Understanding the Difference Between Regular Smog Check and STAR Smog Check

California DMV smog check notice

As a vehicle owner in California, keeping up with smog check requirements is essential not just for staying compliant with state laws but also for contributing to a healthier environment. However, many drivers are often confused about the distinction between a regular smog check and a STAR smog check. At Smog Check Network, we're here to clear up the confusion and help you navigate through the requirements smoothly.


What is a Regular Smog Check?

A regular smog check is an emissions test that most vehicles in California must pass every two years to ensure they meet state emissions standards. The test measures the amount of pollutants that your vehicle emits. If your vehicle is registered in a region that mandates smog checks, you'll need to have it tested at a state-licensed smog check station.


Key Points:

  • Frequency: Every two years for most vehicles.

  • Testing: Checks for pollutants like hydrocarbons, carbon monoxide, and nitrogen oxides.

  • Location: Any state-licensed smog check station.


What is a STAR Smog Check?

A STAR smog check is a more stringent version of the regular smog check. The Bureau of Automotive Repair (BAR) certifies certain stations as STAR stations, which are subject to stricter performance standards and oversight. Vehicles required to undergo a STAR smog check are usually those that have been identified as high emitters or are randomly selected by the DMV.


Key Points:

  • Frequency: As directed by DMV notices.

  • Testing: Similar to regular smog checks but at a certified STAR station.

  • Location: Must be performed at a STAR-certified station.


Why Some Vehicles Need STAR Smog Checks

There are specific reasons why your vehicle might need a STAR smog check instead of a regular one:

  1. High Emitter Profile: Vehicles identified as having a higher likelihood of failing emissions tests.

  2. Random Selection: Some vehicles are randomly chosen to ensure compliance.

  3. Directed Vehicles: Certain model years and types of vehicles may be directed by the DMV to undergo a STAR smog check.


How to Determine Which Smog Check Your Vehicle Needs

When your vehicle registration is due, the DMV will send a renewal notice indicating whether your vehicle requires a regular smog check or a STAR smog check. This notice will guide you on where to take your vehicle for testing.


The Importance of Smog Checks

Both regular and STAR smog checks play a crucial role in reducing air pollution. By ensuring vehicles meet emission standards, California can maintain better air quality and contribute to environmental protection.


Preparing for Your Smog Check

To increase the likelihood of passing your smog check, consider the following tips:

  • Regular Maintenance: Keep up with routine vehicle maintenance.

  • Check Engine Light: Ensure your check engine light is not on.

  • Proper Warm-Up: Drive your car for at least 20 minutes before the test to ensure it is warmed up.

  • Pre-Inspection: Some stations offer a pre-inspection to identify issues before the actual test.
