Low-Emission Vehicle (LEV II) Program
Following a November 5, 1998, hearing, the Air Resources Board (CARB) amended California's Low-Emission Vehicle (LEV) regulations. The new amendments, known as LEV II, included three major interrelated elements designed to reduce criteria pollutant exhaust emissions: 1) expanding the light-duty truck category up to 8,500 lbs., GVW so that most sport utility vehicles, mini-vans and pick-up trucks were subject to the same low-emission vehicle standards as passenger cars, 2) strengthening the oxides of nitrogen (NOx) standard for passenger cars and light-duty trucks, and changing other emission standards, and 3) establishing more stringent 2004 through 2010 model year phase-in requirements for passenger cars, light-duty trucks and medium-duty vehicles. The LEV II standards flat-lined at model year 2010 levels through model year 2014.
