If I am found guilty in district court can I appeal it to superior court

You have 10 days from the date of conviction to file an appeal.  Once the case has been appealed to Superior court, you will have to deal with the DA who is handling it in Superior Court to see what deals they will offer you if you get your driver's license back.   I would suggest you retain an attorney while the case is still in District Court, as he or she may be able to secure additional continuances, and to resolve your case favorably without the added time and expense of dealing with the case in Superior court.
