How does the driver license point system work?

Driver license points - frequently asked questions
My citation says four points; your letter says eight. Why?
The point value noted on the citation is an "estimated point value". The violation for which you are finally convicted and the license type you hold at the time of conviction determine the points assessed against the driving record.
If you hold a probationary license, instruction permit, or no license when the conviction is entered on the record, points will be doubled for any second and subsequent convictions, except for convictions under Chapter 347 of the Wisconsin Statutes, which are primarily vehicle equipment violations.
How many points do I have left?
If you accumulate 12 or more demerit points in any 12-month period, a suspension will result. Individuals with a clear driving record have 0 points. Points are assessed for moving traffic convictions based on the violation offense date. When determining points, be sure to include any pending citations or convictions which do not yet appear on your record.
I have tickets pending. How will this affect my driving record?
The violation date (not conviction date) determines whether you have accumulated 12 or more points in any 12-month period. If you are convicted of any pending violations the points will be counted based on the date of violation. If your conviction(s) result in the accumulation of 12 or more demerit points for violations within any 12-month period, a suspension will result.
Can I hold a ticket open so there will be more than one year between convictions?
Since the determination of your point total is based on violation date and not conviction date, there is no advantage in doing so.
Points are no longer counted against me after one year, but if there is a pending ticket, will the violation date be used?
As long as convictions remain on the driver record, the points for those convictions remain available to determine whether 12 or more points have accumulated in any 12-month period. The violation dates, not the conviction dates, are used in that determination.
For example: you receive a traffic citation and do not go to court for two years. When the court does report the conviction, points are counted from the date of the violation. If the conviction causes you to accumulate 12 points in any 12-month period, your operating privilege will be suspended.

Is there a way to reduce my points?
If you have completed an approved Traffic Safety course, you can request a 3-point reduction of your demerit point total. The point reduction must be claimed before the accumulation of 12 or more points in any 12-month period. No point reduction is permitted if you have already accumulated 12 or more points, which resulted in a suspension of your driving privilege. You can also request a 3-point reduction upon completion of a motorcycle rider course. (This point reduction only applies to violations and convictions incurred while operating a motorcycle.)
Courses can be taken as often as you wish, however you can receive only one point reduction every 5 years.
Can I take a traffic safety course after I'm suspended for accumulating 12 or more points?
Yes, but no point reduction would be permitted and the suspension would stand. A reduction of up to 3 points would be applied after reinstatement of the operating privilege if points exist.
Is a zero point total good or bad?
It helps to remember that these are demerit points. Therefore, you do not want to have points. All drivers with a clear record have zero points. As you accumulate convictions, you accumulate demerit points. If you accumulate 12 or more demerit points in any 12-month period, your driving privilege will be suspended.
