North Dakota Truck Following Distance

No fixed number for you. Out on the open road behind another truck or a combination, leave enough room for a passing car to slip in — 'sufficient space,' not a set distance (N.D.C.C. § 39-10-18(2)). Behind a car or anywhere in town it's reasonable and prudent (§ 39-10-18(1)), and that's the tailgating ticket, a $20 noncriminal fee. The separate 500-foot rule is only for trailing an emergency vehicle (§ 39-10-57), not a general limit.
