Aftermarket Alternative Fuel Vehicle (AFV) Conversion Requirements

Conventional original equipment manufacturer passenger vehicles and light-duty trucks may be converted to operate on alternative fuels as a dedicated or bi-fuel AFV. Vehicles altered to operate on propane, natural gas, methane, ethanol, or electricity are classified as aftermarket AFV conversions. All vehicle conversions must meet current applicable U.S. Environmental Protection Agency or California Air Resources Board standards for aftermarket conversions.
