What is the blood alcohol concentration (BAC) limit for adults charged with DUI under California law?

In California, the legal blood alcohol concentration (BAC) limit for adults charged with driving under the influence (DUI) is set at 0.08%. This means that if a driver's BAC is at or above this level, they can be charged with DUI. This regulation is part of a broader effort to ensure road safety and reduce the incidence of alcohol-related accidents.

Additionally, individuals driving commercial vehicles have a lower limit of 0.04%, while drivers under the age of 21 are prohibited from having any measurable alcohol in their system, reflecting California’s zero-tolerance policy regarding underage drinking and driving. The 0.08% threshold is widely recognized within law enforcement and is reinforced through various training programs for peace officers, emphasizing the importance of understanding and enforcing these legal standards for public safety.
