Vehicle inspections to assess the level of pollutants released into the atmosphere are mandated in specific geographic regions to ensure compliance with environmental regulations. This process, required for vehicle registration renewal, involves evaluating exhaust fumes against established benchmarks. Tempe, Arizona, is one such location where vehicles must undergo this type of assessment.
The primary rationale behind this requirement is the improvement of air quality and the mitigation of negative health effects associated with pollution. By identifying and addressing vehicles exceeding permissible emission levels, these programs contribute to a cleaner, healthier environment for residents. Historically, such programs have played a significant role in reducing smog and other forms of air pollution in urban areas.
