The officer will give you an Order of Suspension/ Revocation. If you have a valid California driver license, the officer will take your driver license and send it to the DMV (to be destroyed). The Order of Suspension/Revocation includes a temporary driver license valid for 30 days from the issue date (usually the date of your arrest).
At the end of the 30 days, the suspension/ revocation action goes into effect. If the officer does not serve you with an Order of Suspension/ Revocation, the DMV will mail you one. The temporary driver license does not allow you to drive if there is another DMV or court-imposed driver license action in effect.
The Admin Per Se (APS) suspension or revocation is independent of any jail, fine, or other criminal penalty imposed in court if you were convicted of a DUI offense.
