Is driving at 120 km/h considered speeding on a highway with a 100 km/h speed limit?

On a highway with a speed limit of 100 kilometers per hour, if a motor vehicle reaches 120 kilometers per hour, it is considered speeding. Highways also have speed measurement sections, and speeding violations will be penalized. On highways, the maximum speed for small passenger vehicles cannot exceed 120 kilometers per hour, while other motor vehicles cannot exceed 100 kilometers per hour, and motorcycles cannot exceed 80 kilometers per hour. On highways: some sections have a maximum speed limit of 100 kilometers per hour, while others have a limit of 120 kilometers per hour. If you are driving in a section with a maximum speed limit of 100 kilometers per hour, any speed exceeding 100 kilometers per hour is considered speeding. If the speeding is within 10%: there will be no penalty points or fines, only a warning will be issued. However, if the speeding exceeds 10%, penalty points and fines will be imposed. Therefore, if the speed limit is 100, as long as you do not exceed 110, there will be no penalty points or fines. Exceeding 110 will result in fines and penalty points.

I remember when I first started driving, I also sped up to 120 km/h on the highway. Later, I got heavily fined and finally understood that driving at 120 km/h in a 100 km/h speed limit zone is a clear 20% over the speed limit. This level of speeding will result in a fine starting at 200 yuan and 6 points deducted from your driver's license. New drivers should pay special attention: accumulating 12 points during the probation period will lead to direct revocation of the license. In reality, a displayed speed of 120 km/h might only be around 115 km/h in actual speed, but this still doesn’t justify evading penalties. It’s advisable to use mobile navigation to confirm real-time speed, as fines are the least of your worries—emergency braking at this speed in rainy conditions could send you skidding over a hundred meters, which is truly life-threatening.

The displayed speed of 120 is not equal to the actual speed. Car speedometers have errors, and national standards allow them to be 3%-10% faster than the actual speed. Therefore, when the display shows 120, the actual speed may be between 114-116 km/h. Although this still exceeds the speed limit, fortunately, it won't trigger the second-tier penalty for exceeding the speed limit by 20%. The key is the calibration accuracy of the speed detection equipment, as some old radar speed detectors can have errors of up to 3%. It's recommended to compare with GPS speed using navigation software. However, no matter what, driving above 110 km/h falls into the category of dangerous driving.

When traveling with the whole family, it's even more important to control your speed. At a displayed speed of 120 km/h, the actual braking distance exceeds 100 meters, and can even reach 150 meters in rainy conditions. Luggage in the trunk can become projectiles during sudden braking, and the impact force on child safety seats doubles. A couple of days ago, I saw a car that had crashed into a guardrail at a service area. The owner said he was trying to overtake at 120 km/h when the car in front suddenly changed lanes, leaving him no time to react. Nowadays, most highways implement average speed monitoring, and exceeding the speed limit by more than 10% will trigger a warning text message.

According to traffic laws, exceeding the speed limit by more than 10% is punishable. If the displayed speed is 120 while the actual speed is 115, the calculation is: (115-100)/100=15%, which exceeds the 10% safety threshold. If the actual measured speed reaches 120, it constitutes a 20% overspeed, resulting in a fine of 200-2000 RMB plus 6 penalty points. Accumulating 18 points from three consecutive overspeed violations requires retaking the written test (Subject 1). Many provinces have introduced lane-specific speed limit rules, with stricter enforcement for overspeeding in the leftmost lane. It is advisable to maintain a speed below 108 km/h in daily driving to account for speedometer errors.

Veteran driver with 10 years of experience shares tips: Driving at 120 on a 100-speed-limit road will definitely get you a ticket! Currently, speeding enforcement is divided into three tiers: exceeding 10% results in a warning, exceeding 20% incurs a 200-yuan fine and 6 penalty points, and exceeding 50% leads to immediate license revocation. Once I was caught at 118 km/h, though my actual speed was only 112 km/h, and was penalized for 17% over the limit. The most dangerous are long downhill sections where speed can creep up unnoticed. Remember, all tunnels are hotspots for speed cameras, and you should slow down before curves. If you're in a hurry, it's better to leave earlier—only safety ensures you get home.
