RULE 6.150. WITNESSES

(a) Procedure. The procedure prescribed by law in civil and
criminal cases concerning the attendance and testimony of
witnesses, the administration of oaths and affirmations, and
proceedings to enforce the remedies and protect the rights of the
parties shall govern traffic cases as far as they are applicable unless
provided otherwise by these rules or by the law. Payment of witness
fees and costs of serving witnesses in civil traffic cases shall be
made in the same manner as in a criminal traffic case.

may offer evidence of other witnesses through use of one or more

affidavits shall not be admissible for the purpose of establishing
character or reputation.
