Abstract
Science evidence suggests that fatigue due to lack of sleep is a major cause of most traffic accidents. Fatigue can arise when people do not get enough sleep, which is at least 7 hours, and this deprivation can impair body performance physically and mentally while driving. This study investigated the effect of sleep deprivation fatigue on driving performance. Experiments were performed for two types of tasks, Fatigue driving tasks (sleep deprivation) and non-Fatigue driving tasks (without sleep deprivation) on a driving simulator at the University of Technology, in which 42 participants; aged (19-55) took part with an average age (mean = 33.14, SD = 10.26). Driver performance was assessed using descriptive methods to verify response time and subjective behavior methods using the Stanford Drowsiness Scale. The results showed a gradual increase in the average response time of the fatigued drivers compared to the non-fatigue drivers. The results of the response time indicated that all groups were affected by the test conditions, through the variation in the average response time between the two tasks. In a related context, the results of the Stanford Drowsiness Scale show a significant increase in the average degree of drowsiness for fatigue drivers, as it was greater than for non-Fatigue drivers.

It is clear that the level of alertness has changed dramatically for Fatigue driving compared to nonfatigue driving, and these results are consistent with the results of the researchers' findings [15], [18], [23]
Summary
Driving is a daily activity practiced by drivers around the world[1]–[3]. In general, requires important motor and cognitive skills, including the ability to visual space, memory, information processing, and rapid reaction, all of which involve mental stimuli. The literature sheds light on two broad concepts of wakefulness: first, the physiology of wakefulness and alertness, and second, information processing and sustained attention [5]. While there is a great deal of literature on the issue of alertness and its consequences for transportation activities, driver fatigue and drowsiness driving have received increased attention recently [6]. Driver fatigue is known to occur when driving requires sustained focus for an extended time [10] and has a direct effect on the driver's physiology while driving
