Truck drivers face enormous pressure to travel long distances in a short amount of time. As a result, truck drivers can face an incentive to work long hours, even when they are so tired that they pose a risk to themselves or other drivers on the road. For this reason, the Federal Motor Carrier Safety Administration and other agencies have rules in place that limit the amount of time truck drivers can be on the road without rest.
Another factor that can lead to dangerously fatigued driving is a sleep disorder. Obstructive sleep apnea is a disorder that will cause disruptions in sleep and lead to fatigue during daylight hours. The American Academy of Sleep Medicine has argued that the absence of a test to determine whether a driver is suffering from sleep apnea can lead to serious injury and fatalities due to a truck crash. The FMCSA, in association with the Federal Railroad Administration issued a notice that the agencies are seeking to change the current rules for drivers to receive tests, evaluations and treatment for the disorder.
