Whether you live in Arizona or you are just here for an international job, you deserve to breathe clean air at all times. Without strategies such as mandatory vehicle emission testing, the air could be far much polluted and a major threat to human health.
The only way you can support the government in this is by visiting the emissions testing location near you when your car is due for inspection. In the future, expect emissions testing locations and services to improve since ADEQ is continually refining all the processes revolving around the inspection process.
