Study says 2M drunken drivers on roads

An estimated 2 million intoxicated drivers with three or more convictions will be on the roads this holiday season, U.S. researchers said.

Researchers from the University of Missouri and the University of Georgia said that in 2007, about 1,500 people in the United States were killed in crashes that involved a drunken driver from Thanksgiving through New Year's Day.

The researchers measured the propensity to drink and drive of 6,000 respondents interviewed as part of National Highway Traffic Safety Administration's 2001 National Survey of Drinking and Driving Attitudes and Behavior.

The study, published in the Policy Studies Journal, found the majority of participants were less likely to drink and drive if they perceived a probability of being stopped or arrested by law enforcement. The study found that the most important deterrence factors for high-risk drivers are their perceptions of the likelihood of being stopped or arrested and their support for deterrence laws.
