What is the maximum percentage by which you can exceed the speed limit on the highway?

[DanielaLee]

Speeding will result in certain penalties, so it's best not to exceed the speed limit. Highways are high-grade roads designed for vehicles to travel at high speeds with controlled access, and they prohibit pedestrians and non-motorized vehicles. The average annual daily traffic volume for passenger cars is over 25,000. The penalties for speeding are as follows: 1. Vehicles exceeding the speed limit by less than 10% on the highway will not be fined or penalized with points, but will receive a warning. 2. Exceeding the speed limit by more than 10% but less than 20% will result in a fine of 50 yuan and 3 penalty points. 3. Exceeding the speed limit by more than 20% but less than 50% will result in a fine of 200 yuan and 3 penalty points. 4. Exceeding the speed limit by more than 50% but less than 70% will result in a fine of 1,000 yuan and 6 penalty points. 5. Exceeding the speed limit by more than 70% will result in a fine of 2,000 yuan, 6 penalty points, and revocation of the driver's license.
