You failed your SMOG check, your vehicle is unusual, or a regular station simply refuses to test your car. Now what? California's Bureau of Automotive Repair (BAR) runs a little-known resource called the BAR Referee Program, and for many drivers it is the key to resolving a SMOG situation that a standard station cannot handle. Understanding when and how to use a referee station could save you from registration holds, unnecessary repairs, or hours of confusion.
What Is the BAR Referee Program?
The BAR Referee Program is a network of state-contracted inspection stations that handle SMOG check cases that fall outside normal procedures. Referee stations are not ordinary smog shops. They are staffed by specially trained technicians who follow BAR protocols designed for complex, disputed, or unusual vehicle situations. The program exists because California's fleet of registered vehicles is enormously diverse, and a single standard testing process cannot fairly cover every scenario. Referee stations can perform inspections, resolve disputes, and issue certificates that a regular station is not authorized to provide.
When Should You Use a BAR Referee?
Not every driver needs a referee station. But there are several specific situations where a referee is either required or strongly recommended:
- Modified vehicles: If your car has an engine swap, aftermarket performance modifications, or a non-original powertrain, a standard station may not be able to test it properly. A referee can evaluate whether the modifications meet California's legal requirements.
- Out-of-state vehicles: Vehicles originally registered in another state sometimes require a referee inspection before California will accept a SMOG certificate. This is especially common when the vehicle was never certified to California emissions standards.
- Dispute resolution: If you believe a SMOG test result was incorrect or you feel a station handled your vehicle improperly, you can request a referee inspection as a second opinion.
- Gross polluter designation: Some vehicles identified as gross polluters are directed to referee stations for a more detailed evaluation before they can receive a certificate.
- Older or specialty vehicles: Certain pre-1976 vehicles, kit cars, and other specialty registrations may need referee oversight to determine the correct test procedure or confirm an exemption.
- CAP-related referrals: Vehicles participating in the Consumer Assistance Program (CAP) may be referred to a referee station under certain circumstances. You can learn more about CAP eligibility at our CAP repair assistance page.
How to Find a BAR Referee Station
Referee stations are located throughout California. You can find the nearest location using the BAR's online station locator at bar.ca.gov. When you arrive, bring your vehicle registration, any prior SMOG inspection reports, and documentation related to any modifications. If BAR or DMV directed you to a referee station by letter or notice, bring that paperwork as well. Referee inspections are typically free of charge when you are referred by the state, though some services may carry a fee depending on the situation.
What Happens During a Referee Inspection?
A referee inspection follows the same basic SMOG check process as a regular station, but the technicians have additional tools and authority. They can visually inspect modifications, review documentation, run OBD2 diagnostics, and consult with BAR directly if a case is particularly unusual. At the end of the inspection, the referee will either issue a SMOG certificate if your vehicle passes, identify what repairs are needed, or document a dispute finding. Their results carry official weight with the DMV, which is what makes the program so valuable in difficult situations.

Common Misconceptions About the Referee Program
Many drivers assume the referee program is only for people who want to get out of a failed smog test. That is not accurate. Referees do not simply hand out passing certificates. They apply the same California emissions standards as any other station. What the program does offer is a fair, technically thorough review for vehicles and situations that genuinely fall outside the norm. If your car legitimately passes emissions standards, a referee can confirm that. If it does not, the referee will tell you what needs to be fixed, just like any other station would.
Should You Go to a Referee or a STAR Station First?
For most routine SMOG checks, especially for vehicles registered in enhanced areas like Contra Costa County, a STAR-certified station is the right starting point. You only need a referee if your situation matches one of the categories above. If your vehicle is a standard passenger car with no modifications and no prior disputes, schedule a regular SMOG test first.
