Yes. You can present your own evidence at a DMV hearing. Once you determine the best defense to raise at the hearing, you should then gather and organize any evidence that supports that defense. A few common forms of evidence include: witness statements, medical records, photos, and surveillance video. As to witness statements, you can either submit written witness statements into evidence, or you can have a witness attend the hearing process and present live testimony. Further, you can issue a subpoena to help ensure that a witness will attend a hearing to testify.
