health effort.

Who Should Attend

Trucking entities who want to load to the maximum legal weight possible. Scale operators, farm truck owners and operators, aggregate haulers, truck manufacturers who configure truck axles and tires, township and county authorities who influence truck route weights, any company representative who influences the purchase or alteration of new trucks, out-of-state companies who need to understand and comply with Minnesota's legal weight limits, and truck driving students.

Please Note: This is not a “permitting” class for those who haul over-dimensional or overweight equipment that requires an oversize permit from either the state or county agencies. The class does cover the permit requirement for harvest and timber commodities and the 10 percent winter-load-increase (WLI) permit for trucks operating on Interstate highways.

Topics Covered

  • Update of road weight limits and differences between the state and local systems
  • Laws governing gross weights, axle weights, tire weights, road-restriction weights, and seasonally increased (winter and harvest) weights
  • Road damage issues: how overweight trucks cost us all
  • Overweight truck issues go beyond gross and axle weights
  • Classroom exercises to help you identify concerns in your own trucks
  • What’s different in axle spacing? Do I have the right tires for the weight?
  • Issues to consider when purchasing a new truck or altering a current truck
  • Introduction and demonstration of the new Minnesota truck-weight calculator, an online resource to help training attendees determine weights based on vehicle configuration
