The DUI Law in California
In California the offense is DUI, and the limit is 0.08.
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.
