When you have been arrested for suspicion of driving under the influence of alcohol or drugs, you are not yet convicted. The prosecutor on your case has to prove that you are guilty beyond a reasonable doubt before you can be convicted and sentenced for your case.
Your first court appearance is called an Arraignment. At the arraignment the Judge will inform you of your Constitutional rights and you will be given a plea bargain. A plea bargain is an offer a prosecutor will make to a defendant. It usually involves a lesser charge or penalty, and the offer is only on the table for the arraignment. If you plead guilty and accept the offer, your case will be concluded and you will not have a chance to go to trial.
When you decide to plead guilty, you will be given a Tahl waiver to initial and sign. The Tahl waiver is a very important document and it is highly recommended that you thoroughly review and understand the document before you sign it. If you have a Los Angeles DUI lawyer, it is extremely important that you take the time to sit and review the document with your attorney before you sign and initial it.
