The NMA supports speed limits that are based on the 85th percentile rule of traffic engineering in which the limits are set within 5 mph of the free-flowing speed at which 85 percent of traffic is traveling. If North Dakota has determined that 75/80 mph are these speeds, studies have shown the roads will be a safe, if not safer, with limits that promote natural, consistent travel speeds.
