Effects of Low Doses of Alcohol on Driving-Related Skills: A Review of the Evidence

A large scale review of the experimental literature on alcohol effects on skills related to driving, considered 177 citations 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. /Abstract from report summary page/
