What is a possible consequence of failing to comply with emissions regulations?

Failing to comply with emissions regulations can lead to fines and penalties imposed by regulatory authorities. These regulations are in place to limit the amount of pollutants that vehicles can emit into the environment, and non-compliance typically triggers legal and financial repercussions. Governments and environmental agencies enforce these regulations to protect public health and the environment, and they generally have established a structured process for assessing and penalizing violations. Penalties can vary in severity but may include financial fines, mandated repairs, and even restrictions on vehicle operation until compliance is achieved.

In contrast, the other implications suggested, such as having no impact on vehicle operation, increased repair costs, or improved fuel performance, do not align with the consequences of non-compliance. While failing to meet emissions standards may lead to decreased vehicle performance over time, the direct consequence is the financial and legal repercussions that can arise from regulatory inspections and enforcement actions.
