BAC refers to the amount of alcohol contained in a person's blood. It is measured as weight per unit of volume. Typically this measurement is converted to a percentage such as 0.10%, which indicates that one-tenth of a percent of a person's blood is alcohol. Because alcohol in the blood travels directly to the brain, cognitive functioning is affected, resulting in an increased risk of many kinds of injuries. Most significant among these is the risk of a motor vehicle crash when a person drives with too great a concentration of alcohol in his or her system. In North Carolina it is illegal to drive with a BAC of 0.08% or higher. On October 1, 1993 the legal BAC limit was reduced from 0.10%. All states have now lowered the legal limit to 0.08%, according to
