abstract="OBJECTIVES: We assessed the 5-year, nationwide impact on road deaths of the raise in the speed limit (November 1, 1993) on 3 major interurban highways in Israel from 90 to 100 kph. METHODS: We compared before-after trends in deaths as well as case fatality-an outcome independent of exposure (defined as vehicle-kilometers traveled). RESULTS: After the raise, speeds rose by 4.5%-9.1%. Over 5 years, there was a sustained increase in deaths (15%) and case fatality rates (38%) on all interurban roads. Corresponding increases in deaths (13%) and case fatality (24%) on urban roads indicated &quot;speed spillover.&quot; CONCLUSIONS: Immediate increases in case fatality predicted and tracked the sustained increase in deaths from increased speeds of impact. Newtonian fourth power models predicted the effects of &quot;small&quot; increases in speed on large rises in case fatality rates. Countermeasures and congestion reduced the impact on deaths and case-fatality rates by more than half.",
