North Dakota is one of the clearest cases where the Interstate figure understates the state limit: § 39-12-05 applies only to the Interstate system and matches the federal 20,000 / 34,000 / 80,000 baseline, while § 39-12-05.3 permits 105,500 lb gross on state highways. Off-Interstate axle rules also differ, allowing 19,000 lb per axle at some spacings. Dimensions are 102 inches by 14 feet.
