In Nevada, what happens to vehicles that are considered gross polluters?

When a vehicle is classified as a gross polluter in Nevada, it indicates that the vehicle emits pollutants beyond acceptable limits. Therefore, it is essential for such vehicles to undergo repairs to rectify the issues causing excessive emissions. This requirement ensures that vehicles comply with state and federal emissions standards, which are in place to protect air quality and reduce pollution levels. By mandating repairs, Nevada aims to improve the performance of these vehicles and promote environmental health.

The other options do not align with the state's regulatory framework. For example, exempting gross polluters from emissions testing would undermine the purpose of emissions regulations, while allowing them to operate without restrictions could lead to increased air pollution. Similarly, passing emissions testing after a fee contradicts the principle of ensuring that vehicles meet environmental standards, as merely paying a fee does not address the underlying emissions issues.
