The 2,336 fatalities that occurred in 1990 on rural Interstates in those 38 states that increased their speed limits to 65 mph in 1987 is 30 percent greater than might have been expected based on historical trends. The variation from the estimated trend projection is the same that occurred in 1988 and 1989. This suggests the fatality effect of the 65 mph speed limit has stabilized. The 1990 fatality rate for those states with a 65 mph speed limit, which includes the effect of the additional vehicle miles traveled on the rural Interstate system, has returned to the 1.4 fatalities per 100 million vehicle miles traveled level that existed in 1986, the last year of the 55 mph speed limit. While it is evident that rural Interstate fatalities have increased with implementation of the 65 mph speed limit, the rural Interstate remains the safest component of our nation's highway system. Rural Interstate fatalities represented only 6 percent of total traffic fatalities for 1990, numbering 2,701 nationally. The fatality rate on the rural Interstate system in 1990 was 1.3 per 100 million vehicle miles traveled, compared to 2.1 for the nation as a whole.
