The DUI Law in California
Drunk driving is charged as DUI in California, at a blood alcohol level of 0.08 or more.
Driving in California is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the DMV, separately from the criminal case.
For charging and sentencing, California counts prior offenses within 10 years.

California has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The DMV runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the California Department of Motor Vehicles keeps the driving record the conviction goes on.

- The arrest report: from the agency that made the arrest, under the California Public Records Act.
