Chapter 45 - Other Required Equipment
4531 - Emission control systems.

     § 4531.  Emission control systems.
        (a)  Compliance with established maximum levels.--No vehicle
     manufactured in compliance with the requirements of the Clean
     Air Act (77 Stat. 392, 42 U.S.C. § 1857), or any amendments or
     supplements thereto, shall have emissions exceeding the maximum
     permissible levels prescribed by law.
        (b)  Limitation on alteration of system.--No person shall
     disable, change or alter the emission control system of a
     vehicle. Original emission control components or replacements in
     kind shall be present and functioning on all vehicles. A subject
     vehicle may be equipped with any added components which are
     designed to improve emissions. It is unlawful for a subject
     vehicle that is not in compliance with the preceding
     requirements to be operated under its own power until a
     reinspection at an official emission inspection station
     establishes its full compliance, provided that it shall be
     lawful for the vehicle to be operated under its own power by the
     vehicle owner while en route to the official emission inspection
     station for a reinspection.
        (c)  Limitation on sale and operation of vehicles with
     altered systems.--No person shall knowingly sell or operate a
     vehicle whose emission control system has been disabled, changed
     or altered from its original design specifications, except for
     in-kind replacement of system components and added components
     which are designed to improve emissions.
