Michigan Oversize and Overweight Trucking Permits Requirements
Michigan legal size and weight limits are clear: standard vehicles may not exceed 53 feet in length on interstate and designated highways, 8 feet 6 inches in width on these routes, 13 feet 6 inches in height, and 80,000 pounds gross weight with specific axle limits. Loads surpassing any of these require appropriate Michigan oversize and overweight permits, which must be obtained prior to entering the state. A Permits ensures your applications meet every aspect of these requirements, avoiding costly violations and delays.

Michigan Oversize Load Regulations and Travel Windows
Operating times for oversize vehicles are generally from sunrise to sunset. Michigan allows weekend travel on a trial basis for certain loads not exceeding 10 feet wide, 14 feet high, and 90 feet long, limited to daylight hours until 3:00 pm. Loads exceeding 12 feet in width or 90 feet in length face restricted travel during peak hours (7–9 am, 3–6 pm) on major corridors in counties such as Wayne, Oakland, and Kent, with no travel permitted on major holidays or holiday weekends.

Cost Transparency and Escort Requirements in Michigan
The Michigan oversize permit and overweight trucking permits cost varies based on load dimensions, weight, route, and permit duration. Escort requirements also depend on load size one escort is compulsory for widths over 12 feet and lengths beyond 90 feet, with two escorts mandated for loads exceeding 14 feet in width or 100 feet in length. Additionally, escort needs extend to overhang and height parameters, reflecting Michigan commitment to road safety.
Special Considerations for Bridge Crossings and Seasonal Restrictions in Michigan
For bridge crossings, regulatory compliance includes advanced notification to the Mackinaw Bridge
Authority and fees and restricted hours for Ambassador Bridge crossings in Detroit. Seasonal construction and spring thaw restrictions (normally February to April) impose reduced axle weight limits and routing limitations, with no overweight permits issued during this period. A Permits stays informed on such restrictions to provide proactive guidance.
Commitment to Safety and Compliance in Michigan
Michigan law mandates all oversize loads display “Oversize Load” signs, with flags and lights positioned at load extremities, ensuring visibility during transport. Lift axles must be grounded under load, and escort vehicles provide additional oversight on complex routes. These regulations preserve infrastructure and public safety.
