I have a hearing to get my car back bc of aiding and abetting a dui... whats the chances i get it back?

More facts about the case itself, the relationship to the principal, and your background would be required to give a thorough answer.

I see no one has answered your question, please consider calling a local DUI lawyer. Most will give a free consultation.

First, you should not attempt to handle this hearing yourself. Your attorney will have to prove to the court either you did not know the DWI driver was driving, or did not have your permission to drive. Unfortunately, since you received a PJC, you first had to plead guilty to the aiding and abetting. The judge may look at that as an admission on your part that you gave the driver permission to drive your vehicle. Consult an attorney immediately.

It would be hard to give you percentages on this, and they really wouldn't mean much anyways because your case is going to be so dependent on the facts. Because you stand the chance of losing your car, I would consult with an attorney on this matter.
