At what blood alcohol concentration is a person 21 years of age or older considered "under the influence"?

A blood alcohol concentration (BAC) of 0.08 grams per deciliter is the legal limit for individuals who are 21 years of age or older in most states, including Georgia. When a person's BAC reaches this level, they are deemed to have impaired judgment, coordination, and reaction times, which are critical for safe driving. Consequently, individuals at or above this limit can be charged with driving under the influence (DUI).

This standard is established to protect both the driver and other road users by ensuring that those with a BAC at or above this threshold are held accountable for their impaired state. Understanding this legal limit is vital for anyone planning to consume alcohol and then operate a motor vehicle, as it highlights the legal implications and the importance of responsible drinking.
