What does the white 80 road marking mean?

[Adalynn]

The white 80 indicates a minimum speed limit of 80. Below is a detailed introduction to speeding penalties: Exceeding the speed limit by less than 10%: 3 demerit points. Exceeding the speed limit by more than 10% but less than 20%: 3 demerit points. Exceeding the speed limit by more than 20% but less than 50%: 3 demerit points. Exceeding the speed limit by more than 50% but less than 70%: 6 demerit points, and the driver's license may also be revoked. When speeding, drivers cannot fully and accurately perceive changes inside and outside the vehicle. It weakens the driver's spatial awareness and reduces their ability to judge speed.
