What is the legal limit for Blood Alcohol Concentration (BAC)?

The legal limit for Blood Alcohol Concentration (BAC) is set at 0.08%. This threshold is the standard used across the United States to determine whether a driver is impaired by alcohol while operating a vehicle. When a driver's BAC reaches or exceeds this level, they are considered legally intoxicated and subject to penalties, including fines, license suspension, and possible imprisonment.

This limit is based on extensive research showing that impairment significantly increases at or above this BAC level, impacting a person's ability to operate a vehicle safely. It is crucial for drivers to be aware of this limit in order to make responsible decisions regarding alcohol consumption and driving.
