Vermont § 567 - Motor vehicle pollution

§ 567. Motor vehicle pollution

• (a) The Secretary in conjunction with the Department of Motor Vehicles may provide rules
  for the control of emissions from motor vehicles. Such rules may prescribe requirements
  for the installation and use of equipment designed to reduce or eliminate emissions
  and for the proper maintenance of the equipment and the vehicles. Rules pursuant
  to this section shall be consistent with provisions of federal law, if any, relating
  to control of emissions from the vehicles concerned and shall not require, as a condition
  precedent to the initial sale of a vehicle or vehicular equipment, the inspection,
  certification, or other approval of any feature or equipment designed for the control
  of emissions from motor vehicles, if the feature or equipment has been certified,
  approved, or otherwise authorized pursuant to federal law. (b) Except as permitted or authorized by law, no person shall fail to maintain in good
  working order or remove, dismantle, or otherwise cause to be inoperative any equipment
  or feature constituting an operational element of the air pollution control system
  or mechanism of a motor vehicle and required by rules pursuant to this chapter to
  be maintained in or on the vehicle. Any failure to maintain in good working order
  or removal, dismantling, or causing of inoperability shall subject the owner or operator
  to suspension or cancellation of the registration for the vehicle by the Department
  of Motor Vehicles. The vehicle shall not thereafter be eligible for registration until
  all parts and equipment constituting operational elements of the motor vehicle have
  been restored, replaced, or repaired and are in good working order. (c) The Secretary shall consult with the Department of Motor Vehicles and furnish it with
  technical information, including testing techniques, standards, and instructions for
  emission control features and equipment. (d) When rules have been issued requiring the maintenance of features or equipment in
  or on motor vehicles for the purpose of controlling emissions therefrom, no motor
  vehicle shall be issued an inspection sticker unless all the required features or
  equipment have been inspected in accordance with the standards, testing techniques,
  and instructions furnished pursuant to subsection (b) hereof and has been found to
  meet those standards. (e) The remedies and penalties provided here apply to violations of this section and provisions
  of section 568 of this title shall not apply. (f) As used in this section, “motor vehicle” shall have the same meaning as defined in
  23 V.S.A. § 4. (Added 1967, No. 310 (Adj. Sess.), § 16; amended 1971, No. 212 (Adj. Sess.), § 3.)
