In 1993, MN passed a law exempting Implements of Husbandry (IOH) from size, weight and load restrictions. Over the last two decades, as farming practices have changed from family to corporation, the size and weight of IOH have increased dramatically. As IOH’s continue to increase in size and weight, there is a serious concern on how they are damaging roads. The states surrounding Minnesota have addressed this concern by establishing maximum gross weights and gross axle weights; Minnesota has not. This brochure provides background information on the history of IOH’s; summarizes neighboring states IOH weight restrictions and provides links to recent research data that details the damaging effects IOHs have on pavements.
