How many kilometers can one drive continuously without it being considered fatigued driving?

[SamuelRose]

Continuous driving of a motor vehicle for more than 4 hours without stopping for a break or with a break time of less than 20 minutes is considered fatigued driving. Fatigued Driving: It is a serious traffic violation. When a driver is fatigued, their reaction time slows down, they may feel drowsy or sleepy, and their limbs may become weak, making it difficult to promptly detect road traffic conditions and take accurate driving control measures, which can easily lead to traffic accidents. Factors causing fatigued driving: are multifaceted. The fatigue experienced by drivers mainly involves neural and sensory fatigue, as well as physical fatigue caused by prolonged fixed postures and poor blood circulation. Drivers sitting in fixed positions for extended periods with limited movement, highly concentrated attention, and constant processing of external stimuli can lead to blurred vision, soreness in the back and waist, slowed reactions, and reduced driving agility.
