The goal of the Illinois DUI process is to prevent another DUI arrest. One way of achieving that goal is through punishment. That’s the fines, the jail time, the probation and so forth.
The second means is through rehabilitation. The thinking is that if you have a DUI, you may have a drinking problem. If you do not fix the drinking problem, you are at risk to receive another DUI.
You may need outside help. The type of help you need will depend upon the severity of your problem.
If you are arrested for DUI in Illinois and are considered an appropriate candidate for court supervision, before the judge can sentence you to supervision, you must obtain a drug and alcohol evaluation from a facility licensed by the Division of Alcoholism and Substance Abuse (DASA) These evaluating agencies will interview you about your drinking and drug habits and ask other questions designed to determine what types of problems alcohol or drug use have caused in your life apart from the DUI.
If you are not eligible for court supervision and are found guilty of the DUI, you are not required by law to obtain an evaluation but many judges will demand one anyway. Furthermore, upon being convicted of the DUI, you will lose your license and have to have a Secretary of State hearing. At such a hearing, you must produce an evaluation and other documents.
