Dozer blades that are over-width must removed and are allowed to be hauled with the dozer on same trailer even if the blade makes the shipment overweight. Make sure that you tell the ODOT permits office that you are shipping a dozer so they document it on your permit. For annual permits that are over-length and over-weight 48′ trailers are permitted to travel on some length restricted highways. Highway 395 from Pendleton, OR to John Day, OR is a good example as well as and highway 25 which spans the entire state will allow some divisible loads that exceed 80,000 pounds. These types of permits can be obtained from the Port of Entry or from the Oregon DMV for $8. Simply contact them at any of the offices listed below. If you are shipping anything overweight or oversize in Oregon you want to refer to the  Oregon State informationissued guide  for more detailed information. This is pretty much a must read for shipping in this state, especially if you are transporting items through the state off of I-5.

Oregon superload information:

Length: Loads that are over 150 in length are considered superloads.

  1. Time of 2pm on Christmas eve for oversize is not correct it is 12:01pm

  2. Thanks for saying that loads that are over 150 in length are considered superloads by the state. I’m guessing that these types of loads will need overweight permits if they are going to be transported by commercial trucks. My brother wants to become a trucker someday, so I’m helping him orient himself with the laws that are needed for a trucking business, so he may find this information useful.

  3. Any permits issued are only for transport within the state issued by.
