(ii)  The operator of the motor vehicle who is age eighteen (18) years or older if any occupant under eighteen (18) years of age fails to wear a safety restraint as required in this section. For purposes of this subparagraph, it shall be deemed a single violation regardless of the number of occupants not properly restrained.
(b)  A person issued a citation pursuant to this subsection shall be subject to a fine of ten dollars ($10.00). A conviction under this subsection shall not result in violation point counts as prescribed in section 49-326, Idaho Code, nor shall such a conviction be deemed to be a moving traffic violation for the purpose of establishing rates of motor vehicle insurance charged by a casualty insurer.
(4)  A citation may be issued to the operator of the motor vehicle if the operator is under eighteen (18) years of age and the operator or any other occupant who is under eighteen (18) years of age fails to wear a safety restraint as required in this section.

(5)  Enforcement of this section by law enforcement officers may be accomplished only as a secondary action when the operator of the motor vehicle has been detained for a suspected violation of another law.
(6)  The department shall initiate and conduct an educational program, to the extent sufficient private donations or federal funds for this specific purpose are available to the department, to encourage compliance with the provisions of this section and to publicize the effectiveness of use of safety restraints and other restraint devices in reducing risk of harm to occupants of motor vehicles.
(7)  The department shall evaluate the effectiveness of the provisions of this section and shall include a report of its findings in its annual evaluation report on the Idaho highway safety plan which it submits to the national highway traffic safety administration and federal highway administration pursuant to 23 U.S.C. section 402.
