This four-way, dose-response, crossover, double blind, placebo-controlled, randomised validation study investigates the responsiveness of MedDrive, a computed battery of neuropsychological tasks, to different doses of alcohol. The following hypothesis are tested: 1. Measures from MedDrive are influenced by alcohol in a dose dependent way. 2. Effects of alcohol on driving performances are correlated to measures from MedDrive in a dose dependent way. 3. Within a group of healthy young drivers, MedDrive shows consistent results over repeated measures (ICC≥0.7). 4. MedDrive models effects of alcohol on driving performances better than does the UFOV or the trial making task.
