SMOG CHECK FAQ
What is a Test Only Station?
State-licensed facilities exclusively for emissions testing—no repairs allowed. They can certify Gross Polluters too.
Who requires a SMOG CHECK?
Your DMV renewal notice will specify if one is required. Most California areas mandate smog checks every 2 years, during vehicle sales, or initial registrations.
Is a SMOG CHECK required for my vehicle?
Not all vehicles require a SMOG CHECK - testing depends on your vehicle's type and model year, where it's registered, and specific situations like selling the vehicle or registering it in California after being out-of-state. Most California areas require smog checks every two years for eligible vehicles.
What is a SMOG CHECK?
If your DMV renewal notice states "SMOG Certification Required at a STAR station," you've come to the right place. Premier Star Smog is a STAR Certified testing center. This designation means the DMV has selected your vehicle for inspection at a station that meets the BAR's (Bureau of Automotive Repair) highest performance standards and undergoes strict government monitoring.
What is the difference between a regular smog station and a
STAR smog station?
STAR stations are specially authorized to certify vehicles referred by the DMV for registration renewal - these stations can issue compliance certificates for DMV-directed smog checks. Regular stations can only test and certify vehicles not specifically required by the DMV to visit a STAR station.
How much does a Test-Only SMOG CHECK cost? Do they charge more?
Test-Only stations cannot perform repairs or profit beyond testing fees. While they historically charged higher prices to cover costs, today’s competitive market—coupled with ample DMV-directed Test-Only vehicles—has significantly reduced pricing.
How can I help my vehicle pass SMOG CHECK?
Follow these key steps:
Maintain your vehicle according to the manufacturer's schedule in your Owner's Manual,
Never tamper with or modify emissions control equipment,
Take a 15-20 minute drive before testing to fully warm up all emissions components,
Address any known engine issues or warning lights beforehand

What should I know about the Consumer Assistance Program
(CAP)?
You may qualify for up to $500 in financial assistance to
repair your car if it requires a SMOG CHECK at a Test-Only
station and failed that test. The Bureau of Automotive Repair
Retirement Program is now offering $1000.00 for eligible
motorists to voluntarily retire their high-polluting vehicles.
If you don’t think it’s worth repairing the Bureau of
Automotive Repair may buy your car!
How do I qualify for CAP?
CAP provides two options when your vehicle fails its required smog check: repair assistance or vehicle retirement.
What is a Gross Polluter?
A Gross Polluter is a vehicle that fails its smog check with exceptionally high emissions levels. BAR flags these vehicles to prioritize repairs, as they're among the worst polluters on California roads.
