Wis. Stat. § 218.0113

Subject to ch. 180 where applicable, any dealer, distributor, manufacturer or transporter of semitrailers or trailers designed for use in combination with a truck or truck tractor is considered licensed under ss. 218.0101 to 218.0163 where for purposes of chs. 341 and 342 a license under ss. 218.0101 to 218.0163 is required. This section is enacted to remove an undue burden on interstate commerce from a class of commercial transactions in which the business character of the parties does not require the protection provided by ss. 218.0101 to 218.0163 and to promote the expansion of credit for truck operators who require banking and financing facilities throughout the United States.
