Frequently Asked Questions
What is the difference between Test Only and regular smog?
A Test Only station like Fullerton Smog Check Test Only performs smog inspections exclusively — we do not perform smog-related repairs. This eliminates any conflict of interest, since we have no incentive to fail your vehicle to sell repair work. The DMV sometimes directs vehicles to Test Only stations for this reason.
Can any smog station do STAR smog?
No. Only stations that have earned STAR certification from the Bureau of Automotive Repair can perform STAR-required smog inspections. Fullerton Smog Check Test Only is both STAR-certified and Test Only, providing the highest level of unbiased emissions testing in Fullerton.
What happens during a smog inspection?
During your smog check at Fullerton Smog Check Test Only, our certified technician connects your vehicle to a state-approved emissions analyzer. The system measures tailpipe emissions, checks your OBD-II readiness monitors, and inspects the gas cap. The entire process takes about 15–20 minutes. Results are sent electronically to the DMV.
What does the smog technician check?
The technician measures hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) from your tailpipe. They also check your vehicle’s On-Board Diagnostics (OBD-II) system for readiness monitors and stored trouble codes, and perform a visual inspection of emissions components and gas cap integrity.
