What is the legal blood alcohol concentration (BAC) limit for drivers in California?

In California, the legal blood alcohol concentration (BAC) limit for drivers is established at 0.08%. This threshold is critical for determining whether a driver is considered legally impaired and can be charged with driving under the influence (DUI). The BAC limit reflects the state’s efforts to ensure road safety and reduce accidents associated with alcohol consumption.

At a BAC of 0.08%, an individual's ability to operate a vehicle is significantly impaired, affecting coordination, judgment, and reaction times. Identifying this specific percentage as the legal limit provides a clear standard for both law enforcement and drivers, helping to promote responsible drinking and driving behaviors. In various situations, there are different thresholds for specific groups, such as drivers under 21 or commercial drivers, but for the general population, 0.08% is the benchmark established by California law.
