Limit liability of agricultural vehicles

This bill limits the liability of owners, lessees, and operators of agricultural vehicles used on highways, capping their financial responsibility at $750,000 per claim and $1.5 million per occurrence. It defines agricultural vehicles to include farm tractors, implements of husbandry, self-propelled farm equipment, tractor-towed combinations, and vehicles used for hauling hay or straw. The legislation also amends existing state definitions to clarify terms related to agricultural operations, commercial motor vehicles, and other motor vehicle classifications. Insurance companies are prohibited from claiming the liability limitation unless they voluntarily agree to provide additional coverage through a written endorsement.
