Insurance requirements for motor carriers

​Intrastate and interstate for-hire motor carriers of property and passengers, any carrier of passengers by motor bus, and persons engaged in leasing motor vehicles without drivers must file evidence of proper insurance coverage as set forth in Sec. 194.41, 344.51, and 344.52, Stats. and Wis.
