could you go to court alone if you are turning 18 before the court date ?
You can go to court, without an attorney and without a parent and represent yourself if you so choose, because you are going to be 18 by the time of the Court date. This would probably be a worse decision than getting drunk and driving into another car. Have you ever heard the old saying: 'The man who represents himself has a fool for a client." ? This would be especially true in your case. From the description of your case, you have not shown either maturity nor respect for the rights or safety of others, let alone the law. You can expect that the Court will most likely treat you very harshly, and as Mr. Middlebrook said- even more so if there was an injury.
In addition, this kind of case is very expensive. The fines, classes and penalties in this situation can easily add up to over $7500 or more, and that does not include what you have to pay an attorney, who will not be cheap.
My suggestion is for you to get online to research DUI attorneys in the Redding area (which it was indicated this originated from) and start finding one right away.
DON'T GO TO COURT WITHOUT AN ATTORNEY OR YOU MAY GO DIRECTLY TO JAIL.
These are significant crimes, the severity of the consequences will depend on the facts of your case. Many lawyers offer free consultations, you should contact a local DUI defense attorney and/or juvenile criminal defense attorney to discuss the facts of your case and the possible/likely outcomes and what can be done to fight the charges.
There are so many variables in this it’s hard to answer. The case will be handled in the juvenile courts. There certainly will be some very stiff punishments and more so if someone was injured. There will a significant license suspension of at least a year. Likely to be charged with multiple misdemeanors and maybe felonies. It’s imperative to seek the advice of counsel in this scenario.
