  • Seasonal Weight Restrictions

    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 reduces 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. Please see below for more detail on the Permitting requirements and exempt classes by clicking here.

    EXEMPTION INFORMATION

    257.722(5) The exception to the loading maximums and gross vehicle weight requirements of subsection (11) under subsection (7) for a person hauling agricultural commodities or a public utility vehicle applies only if the person who picks up or delivers the agricultural commodity either from a farm or to a farm or the public utility notifies the county road commission for roads under its authority not less than 48 hours before the pickup or delivery of the time and location of the pickup or delivery. The county road commission shall issue a permit to the person or the public utility and charge a fee that does not exceed the administrative costs incurred. The permit shall contain the following: (a) The designated route or routes of travel for the load. (b) The date and time period requested by the person who picks up or delivers the agricultural commodities or the public utility during which the load may be delivered or picked up. (c) A maximum speed limit of travel, if necessary. (d) Any other specific conditions agreed to between the parties.

If a request is denied, the written notice shall state the reason for denial and alternate routes for which the permit may be issued. The applicant shall have the right to appeal to the state transportation commission or the county road commission. These exemptions shall not apply on county roads in counties that have negotiated agreements with milk haulers or haulers of other commodities during periods of seasonal load limits before April 14, 1993. This subsection does not limit the ability of these counties to continue to negotiate such agreements.

    Michigan's county road agencies are working to improve roads to accommodate
    commercial vehicles, but increasing costs and declining
    revenues delay these costly improvements. To learn more about
