Forgot you are in WI.
Court supervision is like a second chance, if you go the whole length of the supervision and don't get ANY tickets whatsoever, the original charge is usually dropped.
Im on 3 month court supervision because I recieved too many tickets in a 12 month period, if I get charged with my most recent speeding ticket my license will be suspended.
Anyone that i know who got a dui in IL ended up paying $3-7k in court costs and lawyer fees. First offense.
