A single trip oversize/overweight permit is required for a non-reducible oversize and/or overweight load movement that exceeds North Dakota legal vehicle size and weight limits. See the ND Legal Vehicle Size and Weight Guide and the ND Weight Limitations Chart for further information.

The online system (E-Permits) accepts single trip permit for all oversize/overweight load movements. Axle weights shall not exceed maximum permitted limits. See the Permit Policy for Movement of Oversize and Overweight Vehicles and/or Loads for further information. The maximum weight on a tandem axle is 40,000 lbs. and a single axle is 22,000 lbs. when the GVW exceeds 150,000 pounds.

A single trip permit is valid for one load movement up to five days.
