In this study of the effects of moderate blood alcohol levels (65 mg.%= .065%) on driver alertness, clinically normal individuals drove in an optical driving simulator for uninterrupted periods of 2 hours. During the alcohol session, subjects exhibited significantly slower reaction times, and indicated additional deleterious effects of the alcohol upon performance capacity. Results of this study suggest that the effects of moderate levels of blood alcohol must be examined not only as they affect simple perceptual-motor skills, but also as they may more subtly affect time-sharing capabilities and the various complex decision-reaction processes involved in operating a motor vehicle.
