Find out if you need a permit
Generally speaking, you will need and oversize/overweight permit when vehicle and load dimensions exceed the following:
|Width||8' - 6"|
|Height||13' - 6"|
|Length||45' - 0" (Single vehicles)
48' - 0" (Mobile cranes)
75' - 0" (Combination vehicles)
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.
