(a)If the department receives an application for registration of a specially constructed passenger vehicle or pickup truck after it has registered 500 specially constructed vehicles during that calendar year pursuant to Section 44017.4 of the Health and Safety Code, and the vehicle has not been previously registered, the vehicle shall be assigned the same model-year as the calendar year in which the application is submitted, for purposes of determining emissions inspection requirements for the vehicle.
(b)If the department receives an application for registration of a specially constructed passenger vehicle or pickup truck that has been previously registered after it has registered 500 specially constructed vehicles during that calendar year pursuant to Section 44017.4 of the Health and Safety Code, and the application requests a model-year determination different from the model-year assigned in the previous registration, the application for registration shall be denied and the vehicle owner is subject to the emission control and inspection requirements applicable to the model-year assigned in the previous registration. For a vehicle that participated in the amnesty program pursuant to Section 9565, the model-year of the previous registration shall be the calendar year of the year in which the vehicle owner applied for amnesty. However, a denial of an application for registration issued pursuant to this subdivision does not preclude the vehicle owner from applying for a different model-year determination and application for registration under Section 44017.4 of the Health and Safety Code in a subsequent calendar year.
