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.

Future Java upgrades will not work with Online OSOW Permitting System

MnDOT’s online OSOW permitting system will not be compatible with any future versions of Java. To continue to use the online permitting system, you will need to avoid all future Java updates and instead continue to use version Java SE 8 and the Internet Explorer web browser.

For more detailed information and assistance with downloading Java SE 8, please see the Java SE 8 Guide to walk you through the steps.
