Vehicle Emissions Inspection Program Hotline:
Increasing vehicle use in metropolitan Phoenix and Tucson contributes to air pollution that endangers public health. To improve air quality and reduce vehicle emissions in these areas, ADEQ administers a mandatory vehicle emissions testing and repair program known as Vehicle Emissions Inspection Program (VEIP).
VEIP emphasizes the importance of maintaining vehicle performance to lower emissions and extend the life of one of your most valuable assets - your car. VEIP uses new testing technology and customer service measures that increase the effectiveness of emissions testing and shortens the time customers spend in the testing process. The results are cleaner air, faster testing procedures and better customer service.
Reducing fees, helping customers
In 2014, ADEQ lowered vehicle emissions inspection fees by 25% for millions of Maricopa County motorists - from $27.75 to $20. The agency also now replaces faulty gas caps for free when vehicles in Maricopa and Pima counties fail the gas cap test during the emissions inspection. This has resulted in more environmental good because, in cases where the gas cap is the only reason for a failed inspection, motorists no longer need to drive off, purchase a new cap and return to the station for a retest. An estimated 75,000 customers a year will benefit from the added convenience, while millions more enjoy the benefits of cleaner skies and healthier air quality.
