I recently had a background check done for a job. I got the job, but realized I'd like to clean up my record. The question is: I have an arrest in Cook County for DUI in which the DUI was dropped but I pled guilty to misdemenor leaving the scene of an accident (Oct 2003), I also have an arrest for assault in Coles County from 1993, in which the charges were dropped. 1. If I want to expunge these, do I have to go through each county separately? 2. Can I also expunge the leaving the scene if I got supervision, or is that considered a traffic violation that is ineligible?
