It is well known that elevated blood alcohol concentrations (BAC) negatively impact driving performance. However, it is not clear whether ascending and descending BAC differentially affect performance. The purpose of this study was to investigate the effects of ascending and descending blood alcohol concentrations on three particular motor tasks related to driving. This study measured performance on the motor tasks at BAC of 0%, 0.04%, 0.08% and 0.1%, as determined by a breathalyzer test. Reaction time was measured using a driving simulation system, the subject responded when brake lights on the monitor were illuminated. A Bassin Anticipation Timer was used to determine perception of an anticipated event coupled with effective motor responses. Lastly, the accuracy of a subjects perception of motor vehicle speed was determine using pre-recorded, two second video clips of cars driving at 30 and 45 mph on various roads.
