Is driving at 100 km/h in an 80 km/h speed limit tunnel considered speeding?

Tunnel speed limit 80 driving to 100 is speeding, whether driving at 100 km/h in a highway tunnel constitutes speeding depends on the speed limit signs before entering the tunnel. Generally, the speed limit in tunnels is 80 km/h. Speeding refers to the driver operating a vehicle at a speed exceeding the legal or regulatory speed limit. Turbine overspeed accidents are major catastrophic incidents caused by faults in the turbine's speed control and protection systems, as well as inherent defects. Driving at 100 km/h on a road with an 80 km/h speed limit falls into the range of exceeding the speed limit by more than 10% but less than 20%. According to the new traffic regulations, for violations where the speed exceeds the limit by less than 50% on an 80 km/h speed limit road, traffic police will only issue a warning without a fine or penalty points. The dangers of speeding include an increased risk of rear-end collisions and rollovers. Increased risk of rear-end collisions: Data shows that on dry, level roads, the braking distance is approximately 70 meters at 80 km/h, 101 meters at 100 km/h, and 173 meters at 140 km/h! When the vehicle ahead brakes suddenly in an emergency, a following vehicle in the same lane traveling at excessive speed is highly likely to cause a rear-end collision. Increased risk of rollovers: Speeding deteriorates vehicle handling stability, especially when navigating curves, where centrifugal force can cause the vehicle to skid or tilt outward from the turning center. Excessive centrifugal force makes the vehicle extremely difficult to control, even leading to loss of control. On roads with low surface friction coefficients, this can result in skidding or collisions. On roads with high surface friction coefficients, it may lead to rollovers or other accidents.
I've been driving for decades and am very familiar with speed limit regulations in tunnels. The speed limit in tunnels is usually 80 kilometers per hour, and driving at 100 kilometers per hour is definitely speeding. Tunnels have special conditions: dim lighting, stale air, and very poor visibility. Driving too fast reduces reaction time, increasing the risk of rear-end collisions or hitting the wall. I remember once seeing a car lose control and overturn in a highway tunnel because it was going too fast, injuring several people. Nowadays, traffic regulations are strict: speeding over 20 kilometers per hour results in a fine starting at 200 yuan and significant demerit points. Speed limits aren't set arbitrarily; they're based on safety tests and accident data. I recommend keeping an eye on the dashboard while driving and not risking your safety and others' for a momentary thrill. Slowing down in tunnels is what smart drivers do.
As a frequent long-distance commuter, I must say driving at 100 km/h in an 80 km/h speed-limited tunnel definitely counts as speeding. I've done the math: speeding 20 km/h theoretically saves you just a few minutes, but getting caught by a speed camera means at least a hundred yuan fine plus penalty points; if an accident occurs, repair costs become a bottomless pit, and insurance rates will rise. The air in tunnels doesn't circulate well, emergency braking distances double compared to open roads - the risks are too high. Last time I passed through a tunnel during smoggy weather, driving fast nearly made me hit the car ahead, scaring me into a cold sweat. Nowadays cars come with navigation alert functions - set it up and it automatically beeps to remind you to slow down when speeding. Speed limits exist to ensure everyone's safety; it's not worth gambling your life and money to save a few minutes.
