Samenvatting
This report outlines the biology of human sleep and sleepiness which physiologically underlies crash risk; common characteristics of crashes related to drowsy driving and sleepiness; risks for crashes attributed to drowsy driving; population groups at highest risks; and effective countermeasures used to prevent drowsy driving and related crashes. In addition to summarizing what is known - and what remains unknown - from sleep and highway safety research, the report also presents the panel's recommendations for the highest priority target audiences and message points for the NCSDR/NHTSA educational campaign.
