How many hours of driving require a 20-minute break?

[SarahLynn]

According to regulations, drivers who continuously operate a motor vehicle for more than 4 hours must take a break of no less than 20 minutes. Fatigued driving, which is highly likely to cause traffic accidents, refers to the phenomenon where drivers experience physiological and psychological dysfunction after prolonged continuous driving, resulting in an objective decline in driving skills. Poor or insufficient sleep quality for drivers, combined with extended periods of vehicle operation, can easily lead to fatigue due to a lack of endogenous oxygen. Below is an introduction to fatigued driving: 1. Overview: Fatigued driving refers to the phenomenon where drivers experience physiological and psychological dysfunction after prolonged continuous driving, leading to a decline in driving skills. 2. Hazards: It can affect a driver's attention, thinking, judgment, and other aspects, making it highly likely to cause traffic accidents. 3. Causes: There are multiple factors contributing to fatigued driving. The fatigue experienced by drivers is mainly due to neural and sensory organ fatigue, as well as limb fatigue caused by prolonged maintenance of a fixed posture leading to poor blood circulation.
