What are the factors contributing to driver fatigue?

[RichardAnn]

Fatigue driving refers to the phenomenon where a driver experiences physiological and psychological dysfunction after prolonged continuous driving, resulting in objectively observable decline in driving skills. There are five main causes of driver fatigue: 1. Living environment: Excessive distance between residence and workplace, heavy mental burden; 2. Sleep quality: Late bedtime, insufficient sleep duration, poor sleep quality, noisy sleeping environment affecting rest; 3. Vehicle environment: Poor air quality with inadequate ventilation, excessively high or low temperatures, severe noise and vibration, improperly adjusted seats; 4. Operating conditions: Extended duration or long-distance driving, excessively fast or slow speeds; 5. Driving experience: Low technical proficiency, unfamiliarity with operations, short driving history, limited experience, and poor safety awareness.

That time when I drove a long distance back to my hometown, I almost fell asleep on the road, and then I realized that fatigue driving should never be underestimated. Looking back now, it's mainly a sleep issue—many people stay up late scrolling through their phones or working overtime, and the next day their eyelids are heavy while driving. Driving continuously for more than 3 hours is especially dangerous. I once drove on the highway for 5 hours without a break, and in the end, my reactions slowed down. The weather also has an impact; if the car is too stuffy or if you've taken cold medicine, it's particularly easy to feel drowsy. Additionally, high life stress and constant anxiety can also distract you while driving. Now, I make sure to take regular breaks—every two hours, I must stop at a service area and walk around for a few minutes. After all, safety comes first.

Human physiological factors are at the core of fatigued driving. Sleep deprivation causes a sharp decline in brain alertness. Prolonged driving often leads to muscle stiffness and attention lapses, especially on monotonous highways where fatigue accelerates. Environmental factors cannot be ignored, such as oxygen-deprived conditions inside the car due to summer heat or drowsiness caused by antihistamines. I've also observed many professional drivers whose circadian rhythms are disrupted by shift work, requiring targeted adjustment strategies. It is recommended to assess one's condition through heart rate and reaction time tests, using scientific methods to mitigate risks.

In our car enthusiast group, we often discuss the issue of fatigued driving. Young people are most prone to falling victim to staying up late. Playing games until 3 AM and then driving to work the next day is like sleepwalking. Then there's having a few beers at dinner—even if you're not drunk, your body metabolizing the alcohol makes you especially tired. My buddy once zoned out on the highway during a long drive because of monotonous music. Here's a key tip: when your eyes start feeling dry, that's when it gets dangerous. Don't push through—switch drivers or pull over immediately. Relying on coffee for alertness has limited effect; the real solution is ensuring good sleep quality.

I feel the effects of driving more at my age. Last month, I drove to a neighboring city, and during the last half-hour of the three-hour trip, my neck was stiff, and my reaction time noticeably slowed down. As middle-aged and elderly people, our physical recovery ability declines, and driving continuously for two hours reaches our limit. Chronic conditions also have a significant impact; I occasionally feel dizzy after taking medication for my high blood pressure. The car environment requires special attention—once, the air conditioning broke down, and I was so stuffy that I was sweating profusely, almost missing the exit. Now, I've developed new habits: keeping cooling oil and a neck pillow in the trunk, always adjusting the seat angle before driving, and adding a small ornament to the rearview mirror to remind myself not to lose focus. Even short trips require caution.

A decade of driving trucks has given me the deepest understanding of fatigue behind the wheel. When freight orders pile up, you know you should rest but have to push through—especially on those grueling night shifts. Inverted circadian rhythms have tripped up many colleagues; by 3 or 4 AM, eyelids start battling on their own. Monotonous roads are deadly—driving through desolate provincial highways without a single tree in sight, staying alert only by pinching your thighs. Now I always teach apprentices two non-negotiable techniques: keeping sour candies handy to stimulate nerves, and mandatory tire checks every 150 kilometers to force movement breaks. Nutrition matters too—driving on an empty stomach is more dangerous than drunk driving.
