Why might a vehicle owner face additional penalties after repeated emissions test failures?

The rationale behind the possibility of additional penalties for a vehicle owner who has repeated emissions test failures centers on promoting compliance and ensuring that vehicles meet environmental standards. When owners fail emissions tests multiple times, it reflects a persistent issue that could contribute significantly to air pollution.

The emphasis on discouraging non-compliance stems from the need to maintain air quality and adhere to environmental regulations. These penalties serve as a deterrent, encouraging vehicle owners to take necessary steps to repair their vehicles in order to reduce harmful emissions. By imposing additional penalties, regulatory agencies aim to enforce stricter adherence to emissions standards, ultimately working toward cleaner air and public health objectives.

The other options, while they may touch upon related aspects, do not provide the core reasoning behind the imposition of penalties aimed specifically at promoting compliance with emissions standards.
