At what Blood Alcohol Concentration (BAC) level is a person considered DUI?

A person is considered driving under the influence (DUI) when their Blood Alcohol Concentration (BAC) level reaches .08 or more. This threshold is established in many jurisdictions, including those that fall under the Okinawa Status of Forces Agreement (SOFA), as a standard for determining impairment due to alcohol consumption while operating a vehicle.

The reasoning behind setting the BAC limit at .08 is based on research that indicates this level is significantly associated with increased risks of accidents, impairing judgment, coordination, and reaction times necessary for safe driving. It's important for individuals to understand that operating a vehicle with a BAC of .08 or higher can lead to legal consequences, regardless of their perceived level of intoxication.

Understanding this standard is crucial for maintaining road safety and complying with local laws, especially for military personnel and their dependents in Okinawa, where SOFA regulations apply.
