Driver fatigue is one of the significant contributing factors to traffic accidents, primarily manifested as delayed reactions, impaired judgment, and operational errors resulting from prolonged continuous driving, sleep deprivation, or diminished physiological functions. According to the latest regulations, driving continuously for over 4 hours without a break or with less than 20 minutes of rest constitutes fatigued driving. For passenger vehicles, driving continuously for more than 2 hours at night or accumulating over 8 hours of driving within a 24-hour period is also considered a violation. Moreover, high summer temperatures and the monotonous environment of highway driving can accelerate fatigue onset, while the driver's lifestyle habits, in-cabin conditions, and health status further influence fatigue levels. It is advisable for drivers to proactively take 15-minute breaks every 2 hours, refrain from long-distance nighttime driving, and maintain proper vehicle ventilation to mitigate risks.
