The Insanity of Drive-55 Laws - WSJ.com

Mr. Warner repeats the myth that a lower federal speed limit will increase traffic safety. Back in 1995, Naderite groups argued that repealing the 55 mph limit would lead to "6,400 more deaths and millions more injuries" each year. In reality, National Highway Traffic Safety Administration data reveal that in the decade after speed limits went up (1995-2005), traffic fatalities fell by 17%, injuries by 33%, and crashes by 38%. That's especially significant because in 1995 far fewer drivers were gabbing on their cell phones or text messaging while driving.

In a study for the Cato Institute in 1999, I compared the fatality rates in states that raised their speed limits to 70 mph or more (mostly in the South or West) with those that didn't (mostly in the Northeast). There was little difference in safety. Of the 31 states that raised their speed limits to 70 mph or more, only two (the Dakotas) experienced a slight increase in highway deaths. The evidence is overwhelming that traffic safety is based less on how fast the traffic is going than on the variability in speeds that people are driving. The granny who drives 20 mph below the pace of traffic on the freeway is often as much a safety menace as the 20-year-old hot rodder.
