20.14 Exhaust Emission System. The owner or operator of any new motor vehicle or new motor vehicle engine beginning with the model year 1968 equipped with an exhaust emission system shall maintain the exhaust emission system in good operable condition and shall use it at all times that the motor vehicle or motor vehicle engine is operated. The owner or oper-
ator of the motor vehicle or motor vehicle engine shall not remove or intentionally make inoperable within the state of Texas the exhaust emission system or any part thereof, except where the purpose of removal of the exhaust emission system or part thereof is to install another exhaust emission system or part thereof, which is intended to be equally effective in reducing atmospheric emissions from the vehicle or engine.
The exhaust emission system was installed by manufacturers of motor vehicles beginning with model year 1968. The inspection of the exhaust emission system will apply only to those vehicles that are equipped with such a system. The following exhaust emission systems will be inspected if installed as original equipment by the manufacturer: thermostatic air cleaner, exhaust gas recirculation system, positive crankcase ventilation system, air injection system, evaporative emission system, and/or catalytic converter.
If installed as original equipment by the manufacturer, the catalytic converter will be considered a part of the exhaust emission system on all 1984 and later model vehicles. It will be inspected as a part of the exhaust system on prior to 1984 model vehicles.
NOTE: The inspection of the exhaust emission system shall not apply to motor vehicles altered and modified to use only a fuel other than gasoline.
NOTE: Vehicles using liquefied petroleum gas as fuel or a combination of liquefied petroleum gas and any other fuel must bear a liquefied gas tax decal on the windshield lower right-hand corner showing this vehicle uses liquefied petroleum gas, before a safety inspection certificate can be issued.
NOTE: A motor vehicle that uses liquefied petroleum gas that is operated by a public school district or county in this state is not required to have a liquefied gas tax decal or special use liquefied gas tax decal.
