I strongly suggest that you discuss the means of getting your license back with your DUI attorney. If you did not have an attorney, see one now.
The above is not intended as legal advice. The response does not constitute the creation of an attorney client relationship as this forum does not provide for a confidential communication.
As my colleague said, you need to talk to your trial attorney or if you don't have one, at the very least consult with an attorney directly about your question. I don't practice in California, but, I can tell you that in most states the license suspension by DMV is a separate proceeding from the criminal proceeding so that if you did not contest the DMV's suspension of your license and later you win the criminal trial, the license suspension remains in effect.
It's interesting that DMV will reopen your case. That is the only way you can get your license back. It doesn't matter the result in court. The punishment for a refusal at the DMV level is a 1 year loss of license no matter the outcome of the court case. If this were not hte case many more people would refuse to give a chemical sample.
You need to file a DS702 form with the DMV. This form is only available at your local driver’s safety office and is not available online. You will want to take it to the DA to sign as to why your case was dismissed (in this case you were found not guilty by jury) (understand that is not the same thing as innocent). Once this form is submitted to the DMV you should be granted a new hearing. Expect to lose the next hearing (this is how the DMV works). After you lose you will need to file a writ. This means that your case will be heard by a judge and if successful you will get the license back. This is not a do it yourself project hire an attorney that is familiar with this process.
Check the Court records. As the other attorneys mentioned, if it was a finding of "not guilty"/hung jury, you may need to request to reopen the hearing. If, however, you received an Acquittal (factual finding of innocence) than it may be possible to submit that documentation to Driver Safety headquarters and ask for reinstatement of your license.
Definitely do not try to do this yourself, as they may lead to more problems. Look for a DUI attorney local to you and discuss the case with them in detail. After that, they should be able to let you know what the appropriate course of action should be.
