How is fatigue driving on highways determined?

Continuous driving of a motor vehicle for more than 4 hours without stopping for rest or with a rest period of less than 20 minutes is considered fatigue driving. Below are the penalties for fatigue driving: 1. Medium and large-sized passenger vehicles: If driving a medium or large-sized passenger vehicle or a vehicle transporting hazardous materials, a fine of 200 yuan will be imposed, along with 12 demerit points. 2. Non-medium and large-sized passenger vehicles: If driving a non-medium or large-sized passenger vehicle or a vehicle transporting hazardous materials, a fine of 200 yuan will generally be imposed, along with 6 demerit points. 3. Causing an accident: If a major traffic accident occurs due to fatigue driving, violating criminal law, the driver will bear corresponding criminal responsibility.

During long-distance drives, I often observe signs of fatigue on the highway. The key indicators are physical signals and vehicle behavior: if you're constantly yawning, your eyelids are heavy, or your vision is blurring, those are fatigue warnings; if your car shows unstable steering control, like lane drifting or inconsistent braking, traffic police will spot these anomalies through surveillance cameras and pull you over if detected. Technology also helps—in-car systems monitor blink frequency or head position and sound an alarm if you close your eyes too long. On highways, you should take a break every two hours of continuous driving. Fatigued driving is extremely risky—I once nearly missed an exit due to a brief doze, so now I make it a habit to check my alertness regularly. Overall, prevention beats detection: getting enough sleep before departure and taking frequent breaks to stretch your legs can avoid most issues.

As a commuter who frequently drives on highways, I believe determining fatigue driving should combine subjective feelings and objective changes. Personally: lack of concentration, frequent eye rubbing or yawning indicate tiredness; in terms of the vehicle, steering wheel wobbling, uneven speed or slow response are all danger signals. Highway enforcement uses intelligent systems to scan driving trajectories, triggering intervention if lane keeping is poor—I've been warned before. For prevention, setting trip reminders is crucial, such as stopping to stretch every 1.5 hours. Fatigue driving easily leads to rear-end collisions with serious consequences, so early detection is a must. Staying hydrated and taking short breaks help a lot, and I carry energy snacks for emergencies. Simply put, listening to your body and acting promptly is the most reliable.

Highway fatigue driving detection relies on a combination of human senses and technology. Individuals may notice heavy eyelids, distracted thoughts, or frequent yawning, while unstable vehicle movements can be observed by traffic police through surveillance. Modern vehicles are equipped with fatigue detection systems: sensors track facial movements and trigger alarms if eyes remain closed for too long, while smart navigation also assists in analyzing lane deviations. Highway patrols often use this data to intercept high-risk vehicles. Prevention is crucial—taking timely breaks helps avoid accidents. I always set a driving schedule to stay alert and ensure safety.
