A. An AFV is any dedicated, dual-fuel, or flexible-fuel vehicle designed to operate on at least one alternative fuel. A dedicated AFV is designed to operate only on an alternative fuel(s). A dual-fuel (sometimes called bi-fuel) AFV is designed to operate on an alternative fuel or on a conventional fuel (gasoline or diesel). For example, a dual-fuel natural gas vehicle stores compressed natural gas in one fuel tank and gasoline in another, and the driver can choose the fuel used by the vehicle at any given time. In contrast, a flexible-fuel vehicle (FFV)—which can operate on gasoline, E85 (85% ethanol, 15% gasoline), or a mixture of both—stores E85 and gasoline mixed together in a single fuel tank.
