What is considered a 'gross polluter' in vehicle emissions?

A 'gross polluter' refers to a vehicle that emits excessively high levels of pollutants, significantly surpassing the limits set by environmental regulations. This classification is designed to identify vehicles that contribute disproportionately to air quality degradation due to their emissions. Such vehicles may be the result of poor maintenance, using outdated technology, or having mechanical issues that lead to increased emissions.

While vehicles that meet emissions standards are compliant and those that emit minimal pollutants are environmentally friendly, gross polluters represent a serious concern for public health and environmental quality. Identifying and addressing vehicles classified as gross polluters is a key aspect of emissions control programs to help improve air quality and reduce health risks associated with air pollution.
