Any first offense for which you qualify for ARD, you are eligible for an expungement in the state of Pennsylvania.  However, in Delaware County, you are required to file a petition for expungement.  If you fail to do so, your DUI or any other crime may stay on your record. As such, schools and/or future employers will still be able to view any prior infractions on your record.  Be sure to follow up on this after your completion of ARD.
