Penalties & Enforcement

Enforcement for vehicle emissions in San Jose is carried out by a mix of agencies depending on the violation: the City of San José for local code or idling ordinances, the California Air Resources Board (CARB) for state vehicle standards, and the Bureau of Automotive Repair (Smog Check program) for inspection and repair requirements. For regional air quality rules affecting mobile sources, the Bay Area Air Quality Management District may also take enforcement action. [1][2][3]
