Impairment due to combined sleep restriction and alcohol is not mitigated by decaying breath alcohol concentration or rest breaks

Epidemiological and laboratory-based driving simulator studies have shown the detrimental impact of moderate, legal levels of alcohol consumption on driving performance in sleepy drivers. As less is known about the time course of decaying alcohol alongside performance impairment, our study examined impairment and recovery of performance alongside decaying levels of alcohol, with and without sleep restriction.Sixteen healthy young males (18-27...
