Implements of Husbandry (IOH) Law

New Implements of Husbandry lighting and marking requirements effective November 1, 2015


Wisconsin has lighting and marking requirements for all Implements of Husbandry. As of November 1, 2015, self-propelled IoH and farm equipment exceeding 12 feet wide or that extend over the center of the roadway will have new lighting and marking requirements. This is to ensure the safety of IoH operators and the other traffic on the road. For more information on the new IOH regulations, visit Wisconsin Department of Transportation Agricultural Equipment and Vehicles Overview.
