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.
