Determine if you need a permit
Generally speaking, you will need and oversize/overweight permit when vehicle and load dimensions exceed:
|Width||8’ - 6”|
|Height||13’ - 6”|
|Length||45’ - 0” (Single vehicles)
75’ - 0” (Combination vehicles)
A permit is not needed:
- When hauling utility poles (over-length only)
- Driving or towing implements of husbandry (e.g. farm equipment) at speeds less than 30 miles per hour. No interstate travel is allowed
- Through a governor's order or disaster relief
Pre-trip route survey
You will need a pre-trip route survey when an oversized load exceeds 16 feet high and/or 20 feet wide. You may also need a pre-trip route survey for excessive length.
Temporary weight increase permits
Having an oversize/overweight permit does not increase your vehicle’s registered weight. You can get a temporary weight increase permit from the Minnesota Department of Public Safety.
In general, you will need an escort vehicle when overall width exceeds 14' - 6" and under certain conditions.
