Do I a need permit?
Legal dimensions are 8’6” wide, 14’ tall, 53’ length (tractor/trailer) 40’ single unit, and 75’ overall with a truck and trailer. You are also allowed 3’ of front overhang and 15’ of rear overhang.
If you exceed any legal dimension, you need an oversize permit. If you have a load that is heavy, exceeding what is allowed per the legal weight table (pdf 56kb) then you need a permit for weight.
If you need an overweight permit, you are required to have an Axle Spacing Report Number.
You can obtain an axle spacing report number by entering your vehicle combination information in the axle calculator. You will need the tire size of all two-tire axles and the distance between each axle (feet and inches). Once you have entered in the required information you can calculate and save to get your five-digit axle spacing report number. View our HELP menu if you need assistance.
What type of permit do you need?
There are various permit types, single trip oversize/overweight permits and even monthly/annual oversize permits. See permit types and applications.
