What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Illinois?

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Illinois is 0.08%. This means that a driver with a BAC at or above this level is considered legally impaired and can be charged with driving under the influence (DUI). This standard is consistent across many states in the U.S., aimed at ensuring road safety by reducing alcohol-related accidents and fatalities. Maintaining this limit is vital for responsible driving practices, as even small amounts of alcohol can impair judgment and reaction times, increasing the risk of accidents.

Other figures, such as 0.05%, 0.10%, and 0.02%, do not reflect the legal limit for drivers over 21. While lower levels might apply to certain specific cases, such as commercial drivers or underage drinkers, the established standard for general drivers 21 and older is firmly set at 0.08%.
