Does my suspension get reduced if the DUI charge is dropped to a wet reckless?

It depends on several factors.

The DMV makes their own independent decision. They are not controlled by the court resolution. The only hope was to either win your hearing at DMV or get the case dismissed.

No, you still have a four month suspension; you avoid an additional six month suspension. You can apply for a restricted license after one month.

The court reduction to a wet doesn't do anything for you at the DMV. If you lose the DMV hearing (which it sounds like you did), they will suspend your license regardless of what happens in court. And, you need to do the AB-541 program, or else the DMV will never re-issue your license. Remember, the court case and the DMV case are completely separate!

Not automatically. You need to submit a DS 702 to the DMV Mandatory Actions Unit in Sacramento showing that the DUI charges were dismissed. This will trigger a second DMV hearing where you can try to beat them again. If you obtained a plea pursuant to Helmandollar v DMV, 7 Cal.App.4th 52, you need to submit the DS 702 showing that there was a not guilty on the .08 or above charge. A Helmandollar plea involves negotiating a plea to wet reckless or something else and rather than dismissing the .08 or above count, there is a mini-bench trial wherein the DA doesn't present any evidence and after they rest, the defense makes a PC 1118.1 motion and the defendant is acquitted of the charges. You then take the not guilty finding to the DMV and the suspension is set aside. 73 Be aware that the DMV sometimes requires completion of the AB 541 class to get your license back (that is on the waiver forms in Los Angeles County).

The suspension is from the DMV not the courts. It is often the case that the DMV imposes the suspension and the court reduces the charge but you have to serve the full suspension anyway. This is because the DMV and the courts move separately. You should have asked for a hearing on the suspension from the DMV. That way there was at least a chance you could convince the hearing officer not to suspend your license. Now you are stuck with the four month suspension (BTW, there was never a "30 day" suspension, just 30 days in which you could not even get a restricted license). Once you have enrolled in the wet reckless classes, bring the minute order from the court and proof of enrollment to the DMV and they should give you restricted license.

Does my suspension get reduced?? No. Nothing is automatic. DMV has told you what their position is. If you want to contest their decision, you will have to file an appeal, and/or go to court by filing for a Writ.
