What is the legal limit of BAC (Blood Alcohol Concentration) that defines legal intoxication in most states?

In most states across the United States, the legal limit for Blood Alcohol Concentration (BAC) that defines legal intoxication while driving is 0.08%. This standard was established to provide a clear and consistent measurement for law enforcement and the legal system in addressing impaired driving. A BAC of 0.08% indicates that an individual has a level of alcohol in their bloodstream that can significantly affect their cognitive and motor skills, impairing their ability to operate a vehicle safely.

While lower BAC levels can also impair driving abilities, 0.08% has been widely adopted as the threshold for legal intoxication, which is why it is crucial for individuals to be aware of this limit to avoid legal consequences and ensure road safety.
