ScienceDaily (July 18, 2009) — The repeal of the federal speed control law in 1995 has resulted in an increase in road fatalities and injuries, according to researchers at the University of Illinois at Chicago School of Public Health.
The research is published in the September issue of the American Journal of Public Health. It is the first long-term study to evaluate the impact of repealing the National Maximum Speed Law on road fatalities and injuries in fatal crashes between 1995 and 2005.
The law, which restricted the maximum speed limit to 55 mph on all interstate roads in the United States, was initiated in 1974 in response to the oil embargo and had an immediate impact.
"During the first year there was a drop of almost 17 percent in fatalities after the speed laws were reduced to 55 miles per hour," said Lee Friedman, assistant research professor of environmental and occupational health sciences at UIC and lead author of the study.
The law was modified in 1987 and allowed states to raise the legal speed limits to 65 mph on some interstates. In 1995, the federally mandated 55 mph speed law was revoked, allowing states to set their own speed laws.
"The primary finding of our study was that over the 10-year period following the repeal of National Maximum Speed Law, there were approximately 12,500 deaths due to the increased speed limits across the U.S.," said Friedman.
