Answer: In Illinois, the charge for a first offense DUI conviction is a Class A misdemeanor. In most cases, the second offense will also be considered a Class A misdemeanor. However, if you should have three DUI convictions, or if someone was seriously injured in your DUI accident, you will generally be charged with a Class 2 felony (or possibly a Class 3 or 4 Felony depending on the extent of bodily harm). Obviously, these are serious charges that have lifelong consequences and penalties. For more on Illinois DUI rules regarding misdemeanors and felnoies, see the Illinois state guide to DUIs.
