Using U.S. government data, the Traffic Injury Research Foundation found that high-Blood Alcohol Content (BAC) drivers tend to be problem drinkers, and they are more likely than other drivers to have a history of drunk-driving convictions and driver's license suspensions related to drunk-driving. Seventy-eight (78) percent of drunk drivers killed in 1988 consumed large amounts of alcohol -- the equivalent of seven or eight drinks in an hour for a 160-pound person, reaching blood alcohol content (BAC) levels of .15 percent or above. In addition, the study found that:
Nearly 8,500 high BAC drivers are killed on our nation's roads each year. This is nearly one-third of all drivers, drinking or non-drinking, killed in the U.S.
High-BAC drivers make up only 1 percent of drivers on the road on weekend nights, but they constitute half of all drivers killed. They are more than 200 times likely to be involved in a fatal crash than non-drinking drivers.
