Drivers with obstructive sleep apnea syndrome (OSAS) have an increased risk of motor vehicle crashes. Unfortunately, neither clinical nor polysomnographic features allow clinicians to reliably identify high-risk drivers. One potential means of identifying these drivers is with the use of driving simulators. Several investigators have shown that OSAS patients perform worse than healthy control d...

Motor vehicle crashes are the most common cause of serious head injury (Healthy People, 2002). Over the past decade, improvements to seat belts and frontal airbags have reduced the incidence and severity of injuries sustained in frontal crashes, but are less effective in side impact crashes. Prior studies have shown that both excessive linear and rotational accelerations are the cause of head i...

The proportion of motor vehicle crashes that involve a drowsy driver likely is greater than existing crash databases reflect, due to the possibility that some drivers whose pre-crash state of attention was unknown may have been drowsy. This study estimated the proportion of crashes that involved a drowsy driver in a representative sample of 47,597 crashes in the United States from 1999 through ...
