What Hollywood Star Smog Check is and who runs it

Hollywood Star Smog Check is a smog check station in Los Angeles County that performs emissions testing on vehicles. It is a privately owned business, not a government agency — the state of California requires the test, but individual stations like Hollywood Star carry out the inspection and report the results to the state's Bureau of Automotive Repair.

The station tests whether your vehicle's emissions fall within California's legal limits. If your car passes, the station issues a certificate that you take to the Department of Motor Vehicles (DMV) to renew your registration. If it fails, you receive a report showing what needs repair, and you have 30 days to fix the problem and retest.

Hollywood Star Smog Check is one of thousands of stations across California licensed to perform this work. The state sets the testing standards and the pass/fail thresholds; the station follows those standards and sends results to the state's database.

Key Takeaways

  • Hollywood Star Smog Check performs the emissions test California requires for vehicle registration, but it is a private business, not a government office.
  • The test costs money (the exact amount varies by vehicle type and the station's pricing), and you must pass before the DMV will renew your registration.
  • If your vehicle fails, you have 30 days to repair the problem and retest at any smog check station, not necessarily the same one.
  • You can take your test results directly to the DMV in person or online, or the station can submit them electronically on your behalf.
  • Bring your vehicle registration, proof of ownership, and a valid ID; the station will need your vehicle identification number (VIN) to run the test.

When you need a smog check and how often

California requires a smog check every two years for most vehicles, timed to your registration renewal. Your registration notice from the DMV will tell you whether your vehicle is due for a test. Vehicles registered in California for the first time also need a smog check before the DMV will issue the registration.

Some vehicles are exempt: those under four years old (because they are covered by the manufacturer's emissions warranty), vehicles with a gross vehicle weight rating over 14,000 pounds, and vehicles that run on diesel fuel and are model year 2000 or newer. If you are unsure whether your vehicle needs testing, check your registration renewal notice or call the station to confirm.

If your vehicle fails the test, you must retest within 30 days. You can go back to Hollywood Star or choose any other licensed station in California. The station will report the retest result to the state, and if it passes, you can then renew your registration.

What happens during the test

The smog check itself takes 10 to 30 minutes depending on your vehicle's age and type. The technician will connect a probe to your vehicle's exhaust system and measure the levels of nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. For vehicles 1996 and newer, the test also reads the onboard diagnostic system (OBD) to check whether any emissions-related trouble codes are stored.

You do not need to do anything special to prepare, but your vehicle should be in normal operating condition — the engine should start and run without obvious problems. If the check engine light is on, the vehicle will likely fail the OBD portion of the test, and you will need to have the problem diagnosed and repaired before retesting.

The technician will give you a printed report showing whether you passed or failed. If you passed, the report is your certificate of compliance. If you failed, the report lists the specific emissions that exceeded the limit and what category of repair (fuel system, ignition system, emission control system) is likely needed.

Passing, failing, and what to do next

A pass means your vehicle's emissions are within California's legal limits. You take the certificate to the DMV (online, by mail, or in person) along with your registration renewal fee, and your registration is renewed. You do not need to do anything else.

A fail means one or more emissions readings exceeded the legal limit, or the OBD system detected an emissions-related fault code. The report will show which system is likely at fault — for example, "fuel system" or "emission control system." You then have 30 days to have the vehicle repaired and retested.

You can take the repair report to any mechanic, not necessarily one affiliated with the smog check station. The mechanic will diagnose the specific problem (a faulty oxygen sensor, a leak in the fuel system, a clogged catalytic converter) and repair it. Once repaired, you can retest at any licensed smog check station. If the retest passes, you submit that passing certificate to the DMV and renew your registration.

If you retest and fail again, you have another 30 days to repair and test again. After two consecutive failures, some vehicles become may be able to access for the Smog Check Referee Program, which allows a state referee to review the vehicle and potentially issue a waiver if repairs have been attempted but the vehicle still cannot pass.

Cost and payment

Smog check fees vary by station and by vehicle type. A basic test for a passenger car typically costs between $30 and $70, but the exact price depends on the station's pricing and whether your vehicle requires additional testing (for example, heavy-duty vehicles or those with special equipment may cost more). Call Hollywood Star Smog Check directly to ask for their current pricing.

If your vehicle fails and you need to retest, you will pay the testing fee again. Some stations offer a discount on the retest if you fail the first time, but this is not required by law — ask the station whether they offer this option.

Payment methods vary by station. Most accept cash and card, but confirm with Hollywood Star what they take before you arrive.

How to submit your results to the DMV

Once you have a passing certificate, you have three ways to renew your registration. The fastest is usually online through the DMV website (dmv.ca.gov) — you can upload your certificate or provide the certificate number, and complete the renewal in minutes. You can also mail the certificate and renewal fee to the DMV, or visit a DMV office in person.

Many smog check stations, including larger operations, can submit your results electronically to the state on your behalf. Ask Hollywood Star whether they offer this service. If they do, you may not need to do anything — the station sends the result, and you can renew your registration online or by mail without handling the paper certificate.

Do not wait to submit your results. Once you have a passing certificate, renew your registration as soon as you can. If your registration expires before you renew, you cannot legally drive the vehicle, and you will owe late fees when you do renew.

What to bring and how to prepare

Bring your vehicle registration, proof of ownership (title, registration card, or insurance card), and a valid photo ID. The station will need your vehicle identification number (VIN), which is on your registration and on the dashboard at the base of the windshield on the driver's side.

Make sure your vehicle is in normal operating condition. If the check engine light is on, have it scanned by a mechanic before you go to the smog check station — the test will likely fail if a trouble code is stored. If your vehicle has not been driven in a while, take it for a 15-minute drive to warm up the engine and clear any temporary fault codes before testing.

Arrive during the station's business hours. Most smog check stations do not require an appointment, but calling ahead to confirm wait times is a good idea, especially during busy periods.

Frequently Asked Questions

Can I test my vehicle at a different smog check station if I fail at Hollywood Star?

Yes. You can retest at any licensed smog check station in California. You do not have to return to the same station. However, you must retest within 30 days of the failure date shown on your test report.

What if my vehicle fails the smog check twice?

After two consecutive failures, your vehicle may be may be able to access for the Smog Check Referee Program. A state referee can review your vehicle and, if repairs have been attempted in good faith, may issue a waiver that allows you to renew your registration even if the vehicle does not pass. Contact your local Bureau of Automotive Repair office to request a referee inspection.

Do I need to make an appointment at Hollywood Star Smog Check?

Most smog check stations do not require appointments and test vehicles on a walk-in basis. However, wait times vary. Calling the station ahead of time to ask about current wait times is a good idea, especially during peak hours or at the end of the month.

What if the smog check station submits my results but I never get a certificate?

If the station submitted your results electronically, the result is in the state's system and you can renew your registration online or by mail without a paper certificate. If you need a paper copy for your records, ask the station to print one or contact the Bureau of Automotive Repair to request a copy of your test record.

Can I renew my registration before I get my smog check?

No. California law requires a passing smog check certificate before the DMV will renew your registration. If you try to renew online or by mail without a passing test result, the DMV will reject your renewal and ask you to submit the certificate.
