Fast and Affordable Smog Checks
Vehicle owners are required to get a smog check every 2 years. Laws regarding Smog Checks change often and previous exceptions do not hold up today. Current Smog Check exemptions include 1975 or older gas cars, 1997 or older diesel cars, and electric vehicles.
If your check engine is on there might be an issue with your vehicle or pending code that will prevent it from passing the Smog Check. If this is the case with your vehicle, let us first diagnose and fix the issue before conducting a Smog Check. Sometimes it can be a low cost fix, other cases may be more intensive.
Speedy Smog Check Service
At Rocha’s, we always strive to get you and your vehicle back on the road as fast as possible. Vehicles from 1999 and older may take a little longer, but we’ll still get you safely on your way quickly.
Easy and Affordable Smog Checks
Rocha’s makes the smog check process fast, easy, and affordable. We go the extra mile to make sure your vehicle passes its inspection. Schedule your smog check today at Rocha’s Auto Service!
Do I Need an Oil Change?
Oil can be contaminated with small quantities of gas so we recommend an oil change before a Smog on 1999 or older vehicles. It isn’t necessary to get an oil change if your vehicle is 2000 or newer.

-
For vehicles from 1999 or older, we do recommend an oil change before testing. Older engines can allow small amounts of fuel to mix with the oil, which may increase emissions. Vehicles from 2000 or newer typically don’t need this extra step, but routine oil changes are always important for performance and emissions health.
-
If your car doesn’t pass, our ASE-certified team will identify why and provide a detailed estimate for repairs. Common causes include faulty oxygen sensors, catalytic converters, or evaporative system leaks. Rocha’s Auto Service offers diagnostics, emissions repairs, and retesting all under one roof, so you can get back on the road fast.
-
Here are a few steps to improve your chances:
Drive your vehicle at least 15–20 minutes before testing so it reaches operating temperature.
Make sure the check engine light is off.
Complete any recent repairs at least one week before the test.
Have regular oil changes and tune-ups done at Rocha’s Auto to keep emissions systems clean and efficient.

Most vehicles in California need a smog check every two years when registration is renewed. Some vehicles, such as electric cars or gas-powered cars from 1975 and earlier, are exempt. If you’re unsure, call Rocha’s Auto Service in Redding and we’ll help you determine if your vehicle requires a test.

Yes. When your vehicle passes or fails a smog check in California, the results are instantly and electronically sent to the DMV. There’s no need to bring in paperwork or confirmation. Rocha’s Auto Service in Redding handles the entire process for you, ensuring your smog check is quick, accurate, and fully compliant with California regulations.
-
Yes, a lit check engine light almost always means your car will fail the smog inspection. The check engine light signals an emissions-related issue that needs to be diagnosed and repaired before testing. At Rocha’s Auto, our ASE-certified technicians can perform a full diagnostic scan to identify the cause, explain the repair options, and help you get your vehicle ready to pass the smog check.
-
There’s no official limit on how many times you can retest, but each smog check costs time and money. The best approach is to have your vehicle inspected and diagnosed by our certified mechanics in Redding before retesting. We’ll pinpoint the issue, repair it correctly, and help ensure your car passes the next smog inspection.
-
Yes, it often can. When you replace or disconnect your car battery, the onboard computer resets, clearing the emissions data that smog checks rely on. Until the car completes its drive cycle and relearns sensor data, it may fail. Drive your vehicle under varied conditions (city and highway) for at least 50–100 miles before coming in for your smog check, or stop by Rocha’s and we’ll check your readiness monitors for you.
-
No. Smog tests in California only focus on your vehicle’s emissions and diagnostic systems, not safety or traction control lights. However, if you have multiple dashboard warnings active, it’s still a good idea to bring your vehicle to Rocha’s Auto Service in Redding for a complete diagnostic check to ensure there aren’t underlying electrical issues.
