Before you make the trip
CAN WE INSPECT
YOUR VEHICLE?
Check your DMV notice first. Requirements depend on the vehicle’s model year, fuel type, weight rating, and the type of inspection DMV requested.
Standard Smog Check
Gas, hybrid and alternative fuel
We perform standard Smog Checks and emissions repairs for applicable vehicles. California commonly requires testing for gasoline, hybrid, and alternative-fuel vehicles model-year 1976 and newer, subject to current exemptions and DMV direction.
Light-duty diesel
Many 1998 and newer diesels
California generally includes model-year 1998 and newer diesel vehicles with a gross vehicle weight rating of 14,000 pounds or less. Call with the year, make, model, fuel type, and GVWR so we can confirm.
VSSI
DMV-directed safety inspections
We perform Vehicle Safety Systems Inspections, commonly required for revived salvage or junk vehicles and certain registration transactions. Call before your visit and bring the DMV or CHP paperwork you received.
Does your notice say “STAR station required”?
The Smog Dawg is not currently STAR-certified. If your DMV renewal notice specifically directs you to a STAR station, you will need a STAR-certified location. If it does not, call us and we’ll help confirm whether we can inspect your vehicle.
Vehicle eligibility and inspection rules can change. Your DMV notice and current BAR requirements control.

Vehicle Safety Systems Inspections
SAFETY.
SYSTEM BY SYSTEM.
The Smog Dawg is a Vehicle Safety Systems Inspection station for vehicles that need California’s comprehensive safety certification.
A VSSI checks the systems that help keep the vehicle—and everyone around it—safe. The inspection includes:
- Body structure
- Brakes and lights
- Passenger compartment
- Steering and suspension
- Tires and wheels
- OBD scan, recalls, and road test
One electronic certificate
When an applicable vehicle passes, BAR issues an electronic certificate of compliance. For affected registration transactions, this replaces the former separate brake and light certificates.
VSSI is commonly required for revived salvage or junk vehicles and certain other vehicle types. DMV determines the documents and inspections required for each registration transaction.
Official BAR reference
Review California BAR’s official VSSI inspection procedures and minimum standards for lighting, brakes, tires and wheels, steering and suspension, body structure, passenger-compartment systems, OBD checks, recalls, and the road test.
OBD-II readiness monitors
“NOT READY” CAN MEAN
NOT READY TO TEST.
Readiness monitors are the vehicle computer’s emissions self-tests. A Smog Check reads their status to see whether the applicable systems have completed testing.
What resets them?
Disconnecting or replacing the battery, clearing diagnostic codes, or completing certain emissions repairs can return monitors to “not ready.”
How do they complete?
Many complete through normal driving. Others need specific speed, temperature, engine-load, and drive-cycle conditions described by the manufacturer.
How do they affect Smog Check?
Too many incomplete monitors can prevent a vehicle from passing. California’s allowance depends on model year and fuel type, and certain vehicles have BAR-recognized exceptions.
Before your Smog Check
- Check OBD-II readiness before you arrive. A basic scan tool can show which monitors are Ready, Not Ready, or not supported. “Not Ready” means the self-test has not finished—it is not the same as a diagnostic trouble code.
- Avoid disconnecting the battery or clearing codes immediately before the inspection; either action can reset completed monitors.
- After a battery disconnect or emissions repair, allow time for a cold start plus mixed city and highway driving. The exact procedure varies by year, engine, fuel type, and manufacturer.
- If the check-engine light stays on or a monitor will not complete, diagnosis or a manufacturer-specific drive cycle may be needed.
A check-engine light that remains illuminated while the engine is running will fail the OBD portion of a Smog Check. Readiness rules and vehicle-specific exceptions can change; contact the station for current guidance.
