North Dakota has increased weights (to 105,500 lbs) available over a comprehensive state road network. Permits for increased weights to 105,500 lbs are also available for the interstate. Additionally, LCVs are allowed on a very large network as well as other double combination trailers that can have a cargo carrying length of up to 68’. This means that tridem trailers are common throughout the state, as well, a tridem can carry 48,000 lbs on non-interstate roads. Trucks that are operated in North Dakota include B trains and semi trucks with a tridem drive, and tridem axles on the trailer. These heavier trucks serve the well-known boom in the North Dakota oil patch as well as the agricultural industry.
