Details are given of a series of tests in the laboratory and on the road with subjects having different levels of blood alcohol content. The results showed that alcohol significantly increases both simple and choice reaction times, course steering reversals in both choice and simple reaction time treatments, whereas it significantly decreases the time on-target in both choice and simple reaction time treatments. Attention is drawn to the fact that the influence of alcohol will proportionally be greatest on the learner driver since his already limited capability for timesharing will be further reduced by alcohol.
