Overview
MnDOT issues oversize/overweight (OSOW) permits to ensure safe transport of loads that exceed size and weight limits prescribed under state and federal laws. An OSOW permit is required when a vehicle or load exceeds legal sizes and weight limits and will be moved upon or across a highway or road or in Minnesota. Permits may include specific route instructions to limit risks and prevent damage to infrastructure by avoiding obstacles such as bridge tolerances, height clearances, weight limits, construction zones, and other safety concerns.
