Introduction to DUIs in Illinois
Currently in Illinois, there are 6 different charges for DUI. The most common is driving under the influence of alcohol. This offense can be charged in 2 separate ways. First, an individual may be charged with simply driving under the influence of alcohol. The second way is by charging an individual with driving under the influence of alcohol with a blood content of .08 or higher.
As to the first charge, the law states that a person is under the influence of alcohol when, as a result of drinking any amount of alcohol, his mental or physical abilities are so impaired as to reduce his ability to think and act with ordinary care. That definition does not require a significant amount of alcohol. In fact, all it requires is any as long as the state is able to prove beyond a reasonable doubt that the person was impaired and unable to act with ordinary care. The more common or what more well known charge of driving under the influence of alcohol is .08 or higher. That requires evidence that a persons whole blood has .08% of alcohol in it.
