Costa Mesa Star Certified Smog Check Center

Expertec Automotive holds state certification as a Smog center for Testing and Repair and is authorized by California to conduct repairs through the CAP repair assistance program.

The California STAR Certified Smog Check Program aims to curtail vehicle-induced air pollution by ensuring compliance with the state’s emission standards.

A STAR Certified station adheres to rigorous performance criteria set by the California Bureau of Automotive Repair (BAR). These stations are equipped with advanced emissions testing technology, and their technicians receive specialized training to accurately assess vehicle emissions.

The STAR program’s objective is to pinpoint high-emission vehicles, facilitate their repair or retirement, and mitigate air pollution. It plays a crucial role in upholding California’s air quality standards and safeguarding public health.

The CAP Repair Assistance Program

The Consumer Assistance Program (CAP) Repair Assistance Program, a California initiative, aids low-income vehicle owners in repairing or retiring their vehicles if they fail smog checks.

Administered by the California Bureau of Automotive Repair, CAP requires vehicle owners to meet income eligibility criteria for assistance.

Assistance may be available to cover the cost of necessary repairs to ensure compliance with emissions standards. If repairs are impractical or costly, CAP may offer incentives for vehicle retirement, directing them to designated dismantlers for responsible recycling.

This program serves as a crucial tool in advancing clean air efforts and diminishing vehicle emissions in California. It extends support to low-income individuals who may face challenges in maintaining their vehicles in accordance with emissions standards.

What is a Smog Check?

All vehicles that are over 8 years old must undergo a Smog Check every other year. Moreover, if you are registering an out-of-state vehicle for the first time in California or selling a car over 4 years old, you must mandatorily get a check. The DMV will let you know whether a Smog Check is required or not in your registration renewal form.

The emissions test has been designed to assess the level of pollutants emitted by your vehicle, ensuring compliance with California’s standards. The test itself will consist of;

  • A Visual inspection of the exhaust system
  • A functional inspection of the Check Engine Light, Ignition System, Exhaust Gas Recirculation System, Fuel Evaporation System and the Gas Cap
  • A Functional Inspection of the Diagnostic Systems
  • Tailpipe Emissions Test
