abstract="The effects of diazepam (10 mg) or caffeine (100 mg) was compared with placebo. Treatments were administered orally at weekly intervals according to a balanced design and under double-blind conditions. Each time one of the six female subjects drove for three hours on a motorway. Driving performance was estimated by a subsidiary reaction time (rt) task. It was found that the level of rt was significantly higher in the diazepam condition. A ten-minute rt-task before and after driving predicted the effect of diazepam. However, the subjects' own subjective experiences did not predict the deterioration in performance.
