White Paper: Consequences of Drowsy Driving
period of time, and should not be relied upon to make up for a sleep deficit, studies show. As one researcher put it “Sleep debt can only be paid back with sleep.” (Nguyen et al, 1998)
There is no evidence that the alertness enhancing medicine modafinil can reduce drowsy driving. In one small study, in which sleep-deprived individuals were given the drug and then tested on a driving simulator, modafinil reduced lane deviation, but had less effect on speed deviation, off-road incidents and reaction time, while self-assessments indicated that the drug gave the sleep-deprived participants false confidence in their driving abilities. (Gurtman et al, 2008) There is also no evidence for anecdotal reports that opening car windows, stopping to stretch, or turning up the volume of a car radio can prevent drowsy driving crashes. (Nguyen et al, 1998)
Drowsy driving is a prevalent and serious public health issue that deserves more attention, education, and policy initiatives so a substantial amount of lives can be saved and disability averted due to drowsy driving accidents.
