What are the states and performances of drivers under different levels of fatigue?
2 Answers
Different levels of fatigue lead to different states and performances in drivers. Mild fatigue: Drivers may yawn frequently, have heavy eyelids, and experience untimely or inaccurate gear shifting; Moderate fatigue: Drivers tend to lose focus, have slower reactions, and sometimes even forget operations; Severe fatigue: Drivers often operate subconsciously or experience short periods of sleep, and may lose control of the vehicle in severe cases. Additional information is as follows: Driving fatigue refers to the phenomenon where drivers experience a decline in driving skills due to physiological and psychological dysfunction after prolonged continuous driving. Poor or insufficient sleep quality and long hours of driving can easily lead to fatigue.
When driving with mild fatigue, I often feel my eyes getting a bit dry, yawning more frequently, my attention starts to wander, and I keep thinking about listening to music or fidgeting, but I can still maintain basic steering wheel stability. With moderate fatigue, my reaction time slows down, such as hesitating for a second or two at traffic light changes, braking or accelerating less promptly, and sometimes getting easily distracted by things on the roadside. Severe fatigue is the most dangerous—my eyelids feel heavy as if they're fighting, my head keeps nodding, and I unconsciously drift out of my lane while driving, the car swaying back and forth, even forgetting to slow down for turns. These conditions all increase the risk of accidents, such as rear-end collisions or running off the road. I recommend opening the window for ventilation when experiencing mild fatigue, and for moderate to severe fatigue, it's essential to pull over and take a short nap—don't push through, safety comes first.
