What is the legal blood alcohol concentration (BAC) limit for intoxication in Illinois?

The legal blood alcohol concentration (BAC) limit for intoxication in Illinois is set at .08. This means that individuals operating a motor vehicle with a BAC at or above this level are considered legally intoxicated and can be charged with driving under the influence (DUI).

The .08 limit is consistent with many other states, reflecting a nationwide standard aimed at reducing alcohol-related accidents and enhancing road safety. This legal standard is based on research indicating that at a BAC of .08, an individual's ability to drive safely is significantly impaired.

Choosing a lower limit, such as .05, would not accurately represent the legal threshold established in Illinois for intoxication while driving. Options .10 and .12 exceed the established limit and would also lead to the assumption of legal intoxication, which is incorrect. Understanding this regulation is crucial for bartenders, as it impacts responsible alcohol service and awareness of the law regarding patrons who may be at risk of reaching or exceeding this limit.
