Definition of Blood Alcohol Concentration (bac)

BAC or blood alcohol concentration is measured in weight per unit of volume. It is illegal in all states to operate a motorized vehicle with a blood alcohol concentration of 0.08% or higher. Blood alcohol concentration at this level affects the cognitive function of drivers and their ability to process information which can lead to increased injury and death from car accidents. Drivers who are arrested for driving under the influence may face high fines, mandatory alcohol education courses, probation, license revocation, or mandatory installation of an ignition interlock device.
