How much over the average speed in a speed zone will result in a traffic violation?

No penalty will be imposed for speeds within 10% of the prescribed limit, but exceeding 10% and below 20% will result in penalties. Algorithm for speed zone violations: The speed zone monitoring system involves setting up two cameras at adjacent monitoring points on the same road section to establish a monitoring and capture system. This system conducts two real-time monitoring captures of vehicles passing through the monitored area, obtaining information such as vehicle speed, traffic volume, license plate number, color, approximate physical dimensions, and driver characteristics. The data is then transmitted via a network to the databases of the public security traffic command center and traffic control sub-centers for storage, querying, comparison, and other processing. Penalty standards for speed zone violations: On roads with speed limits below 50 km/h, exceeding the speed limit by more than 10% but less than 20% will result in a fine; exceeding by more than 20% but less than 50% will also result in a fine. Exceeding by more than 50% but less than 70% will incur a fine, and exceeding by more than 70% will lead to a fine.
The principle of interval speed measurement is to record the time difference between your passing the start and end points to calculate the average speed. As long as this average speed exceeds the speed limit indicated on the road signs, it is considered a violation. For example, on a road with a speed limit of 80, if you take 20 minutes to complete 40 kilometers, your average speed is 120, which means you exceeded the limit by 40 km/h. The key point is that the actual speed limits vary by region: highways might have a limit of 120, while regular roads could be 80 or 60. A common misconception is that drivers think speeding in the first half and slowing down in the second half can fool the system. In reality, as long as the average speed exceeds the limit, it will trigger the violation photo system. It is recommended to use cruise control throughout the journey and check the dashboard when entering and exiting speed measurement zones to avoid letting momentary speeds raise the average.
I just got caught by an average speed check on the highway last month. The speed limit was 120 km/h, but I drove at 140 km/h in the first half and only slowed down to 100 km/h when I saw the camera at the end, thinking I could balance it out. A few days later, I received a ticket showing my average speed was 128 km/h. Turns out, the speed monitoring system starts timing as soon as you enter the zone, leaving no room for loopholes. Penalties vary depending on the road type and the extent of speeding—for instance, exceeding the limit by less than 10% on highways might only warrant a warning, while going just 5 km/h over on regular roads could lead to a fine. It's best to plan your route with navigation in advance and ease off the accelerator as soon as you see the 'average speed check ahead' warning.
