California Administrative Per Se:

When an individual is stopped or arrested the officer takes your license and issues a temporary 30-day driving permit. This license action is separate from any criminal charges you face related to your DUI arrest. You can continue to drive in California and avoid suspension after a DUI arrest if you install an ignition interlock device in your vehicle.

Criminal Consequences for California DUI:

If you are convicted of a DUI offense, penalties apply, based on the number of times you have been convicted of DUI, if there was a crash or injury while you were driving under the influence and how much time has elapsed between the convictions.
