26-year comprehensive study is the first to measure reduced fatalities across many states
WASHINGTON, DC, July 24, 2007 -- State laws that require immediate suspension of the driver’s license for failing an alcohol breath test have had a deterrent effect on drunk driving and saved 800 lives from fatal crashes each year, new research shows. However, laws that suspend licenses or impose fines or jail sentences after conviction have little noticeable deterrent effect, according to one of the most comprehensive studies on the impact of drunk driving laws in the United States.
“The threat of immediate suspension of the driver’s license is a larger deterrent than the threat of more severe penalties that may occur at a later date. It has reduced fatalities from car crashes involving light, moderate and heavy drinkers,” according to study lead author Alexander C. Wagenaar, Ph.D., a professor of epidemiology at the University of Florida, College of Medicine.
