The frozen road law allows heavier loads for trucks carrying logs cut crosswise (not including woodchips), and salt and sand for winter maintenance while cold weather allows. The seasonal weight restriction program is one way to protect Wisconsin’s investments in roads.
The department maintains an interactive map for seasonal weight restrictions, which shows the frozen roads boundaries, Class II roads and posted roads.
More information on overweight permits can be found on the WisDOT oversize/overweight permits webpage. Haulers with specific questions can contact WisDOT’s Oversize/Overweight Permits Unit at (608) 266-7320.
