Seasonal weight restrictions were enacted in order to help minimize the impact of heavy trucks on Michigan's roads during the Spring cycle of freezing and thawing. By law, road agencies can enact weight restrictions on roads that are not designated as all-season routes when conditions merit.
Seasonal restrictions lower the axle-loading limits and reduce the maximum travel speed for certain vehicles. Details about seasonal weight restrictions and their effect on axle loading and speed can be found by clicking here for the full text of MCL 257.722. There are some limited classes that are exempt from these restriction after a permit is filed.
