Reductions in Alcohol-Related Traffic Deaths

In 2003, for the first time since 1999, the United States experienced a reduction in alcohol-related fatalities. There were 511 fewer alcohol-related traffic deaths in 2003, compared with 2002, which represents nearly a 3 percent reduction. Still, more than 17,000 people died in alcohol-related fatalities. How was this reduction accomplished and what is planned to reduce the numbers in the future?
