The Illinois legislature continues to create new ways to make DUI a felony offense. If you have two prior DUI convictions - you likely will face felony prosecution. If your license was suspended due to a prior DUI - you also will likely face felony prosecution. DUI can be a felony even where the motorist is a "first offender". For example, when a motorist is charged with a DUI and is uninsured or never actually obtained an Illinois Driver's License - a felony DUI prosecution may follow.
