Is driving at 80 in a 70 speed limit zone a violation?

[DiLillian]

Driving at 80 in a 70 speed limit zone is a violation. Below are the specific details regarding road speed limits: 1. Penalty regulations: Exceeding the speed limit by less than 10% results in a warning without fines or penalty points; exceeding by 10%—20% incurs a fine and 3 penalty points; exceeding by 20%—50% incurs a fine and 6 penalty points; exceeding by more than 50% incurs a fine and 12 penalty points. 2. Speed excess percentage calculation formula: (Speed/Limit speed—1)*100, which calculates the speed excess percentage. For example, with a 70km/h limit and vehicle speed of 80km/h, divide 80 by 70, subtract 1, and multiply by 100 to get 14.28, meaning a 14% speed excess. If the limit is 60km/h and the vehicle speed is 70km/h, then divide 70 by 60, subtract 1, and multiply by 100, resulting in a 16% speed excess.
