Vehicle Emissions Inspection Program Hotline: (877) 692-9227

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 heavily traveled 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 shorten the time customers spend in the emissions process. The results are cleaner air, faster testing procedures and better customer service.

The Arizona Motor Vehicle Division and Service Arizona controls registration, title questions, name/address changes and notification of “emissions test required.”. For questions or more information, please contact:
