How much is the percentage of speeding when driving at 135 km/h in a 120 km/h speed limit zone?

[MacWilliam]

Driving at 135 km/h on a highway with a speed limit of 120 km/h means speeding by 12.5%, which will result in a fine and 3 demerit points. When a motor vehicle violates speed limit regulations on the road, the latest speeding fine and demerit point standards apply. The fines and demerit points for speeding by ordinary vehicles are as follows: 1. Speeding <30%: No penalty for exceeding the speed limit by less than 10%; exceeding the speed limit by more than 10% but less than 20% results in a fine and 3 demerit points; exceeding the speed limit by more than 20% but less than 30% results in a fine and 6 demerit points. 2. Exceeding the speed limit by more than 30%: Exceeding the speed limit by more than 20% but less than 30% results in a fine and 6 demerit points; exceeding the speed limit by more than 50% but less than 70% results in a fine and 12 demerit points, and may also lead to license suspension; exceeding the speed limit by more than 70% results in a fine and 12 demerit points, and may also lead to license suspension. On roads with a speed limit below 60 km/h, speeding by less than 50% results in a warning.
