Research has generally focused on pilots, truck drivers, and shift workers. Fatigue can be a symptom of a medical problem, but more commonly it is a normal physiological reaction to exertion, lack of sleep, boredom, changes to sleep-wake schedules (including jet lag), or stress.
The HOS's main purpose is to prevent accidents caused by driver fatigue. This is accomplished by limiting the number of driving hours per day, and the number of driving and working hours per week. Fatigue is also prevented by keeping drivers on a 21- to 24-hour schedule, maintaining a natural sleep/wake cycle (or circadian rhythm). Drivers are ...
One example is that drivers classified as obese were significantly more likely to be rated as fatigued, to be involved in a safety-critical event, and to be involved in safety-critical events related to fatigue. [18] Another naturalistic driving study of local and short-haul truck drivers found that 8 of the 42 drivers in the study accounted ...
Sleep-deprived driving (commonly known as tired driving, drowsy driving, or fatigued driving) is the operation of a motor vehicle while being cognitively impaired by a lack of sleep. Sleep deprivation is a major cause of motor vehicle accidents, and it can impair the human brain as much as inebriation can. [ 1 ]
During these two time periods drivers are more likely to become drowsy, which increases the chance of accidents. [4] Statistics show that a leading cause of fatal or injury-causing traffic accidents is a diminished vigilance level. In the trucking industry, 57% of fatal truck accidents are due to driver fatigue.

The relationship between number of hours driven and the percent of commercial truck crashes related to driver fatigue is an exponential relationship. (See graph.) Although the accident rate per 100 million miles for professional truckers is low, the high number of miles driven by a truck driver makes truck driving a risky occupation.
