  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.
