Alternative Fuel Vehicle (AFV) Emissions Inspection Exemption

AFVs powered exclusively by electricity, natural gas, liquefied petroleum gas, and propane are exempt from state emissions control inspections. Plug-in hybrid electric vehicles that obtain a U.S. Environmental Protection Agency fuel economy rating of at least 50 miles per gallon during city driving are also exempt from these inspections.
