How does Wisconsin's point system work?

Demerit points are assessed to drivers when convicted of a moving violation, beginning on the date of the violation.
The courts send the Wisconsin Department of Transportation (WisDOT) Division of Motor Vehicles records of all convictions for moving traffic violations.
Persons who hold a probationary license are assessed double points for the second and all subsequent points.
When 12 or more demerit points are accumulated in one year, a suspension of the driver privilege is required, for a minimum of two months.
Convictions remain on the driver records for five years from the date of conviction. However, alcohol related and some commercial violations remain on the record for 10 years to life.
Reducing points
The point total may be reduced by three points for attending an approved traffic safety course.
Only one reduction is allowed in a five year period for points assessed to the A, B, C, D classification.
One reduction of three points is also allowed in a five year period for points assessed for class M (Motorcycle) violations.
No point reduction is permitted if in one year a person accumulates 12 or more points which would require suspension.
