The commissioner may appoint state employees or other persons to take applications, issue licenses, permits, and tags, and collect fees. The commissioner is not liable for defalcation or failure to account for the fees collected by any person so appointed, but the commissioner shall require a bond in an adequate sum, conditioned upon faithfully accounting for all money collected. However, the commissioner may waive the bond requirements of an instrumentality of the United States or its agents and employees when the instrumentality or its agents or employees sell licenses, permits, or tags primarily to persons in the armed forces. Each person, upon appointment by the commissioner, may administer oaths on applications for licenses, permits, and tags.
