• A. A Grey Market Vehicle is a vehicle originally manufactured for sale inside the U.S.
• B. A Grey Market Vehicle is a vehicle designed for off-road use.
• C. A Grey Market Vehicle is a vehicle powered by alternative fuels.
• D. A Grey Market Vehicle is a vehicle originally manufactured for sale outside of the U.S.

Answer: (D)

In the Smog Check Program, a Grey Market Vehicle is one that was originally manufactured for sale outside of the United States. This matters because those cars were not designed to meet U.S. (and California) emission standards, so they often lack the required emissions equipment or calibration. As a result, they may need modifications or a special exemption to pass smog certification, or in some cases may not be eligible for standard certification at all. The other descriptions describe off-road use, alternative fuels, or U.S.-market origins, which do not define a grey market vehicle.
