The National Highway Traffic Safety Administration (NHTSA) defines drivers as alcohol-impaired “when their blood alcohol concentration (BAC) is 0.08 grams per deciliter (g/dL) or higher [and] any fatal crash involving a driver with a BAC of 0.08 or higher is considered to be an alcohol-impaired-driving crash, and fatalities occurring in those crashes are considered to be alcohol-impaired-driving fatalities” (NHTSA DOT HS 811 700, 2012, p. 1). Alcohol-impaired driving in the United States in 2011 (latest data available) resulted in 9,878 deaths, or 31 percent of all motor vehicle traffic fatalities.
In 2012, Indiana had 158 alcohol-impaired driving fatalities (a 12.9 percent increase from 140 fatalities in 2011) and 2,112 injuries. This fact sheet presents information on alcohol-impaired traffic collisions in Indiana between 2008 and 2012. It examines Indiana’s comparative status among other Great Lakes states, different dimensions of alcoholimpaired collisions, the general incidence of alcohol testing, the BAC test results for involved drivers, and other attributes of alcohol-impaired collisions, injuries, and fatalities reported in the Indiana State Police Automated Reporting Information Exchange System (ARIES), as of April 9, 2013.
