In the state of California it is illegal to drive a vehicle when a person’s blood alcohol content is 0.08% or greater, 0.04% for commercial vehicle drivers, and 0.01% for those under 21 years of age. The type of alcohol (liquor, beer/wine, mixed), number of drinks consumed, and other factors such as medications, fatigue, food consumption, gender and weight can affect someone’s blood alcohol content.
Drunk driving that causes injury is often called a “wobbler” charge in California. This means that the charge may be prosecuted as a misdemeanor or felony at the prosecutor’s discretion. Prosecutors consider the details of the DUI case and the defendant’s criminal history.
