What Smog Check Requires in Redding

Redding is in Shasta County, which is part of California's Northern Sacramento Valley air basin and requires smog checks for most vehicles. If you register or renew registration for a vehicle model year 1976 or newer in Shasta County, you will need a passing smog check certificate before the DMV will process your registration. Diesel vehicles model year 2000 and newer also require smog checks; older diesels do not.

The test itself measures your vehicle's emissions of nitrogen oxides and particulate matter. A licensed smog technician performs the test at a Bureau of Automotive Repair (BAR) certified station. The test takes about 10 to 15 minutes and costs between $30 and $80 depending on the station and your vehicle type.

Redding has multiple certified stations throughout the city. You can find them by searching the BAR's online station locator at bar.ca.gov or by calling a local repair shop to ask if they perform smog checks.

Key Takeaways

  • Shasta County requires smog checks for vehicle registration if your car is model year 1976 or newer, with limited exceptions for electric vehicles and some older models.
  • You must pass the test before the DMV will issue or renew your registration; a failed test means you cannot legally register the vehicle until repairs are made.
  • The test costs $30 to $80 and takes about 10 to 15 minutes at any BAR-certified smog station in Redding.
  • If you fail, you have 30 days to repair your vehicle and retest at no additional charge at the same station.
  • Vehicles that fail twice in a row may be subject to California's Gross Polluter Program, which can restrict your ability to register the vehicle.

When You Need a Smog Check in Redding

You need a smog check when you register a vehicle for the first time in California or when you renew your registration. In Shasta County, smog checks are required every two years at registration renewal. If you just moved to Redding from another state, you will need a smog check as part of your initial California registration.

Some vehicles are exempt. Electric vehicles, vehicles model year 1975 and older, and vehicles with fewer than 6,000 miles on the odometer do not require smog checks. Diesel vehicles model year 1999 and older are also exempt. If your vehicle falls into one of these categories, ask the smog technician to confirm before you pay for the test.

You do not need a smog check straightforward to drive your car around Redding. The requirement only applies at registration time. However, if your vehicle fails a smog check, you cannot legally register it until you fix the problem and pass a retest.

Finding a Smog Check Station in Redding

The California Bureau of Automotive Repair maintains a searchable database of all certified smog stations. Visit bar.ca.gov and use the station locator tool. Enter Redding as your city and it will show you every certified station near you, along with their phone numbers and hours.

You can also call local repair shops and ask whether they perform smog checks. Many independent mechanics and tire shops in Redding are certified to do the work. Some stations are faster than others, so calling ahead to ask about wait times can save you a trip.

When you call, confirm that the station is BAR-certified and ask about their current price. Prices vary slightly between stations but should fall in the $30 to $80 range. Some stations may charge extra for certain vehicle types, such as diesels or vehicles with aftermarket equipment.

What Happens If You Fail the Smog Check

If your vehicle fails the smog check, the technician will give you a report showing which emissions standards your vehicle did not meet. You have 30 days from the test date to repair your vehicle and return to the same station for a retest. The retest is free if you return within 30 days.

Common reasons for failure include a faulty oxygen sensor, a malfunctioning catalytic converter, or a check engine light that is on. Some repairs are straightforward and inexpensive; others can cost several hundred dollars. A repair shop can diagnose the specific problem and give you an estimate before you authorize work.

If you fail the smog check twice in a row, your vehicle may be flagged in California's Gross Polluter Program. This can restrict your ability to register the vehicle and may require additional repairs or inspections. If this happens, contact the BAR or your local air quality management district for guidance on next steps.

Smog Check Timing and Registration important date

Plan to get your smog check at least one week before your registration expires. The smog check certificate is valid for 30 days, so if you test too early, the certificate may expire before you can submit it to the DMV. The DMV will not accept an expired smog check certificate.

You can submit your smog check certificate to the DMV online, by mail, or in person at a local DMV office in Redding. If you submit online or by mail, allow extra time for processing. If you are close to your registration expiration date, going to the DMV in person is faster.

If your registration expires before you complete the smog check and registration renewal, you cannot legally drive your vehicle. Plan ahead, especially if your vehicle has failed a smog check in the past and may need repairs.

Cost and Payment at Smog Check Stations

The smog check test itself costs $30 to $80 at certified stations in Redding. This is the only fee you pay to the smog station. If you pass, you receive a certificate and can proceed with registration. If you fail and return within 30 days for a retest, there is no additional charge for the retest.

Payment methods vary by station. Most accept cash and credit cards. Call ahead to confirm what payment methods the station accepts, especially if you plan to pay by check or electronic transfer.

The cost of repairs, if your vehicle fails, is separate from the smog check fee and depends entirely on what is wrong with your vehicle. A repair shop will give you an estimate before you authorize any work. Some repairs may be covered by your vehicle's warranty if it is still under coverage.

What if I move out of Shasta County but still own a vehicle registered here?

If you move to another California county, you will need to update your registration with the DMV. Some counties have different smog check requirements. Contact the DMV or your new county's air quality district to learn what is required for your new location.

Do I need a smog check if I buy a used car from a private seller in Redding?

Yes. When you register the vehicle in your name, Shasta County will require a smog check before the DMV issues your registration. The seller does not need to provide a smog check; you obtain one after you purchase the vehicle and before you register it.

How long does a smog check certificate last?

A smog check certificate is valid for 30 days from the test date. You must submit it to the DMV before it expires. If it expires before you complete your registration, you will need to get a new smog check.

What should I do if a smog station tells me my vehicle cannot be tested?

Some vehicles with significant damage, missing parts, or safety issues cannot be tested. If this happens, ask the technician what the specific problem is. You may need to repair the vehicle first or take it to a different station. Contact the BAR if you believe a station refused to test your vehicle without valid reason.
