What does a Canadian farmer need in order to haul product in North Dakota?

Saskatchewan or Manitoba farmers hauling their own farm product on farm registered license plates in an interstate operation are exempt from trip permits, but a fuel permit is required.  A fuel permit is $15 and valid for 72 hours or when the vehicle leaves the state, whichever occurs first.  Fuel permits may be purchased online.

Manitoba farmers hauling or gainfully employed intrastate within 20 miles of the border are exempt from registration but would need a fuel permit.
