California uses the abbreviation DUI, not DWI, to refer to drinking and driving (in contrast, drinking while under the influence of drugs is DUID). You will get arrested for a DUI, and your driver’s license will be suspended, if you are older than 21 and have a BAC of .08 percent or higher.
For the first offense, your license will be suspended for four months. The suspension length is between one and 10 years for the second and subsequent offenses for those over 21. For those under 21, your license will be suspended for a year if your BAC is .01 percent or more, according to the State of California Department of Motor Vehicles.
