Are attorneys able and willing to give me an estimate of success rate for DUI case?

An attorney cannot ethically guarantee a result which is out of his complete control. The outcome does not only depend on the facts, but also the judge, prosecutor, and the jury. A person can only safely predict the past – not the future. You may never be certain what the outcome will be if you hire an attorney, but we all know what will happen if you don’t. That being said, you should always hire the best expert you can afford.
