Abstract
A large scale review has been conducted of the experimental literature on alcohol effects on skills related to driving. This review considered 177 citations drawn from this literature, and explored the evidence of alcohol effects on reaction time, tracking, concentrated attention, divided attention performance, information processing capabilities, visual function, perception psychomotor performance, and also on driver performance measures. Impairment in all areas was significant by BACs of 0.05% and first appeared in many areas by 0.02% to 0.03%. Thus scientific evidence suggests no lower limit can be placed on alcohol impairment of driving-related skills. (A)
