     "Exhaust emission control system" means a system, device, or engine modification designed and installed in such a manner as to reduce or prevent the emission to the atmosphere of air pollutant gases, vapors, and particulate matter released from the motor vehicle engine through the exhaust manifold and tailpipe.
     "Motor vehicle" means a self-propelled, wheeled vehicle designed for normal use on public streets and highways.
     "Motor vehicle pollution control device" means any or all of the devices or systems referred to in this Subchapter and designed to control or prevent air pollution emissions from motor vehicles.
     "New vehicle" means a motor vehicle which is in the possession of persons in the channels of commerce in such a manner that the vehicle is not subject to registrations with the Oklahoma State Tax Commission by the ultimate purchaser.
     "Positive crankcase ventilator" means a system or device designed and installed in such a manner as to prevent or reduce the release or emission to the outside atmosphere of gases and/or  vapors produced or otherwise present in the crankcase of the engine of a motor vehicle.

252:100-15-3.  Scope

     This Subchapter shall apply to all motor vehicles, registered or subject to registration with the Oklahoma State Tax Commission, in which, as new vehicles, motor vehicle pollution control devices have been installed by virtue of federal laws and regulations, in effect now and hereafter, requiring such devices to be installed.  However, nothing in this Subchapter shall supersede or otherwise modify such federal laws and rules, nor shall anything in this Subchapter be construed to require the installation of motor vehicle pollution control devices on motor vehicles not referred to by such federal laws and rules.

252:100-15-5.  Maintenance, repair, or testing

     For the purpose of routine maintenance, repair, or testing of the motor vehicle, its components, or the motor vehicle pollution control devices, the motor vehicle or its engine may not be operated on public streets or highways with the motor vehicle pollution control devices removed or otherwise rendered inoperable.
