You may ask the court for a new court date within 20 days of your original date. This is done by filling out a form in the Clerk of Court's office. You state your original court date, your offense, and why you missed that date. If it is a good reason, a judge will grant a new date and you will be notified by mail.

Once your case is disposed of, any arrest warrants will be struck.
