Wisconsin Statutes Vehicles (Ch. 340 to 351) § 349.22. Authority to establish mass transit way

(1) The department with respect to the state trunk highway system may by order, and any local authority with respect to highways under its jurisdiction may by ordinance, designate a portion of any highway under its jurisdiction as a mass transit way, designate the type and character of vehicles which may be operated thereon and specify those conditions under which any of said vehicles may be operated thereon. If car pool vehicles are permitted to use the mass transit way, the authority designating the mass transit way may specify the minimum number of occupants, including the operator, in the vehicles. In this section, the department's authority to designate a mass transit way is limited to freeway entrance ramps and state trunk highways connecting with or extending a mass transit way designated by a local authority.

(2) Whenever the department or local authority designates any highway or portion thereof under its jurisdiction as a mass transit way it may establish priority of right-of-way thereon and make such other regulation of the use of the mass transit way as it deems necessary. The department or local authority shall cause appropriate signs to be erected giving notice of priorities or regulations established under this subsection.

(3) The department or local authority designating the mass transit way may construct curbs, paint lines, erect signs or establish other physical separations to exclude the use of the mass transit way by vehicles other than those specifically permitted to operate thereon.
