Driving continuously should not exceed 4 hours. Here is relevant information: 1. Regulations: Article 62 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states that continuous driving of a motor vehicle for more than 4 hours requires a rest stop, with a minimum rest time of 20 minutes. Motor vehicle drivers must not drive continuously for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes. 2. Driving fatigue: Driving fatigue refers to the phenomenon where a driver's physiological and psychological functions become imbalanced after prolonged continuous driving, resulting in a decline in driving skills. Poor or insufficient sleep quality for drivers, combined with long hours of driving, can easily lead to fatigue. Driving fatigue affects various aspects of a driver's attention, sensation, perception, thinking, judgment, will, decision-making, and movement.

I've checked the traffic regulations. In our country, drivers must take at least a 20-minute break after 4 consecutive hours of driving, as it's a mandatory rule. This is because the human fatigue curve shows that reaction time decreases with prolonged driving, especially on highways where monotonous road conditions can easily cause drowsiness. I remember once on a long drive, after about 3 hours my eyelids started getting heavy, so I quickly pulled into a service area to rest and recover. Now I've developed the habit of proactively stopping at rest areas every 2-3 hours to drink some water and stretch, which is much safer than pushing through fatigue.

From a health perspective, it's really not advisable to drive for more than 4 hours. The human biological clock becomes less efficient after prolonged operation, especially in the afternoon and early morning when fatigue sets in easily. I once drove for 5 hours straight, and in the last half hour, I was purely relying on willpower to keep going—my braking reaction time noticeably slowed down. Doctors say the accident rate doubles after more than 3 hours of continuous driving. Now, I always bring a thermos with strong tea to stay alert or arrange for a friend to take turns driving. Remember, safety is no small matter—it's better to arrive late than to take risks.

I've been in long-haul transportation for over a decade, and industry regulations require shift changes after 4 hours of continuous driving. Once, I skipped rest to meet a loading deadline and nearly rear-ended the vehicle ahead. There's an old saying among truckers: 'Fatigue at the wheel is more dangerous than tire wear.' I'd advise regular drivers not to follow our professional habits—it's better to take a break every 2 hours. Always keep some cooling balm in the car to stay alert. If you must drive long distances, bring some peppermint candy to chew on; it helps maintain alertness.
