North Dakota Oversize Permits & Escort Information
WE ARE NOT A PERMIT SERVICE NOR DO WE ARRANGE PERMITS FOR CARRIERS. THIS IS STRICTLY JUST FOR INFORMATIONAL PURPOSES. WE DO NOT ENSURE THE ACCURACY OF THE BELOW INFORMATION SO BE SURE TO READ YOUR PERMIT SHEETS CAREFULLY!

Divisible Loads Exceeding 80,000: You can exceed 80,000 gross without a permit on state highways as long as you are legal on all axle/group weights and you are licensed for at least the amount of your gross weight. However, if you need any Interstate route, you will need to get an “Interstate Permit.”

Loads exceeding these dimensions or over 150,000 pounds are considered superloads.
Length: Over 120′ – 1 escort

SEASONAL LOAD (WEIGHT) RESTRICTIONS: Spring thaw load weight restrictions on non-Interstate highways go into effect some time in February and last into May and even much later on a few highways. Weight restrictions range from legal weight only to 8-tons, 7-tons and 6-tons per axle. Ton-mile exceptions are sometimes available, but they are very expensive.
SIGNS, FLAGS & LIGHTS: “Oversize Load” sign is required on rear of the vehicle when overall length exceeds 75′. All overdimensional loads must have flags on the traffic side of the load front and rear. Overwidth and overheight loads only require flags, not signs.
