Yes. In Illinois, the state’s blood alcohol limit of .08 only represents a presumption that you have been driving while intoxicated. While a breathalyzer reading below .08 can help disprove a presumption of drunk driving, it does not prevent the State from relying on other evidence such as slurred speech, inability to walk a line, glassy eyes and erratic driving.
The State, however, has the burden to prove a DUI beyond a reasonable doubt. An experienced attorney can help probe the weaknesses in the state’s case and improve your chances of obtaining a not guilty verdict.
