According to most state laws, what BAC level is considered illegal for driving?

The legal Blood Alcohol Concentration (BAC) limit for driving, as established by most state laws, is 0.08 percent. This standard has been widely adopted across the United States and serves as a benchmark to identify impaired driving. At a BAC of 0.08, individuals may experience significant reductions in their ability to operate a vehicle safely, including impaired judgment, reduced coordination, and slower reaction times. This level is specifically chosen to err on the side of safety, promoting responsible drinking and driving practices.

Other BAC levels listed, such as 0.05, 0.10, and 0.12, may have varying implications but do not represent the universally accepted threshold for legal impairment while driving in the majority of states. For instance, some states have a lower limit of 0.05 for specific groups, like commercial drivers or underage individuals, but 0.08 is the standard limit for the general driving population. Understanding the significance of this limit is crucial for promoting public safety and adherence to driving regulations.
