Find out if you need a permit
Generally speaking, you will need an oversize/overweight permit when vehicle and load dimensions exceed the following:
| Dimension | Size/Weight |
|---|---|
| Width | 8' - 6" |
| Height | 13' - 6" |
| Length | 45' - 0" (Single vehicles) 48' - 0" (Mobile cranes) 75' - 0" (Combination vehicles) |
| Weight | 80,000 lbs. |
A MnDOT permit is not valid on county, municipal, township or other local roads.
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.
