2. May an officer take my home state license?
Not usually. A driver license is commonly known to be the property of the state which issued it. Although Sonoma County police have the duty to confiscate a California driver license under the "stop and snatch" law (CVC 13382) following an alcohol-related DUI arrest, this authority is not extended to non-California licenses.
Typically, licenses which are confiscated by Sonoma County law enforcement are forwarded to the DMV and destroyed within days of arrest. If you held a driver license issued by a state other than California and it was confiscated, contact a Santa Rosa DUI attorney, such as Jake, immediately to try to secure the return of your home state license before it is destroyed. Consult with a Sonoma County DUI attorney about your individual case.
