MN DOT regulations for commercial motor vehicles
MnDOT Commercial Vehicle OperationsOfficial MN DOT websiteOverview
MnDOT Commercial Vehicle Operations and the Minnesota State Patrol handle motor carrier enforcement. Minnesota is a key northern freight corridor with I-94, I-90, and I-35 carrying significant truck traffic. The state's extreme winter weather and spring thaw create seasonal challenges for commercial vehicle operations.
Inspection & Enforcement Program
Minnesota operates weigh stations and mobile enforcement units. The State Patrol performs Level I through Level III inspections. The state has a strong enforcement presence on I-94, I-35, and I-90 corridors.
Weight Limits & Oversize/Overweight
Minnesota follows federal weight limits of 80,000 lbs GVW on Interstate highways. On state highways, Minnesota allows higher weights with specific axle configurations, up to 80,000 lbs on 5-axle combinations and higher for 6+ axle combinations with permits. The state has strict seasonal weight restrictions during spring thaw (March-May) that can reduce allowable weights by 40-50% on many roads.
Minnesota-Specific Requirements
- Minnesota has extensive spring weight restrictions (road restrictions) that significantly reduce allowable weights on state and county roads, typically from March through May.
- The state allows higher weights on non-Interstate highways with proper axle configurations and permits.
- Minnesota enforces specific winter driving requirements including tire chain provisions and speed reductions during winter weather.
- The state has a specific timber hauling permit system for the logging industry.
