Although under-rated as a cause of accidents, driver fatigue contributes to a large proporsion of the road deaths each year. A number of studies clearly indicate that the ability the driver to properly handle a vehicle decreases as fatigue increases. A driver that suffers from fatigue can be just as dangerous as a drunk driver.
The effect of driver fatigue can clearly be seen in cases where a monitoring sytem such as a tachograph or electronic fleet management system is installed on the vehicle. The sad part is that we usually examine this information after someone was killed in an accident. The driving pattern becomes erratic and usually the driver start to slow down. The reactions of the driver is slower. His ability to properly observe possible dangers is effected negatively. The driver could fall asleep, with no control over the vehicle.
