OBD-II Scan
Direct read of your vehicle's onboard diagnostic computer for stored emissions codes and readiness monitors.
Services & Pricing
Whatever your DMV letter
says, we test for it.
Five services, one flat and posted price list. No hidden fees, no "diagnostic charge," no surprise add-ons at the counter.
Most Common
Test-Only Smog Check
The standard biennial or change-of-ownership check required by the California DMV for most gasoline vehicles model year 2000 and newer.
WHO NEEDS THIS
- Renewing registration on a standard schedule
- Buying or selling a used vehicle
- No prior DMV flags or referral requirement
Visual Inspection
Quick check of your gas cap, check-engine light, and emissions-control hardware for tampering or damage.
Instant E-File
On a pass, your certificate is filed with the DMV before you leave the lot — no paper to mail in.
State Required
STAR Station Smog Check
A more rigorous test performed only at licensed STAR stations — required when the DMV directs your vehicle to one, or when a prior test flagged an issue.
WHO NEEDS THIS
- Your renewal notice says "STAR station only"
- Your vehicle is registered as a "high emitter"
- You're randomly selected under the state's rotation
Every STAR test is signed off by a licensed technician
STAR-certified doesn't just mean the equipment — it means the person running your test has passed state licensing and is personally accountable for the result the DMV receives.
