CASTRO SMOG Test Only Station  is a State of California certified Test Only Center.  We are conveniently located  in an INDEPENDENT GAS STATION  

While you are relaxing in our waiting lounge, with fast and friendly  service, you are sure to have your car tested and returned to you quickly in 15 minutes.  If you prefer not to wait, you can drop off your car and pick it up later in the day when it’s more convenient.  There is no appointment necessary. 

Most vehicles, large or small, can be accommodated.  This includes cars, trucks, vans, limos and even RVs.  

If you are unsure how your car will perform, ask us about our 

pre-test option that is available to you. If needed, we offer two free retest within 30 days if your car doesn’t pass
