One study pointed to an average decreased reaction time of 120 milliseconds — just over a tenth of a second — associated with a BAC level of 0.08, the legal limit in the United States. So, when cruising at 70 miles per hour, a drunk driver would travel for an additional 12 feet before reacting to a roadway. This can result in a variety of impairments, including diminished concentration and judgment, a drop in vision of up to 32 percent, and a reaction time that's up to 25 percent slower, according to one report from the University of Texas at San Antonio.
