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.
