What is considered legally intoxicated in terms of BAC?

In Illinois, a Blood Alcohol Concentration (BAC) of 0.08 or above is considered legally intoxicated for drivers aged 21 and over. This standard is established to promote safety on the roads and holds individuals accountable if they operate a vehicle under the influence of alcohol. Operating a vehicle with a BAC at this level indicates that the driver may be impaired in terms of judgment, coordination, and reaction times, which increases the risk of accidents.

While lower BAC levels can also affect driving ability, 0.08 is the threshold set by law for determining intoxication in adults. Different states may have varying definitions, and some may establish different limits for commercial drivers or underage drinkers. However, in the context of Illinois law for general drivers, 0.08 is the pivotal figure.
