MnDOT makes change to Annual Permit Trip Logging requirement

Effective September 19th, 2016, trips made under a MnDOT annual permit will 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.

During this one-year trial period, 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 requirement change, see memo.

Check out the National Cooperative Highway Research Program Report on Multi-State, Multimodal, Oversize/Overweight Transportation

The Transportation Research Board’s National Cooperative Highway Research Program (NCHRP) Report 830: Multi-State, Multimodal, Oversize/Overweight Transportation is a compilation of existing permitting requirements for the transportation of oversize/overweight (OSOW) freight throughout the United States. It identifies and presents information about state-by-state differences in OSOW road transportation regulations and permitting practices, and the challenges these differences may pose for carriers. It discusses factors affecting modal competitiveness in OSOW transportation as well as opportunities for improved modal access.

The report also discusses ongoing and potential opportunities to improve information and procedural applications, covering the permitting process and the need for improved communication and coordination. For more information, download report.


Important regulations for parking at Minnesota's rest areas

Commercial vehicles cannot stop and park continuously in any of Minnesota’s MnDOT rest areas for a period longer than 10 hours, according to Minnesota Statutes 160.2721.

During inclement weather, the 10 hour restriction may be waived if a commercial vehicle must shut down due to the hazardous weather. Travel must resume when the weather event passes or at the direction of law enforcement. If you need to park at a rest area longer than the 10 hour limit for this or any other safety concern, please contact the rest area custodian and explain the situation to them so they are aware.

Please note that vehicles that park longer than 10 hours for reasons other than hazardous weather or safety concerns, may be subject to penalty. Also note that MnDOT rest areas cannot be used as staging areas or to drop trailers over long periods of time.

When parking at a rest area, please park vehicles in a manner that safely preserves the most number of truck parking stalls for others.

  • Required when oversized load exceeds 16’0” High  (previously required when exceeding 15’6”H)
  • Required when oversized load exceeds 20’0” Wide
  • May be requested for excessive length (case by case)

Additional information and requirements of the process are listed at the beginning of the new form.

Please begin using the new and improved Pre-Trip Route Survey form.
