For a specially constructed SPCN vehicle, which vehicle make should be entered into the Emission Inspection System (EIS)?

• A. The original make of the vehicle
• B. The SPCN designation
• C. The manufacturer of the aftermarket converter
• D. Unknown

Answer: (A)

For an SPCN (specially constructed) vehicle, the Emission Inspection System uses the original vehicle make to determine the proper test parameters and to record the inspection history. The system relies on the original manufacturer’s make to apply the correct standards, even if the vehicle has been modified or converted. The SPCN designation itself is administrative and does not change the make that the EIS uses. The aftermarket converter’s manufacturer is a component detail and not used to define the vehicle’s make, and leaving the make as unknown isn’t the standard practice. So, you should enter the original vehicle’s make. For example, if the vehicle started as a Ford, you enter Ford.
