Frost/thaw laws usually go into effect by February. However, commencing at 6:00 am on Monday, March 27th, 2023, the weight restrictions on all state trunkline highways in Michigan, from the southern border to US-10 in Ludington and extending northwards to US-23 in Standish, will be lifted. These highways, typically designated as M, I, or US routes, are subject to temporary postings designed to safeguard vulnerable roads under the frost laws. To obtain information on weight restrictions, dial 1-800-787-8960. For companies in Canada or New Jersey, contact 517-335-0023.
Maine Overweight and Oversize Winter Restrictions
Legal axle weight remains unaffected on “All Season Routes” (green or gold on the MDOT Truck Operators Map). Meanwhile, on “Seasonal” routes (solid or dashed red on the MDOT Truck Operators Map), there will be a 25% reduction for rigid pavements and 35% for flexible pavements. Extended permits are applicable for oversized loads only within the restricted area. Single-trip permits won’t be granted for overweight loads or those exceeding 14 feet in width, 11 axles, and 150 feet in overall length within the weight-restricted region. Michigan’s oversize and overweight regulations define the parameters for such loads. An oversized load is determined by dimensions, including a width of 8′ 6″, a height of 13′ 6″, and a length of 65′ for a truck-semi-trailer. Overweight loads, governed by maximum axle weights, set single axle limits at 20,000 lb., tandem axles at 34,000 lb., and a maximum gross weight of 80,000 lb.

Trip permits are essential for Michigan operators traveling out of state, and a 72-hour reciprocity permit is required for out-of-state operators entering Michigan. A Temporary Fuel permit is issued instead of IFTA licensing for travel within the state. Running hours are confined to daylight hours during weekdays, with holiday restrictions. Movement is allowed during weekends for specific load dimensions. Flags, banners, and warning lights are obligatory for oversized loads. Tire regulations in Michigan stipulate conditions under which pneumatic tires with embedded wire are permitted. Tread depth requirements and seasonal allowances for studded tires are specified.
Individuals and carriers are encouraged to contact the Michigan Department of Transportation directly at (517) 335-0023 to obtain accurate and up-to-date information on oversize and overweight load regulations and permits. This proactive approach to communication fosters a culture of safety and compliance within Michigan’s transportation industry.
