Wis. Admin. Code Department of Transportation Trans 101.03
Under Graduated Driver Licensing, few drivers receive warning letters before being suspended for demerit points. This is because ch. 343, Stats., has reinstated point doubling. A probationary driver with any prior violation on his or her record who is convicted of a 6-point violation will be assessed 12 points for that offense and be immediately suspended. Similarly, a driver who accumulates two 4-point offenses will be summarily suspended without warning. The first 4-point ticket will not trigger a warning under this rule. The second 4-point ticket will result in an 8-point assessment after doubling, resulting in a total of 12 demerit points and a suspension.
