The report is the first of three annual reports to Congress on the safety impact of the 65 mph speed limit. The report indicates an increase of fatalities on all rural Interstate highways during calendar year 1987, but NHTSA emphasizes that with only one year of data, it is too early to draw any conclusions as to the long term effect of the increased speed limit on fatalities. There are substantial variations in state data; of the 38 states that raised the speed limit, 27 had an increase in fatalities during the time the increased speed limit was in effect in 1987 compared to the same time period in 1986, while 11 states had no increase, or a decrease in rural interstate fatalities. Likewise, of the 10 states that retained 55 mph, 6 remained unchanged or had a fatality increase in 1987 compared to 1986, and 4 had decreases. Collectively, the 38 states that raised their speed limit had a 19 percent average increase in rural Interstate fatalities. A large portion (64 percent) of the increase is from only 6 states. The 10 states that retained 55 mph also had an increase in fatalities on their rural Interstates of 7 percent.
