Which of the following is NOT a goal of vehicle emissions regulations?

Reducing transportation costs is not a primary goal of vehicle emissions regulations. These regulations are designed primarily to address environmental and public health concerns. The main objectives include protecting air quality, improving public health, and mitigating climate change by limiting the release of harmful substances into the atmosphere.

When emissions standards are set, they aim to reduce pollutants that can contribute to respiratory illnesses and environmental damage, ensuring a healthier population and environment. Although achieving cleaner vehicle emissions may indirectly lead to some cost savings over time—such as reduced healthcare costs associated with pollution-related illnesses—this is not the direct focus of emissions regulations. The emphasis is on safeguarding health and the environment rather than on economic factors such as transportation costs.
