Have someone drive you to court because you might not be able to drive home. You have the absolute right to appeal any criminal conviction within thirty days. You will have to pay for your trial transcript for your appeal. Furthermore, if you are sentenced to a jail term, you might or might not be entitled to an appeal bond, which would allow you to remain free during the appeal process. Any appeal bond will have to be approved by the Clerk of the Court.
Many clerks require cash bonds only.
Some allow you to use a commercial bondsman. An appeal bond postpones your punishment. However, it will not postpone any driver's license suspension.
