Welcome to ADEQ Vehicle Emissions Inspection Program

To improve air quality and reduce vehicle emissions, 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 to increase the effectiveness of emissions testing and shorten the time customers spend in the testing process. The results are cleaner air, faster testing procedures and better customer service.
