What does a cumulative score of 0 mean?

[MacBrady]

A cumulative score of 0 means no points have been deducted yet. Driving license point rules: Class C license: If 12 points are accumulated within a scoring cycle, the license holder must attend a training course at the vehicle management office as required, followed by an exam. The license can only be used again after passing the exam. For Class A and B licenses, accumulating 12 points within a scoring cycle not only requires attending training and passing an exam but also results in license downgrade. Driving license point deduction rules: Driving under the influence of alcohol, driving a vehicle that does not match the license type, or overloading a school bus will result in 12 points deducted at once; driving with a suspended license or violating traffic signals will result in 6 points deducted at once; driving below the minimum speed limit on highways or failing to undergo regular safety inspections will result in 3 points deducted at once; not driving according to regulations or engaging in behavior that hinders safe driving will result in 2 points deducted at once, etc.
