Why Emissions Testing Is Essential

The quality of the air we breathe is more important than ever. All Arizonans deserve the cleanest possible air today, for our future -- especially those with compromised health. We all can make a positive difference by the choices we make and actions we take everyday. Vehicle emissions contribute to increased levels of air pollution like man-made ozone and particulate matter (smoke and dust). And, for the millions of Arizonans who choose to own and operate motor vehicles, each plays an important role in maintaining and improving Arizona’s air quality by simply testing vehicle emissions to ensure they meet health-based standards.
