The economic development of modern society requires continuous improvement of transport and their efficiency throughout the span of 24 hours. Drowsiness may be a serious risk to the safety of employees, passengers and third parties. Sleepiness at the wheel is responsible for 5% to 30% of road accidents. Several pathophysiological factors governing the driving skills were studied: lifestyles, work schedules, prolonged wakefulness, stress, and sleep disorders. Screening of sleep disorders and education of workers at a proper sleep hygiene are fundamental keys to the safe transport. The individual initiatives to reduce the risk of drowsiness should be framed in a more general safety effort of the institutions.
