Farm equipment dealers may allow farm equipment haulers to act as their representative when hauling farm equipment to or from the dealer's place of business. Farm equipment haulers shall carry in the motor vehicle hauling the farm equipment a signed statement from the farm equipment dealer stating that they are acting as a representative of the farm equipment dealer. The statement shall be dated and valid for ninety days and shall be subject to inspection by any peace officer. The statement shall indicate the name of the farm equipment dealer, the name of the hauler, and that the dealer authorizes the hauler to act as its representative for purposes of complying with width, height, and length limitations. Nothing in this section shall require farm equipment dealers to provide insurance coverage for farm equipment haulers.
