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 ]
Various studies have suggested that around 20% of all road accidents are fatigue-related, up to 50% on certain roads. [ 1 ] [ 2 ] Drowsiness can impair a driver’s mental stability, reducing their ability to make sound decisions and potentially leading to physical harm and financial losses for both the driver and passengers.
Fatigue impacts a driver's reaction time, awareness of hazards around them and their attention. Drowsy drivers are three times more likely to be involved in a car crash, and being awake over 20 hours is the equivalent of driving with a blood-alcohol concentration level of 0.08%. [147]
Particularly, somnolence is a recognized adverse effect of dopamine agonists, pramipexole and ropinirole. These drugs are known to cause sudden-onset sleep spells in roughly 50% of patients with Parkinson's disease (PD) while they were driving. [54]
During a normal season, the flu affects five to 20 percent of the population. That’s tens of millions of individuals in the United States alone. And the severity of the virus varies—some ...
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 ...
With drunk driving, drivers often experience the "looking but not seeing" phenomena. While their eyes do indeed view objects on the road, their brains do not comprehend the meaning behind the image. All levels of distraction while driving are dangerous, and potential drivers are cautioned to keep awareness of their surroundings. [2]
