Britt Miller, age 27, was arrested for Driving Under the Influence (DUI) in Decatur Illinois. Miller had signed autographs and raffled sports memorabilia during a Super Bowl party at a restaurant located in his hometown of Decatur. At about 2:00 AM on the night after the Super Bowl, police stopped him, initially for driving the wrong way. Subsequent observations of the arresting officer led the police to investigate and later arrest Miller for DUI, illegal transportation (open container), no proof of insurance and failure to use a seat belt.
The DUI law is 625 ILCS 5/11-501. In an alcohol-related DUI, a driver may be charged with DUI based upon alcohol-impaired driving or with driving at a blood alcohol level (BAL) above the legal limit.
In all fifty states, the legal limit above which you are assumed to be under the influence of alcohol is .08%. This measures the percent of alcohol in your blood and is by law considered to be too drunk to be driving. At that level, it becomes the defendant’s burden to show he was not under the influence.
In addition, however, if the state is able to prove that someone was driving with a BAL of at least .08, that in and of itself is proof of DUI, regardless of any evidence the driver presents that he or she was not impaired. This is known as a “per se” law.
