MnDOT makes change to annual permit trip logging requirement permanent

Trips made under a MnDOT annual permit no longer require a route pre-approval through MnDOT's permitting system whenever the loaded vehicle does not exceed the following dimensions:

  • 11'0" Wide;
  • 14'6" High; or
  • 110'0" Long.

MnDOT strongly encourages using its permit routing system to verify all routes, but it is no longer a requirement when loaded dimensions are within those listed above.
Loads exceeding the dimensions listed above, and overweight loads, are still required to obtain route pre-approval from MnDOT.
For complete details about this permanent requirement change, see memo.
