What BAC level is generally sufficient for convictions related to DUI or DWI?

The blood alcohol concentration (BAC) level of .08 to .10 is widely recognized as the threshold at which individuals can be convicted of driving under the influence (DUI) or driving while intoxicated (DWI) in many jurisdictions. This standard is based on extensive research that has shown impairment in motor skills, judgment, and reaction times at this level of alcohol consumption.

Law enforcement agencies often use this BAC range to guide breathalyzer tests and field sobriety tests when assessing a driver's fitness to operate a vehicle. The .08 BAC limit is also a legal standard in the United States for drivers over the age of 21, as established by federal and state regulations.

Other BAC ranges, such as .02 to .06, might indicate some level of impairment but typically do not reach the threshold for legal conviction. Driving with a BAC below .08 may result in other penalties or citations depending on the specific laws of a state, but it is the .08 and above range that is most commonly associated with DUI/DWI convictions.
