Drivers are considered to be alcohol-impaired when their blood alcohol concentration (BAC) is .08 grams per deciliter (g/dL) or higher. Thus, any fatality occurring in a crash involving a driver with a BAC of .08 or higher is considered to be an alcohol-impaired-driving fatality. The term driver refers to the operator of any motor vehicle, including a motorcycle. In 2007, 12,998 people were killed in alcohol-impaired-driving crashes. These alcohol-impaired-driving fatalities accounted for 32 percent of the total motor vehicle traffic fatalities in the United States. Traffic fatalities in alcohol-impaired-driving crashes decreased nearly 4 percent from 13,491 in 2006 to 12,998 in 2007. The alcohol-impaired-driving fatality rate per 100 million VMT decreased to 0.43 in 2007 from 0.45 in 2006. Estimates of alcohol-impaired driving are generated using BAC values reported to the Fatality Analysis Reporting System (FARS) and imputed BAC values when they are not reported. The term alcohol-impaired does not indicate that a crash or a fatality was caused by alcohol impairment. The 12,998 fatalities in alcohol-impaired-driving crashes during 2007 represent an average of one alcohol-impaired-driving fatality every 40 minutes. In 2007, all 50 States, the District of Columbia, and Puerto Rico had by law created a threshold making it illegal per se to drive with a BAC of .08 or higher. Of the 12,998 people who died in alcohol-impaired-driving crashes in 2007, 8,644 (67%) were drivers with a BAC of .08 or higher. The remaining fatalities consisted of 3,581 (28%) motor vehicle occupants and 773 (6%) nonoccupants. |
