California's Low-Emission Vehicle regulations provide for reduced emission vehicles to be available to consumers.<br />

Vehicles meeting these standards have even lower emissions than the basic Tier 1 standards for all new vehicles<br />

sold in California. Currently, there is a wide array of TLEVs and LEVs, and a few ULEVs, SULEVs and ZEVs on<br />

the market. For a listing of the available low emission vehicles, see the California Air Resources Board web site<br />
