What Smog Stop Roseville Does

Smog Stop Roseville is a vehicle emissions testing program run by the City of Roseville, California. It tests whether your vehicle meets state air quality standards and issues a certificate if it passes. You need this certificate to register or renew your vehicle registration with the California Department of Motor Vehicles (DMV).

The program tests tailpipe emissions — the gases your engine produces — to check that your vehicle is not releasing too much nitrogen oxide, particulate matter, or other pollutants. The test itself takes about 10 to 15 minutes and costs a set fee that the city determines each year.

Smog Stop Roseville is one of many testing stations across California that perform the same function. You do not have to use Roseville's station; you can test at any station in the state. But if you live or work in Roseville, it may be the most convenient option.

When You Need to Test at Smog Stop Roseville

California requires an emissions test before you register a new vehicle or renew your registration, with some exceptions. If your vehicle is less than four model years old, you are usually exempt from testing for the first registration. After that, you must test every two years when you renew.

You also need to test if you are buying a used vehicle from a private seller (not a dealer) and registering it in California for the first time. Dealers handle this before sale, but private sales do not.

If you move to California from another state and register your vehicle here, you will need a test. The same applies if you change your vehicle's registration from out-of-state to California.

What to Bring and How the Test Works

Bring your vehicle's current registration or proof of ownership, a valid photo ID, and payment. Smog Stop Roseville accepts cash, check, and credit or debit cards; confirm which methods they take before you arrive. You will also need your vehicle keys so the technician can start the engine and run the test.

When you arrive, you will check in and provide your vehicle information. The technician will connect a probe to your vehicle's tailpipe and run the emissions test. The machine measures the gases coming out of your exhaust and compares them to state standards. The whole process takes 10 to 15 minutes.

If your vehicle passes, you receive a certificate on the spot or within a few minutes. You can then take that certificate to the DMV to register or renew your vehicle. If your vehicle fails, the station will give you a report showing what failed and why.

What Happens If Your Vehicle Fails the Test

A failed test does not mean you cannot register your vehicle. It means you have 30 days to repair the problem and retest. During those 30 days, you can drive your vehicle to a repair shop and back home or to the test station — the law allows this for repair purposes.

When you return for a retest within 30 days, there is no additional fee. The technician will run the same test again. If it passes the second time, you receive your certificate and can register your vehicle.

If your vehicle fails a second time, you have a few options. You can repair it again and retest once more at no charge. You can also ask the station for a Referee Station referral, which sends your vehicle to a state-certified referee who can review the test results and determine if the vehicle truly fails or if there was a testing error. Some vehicles also may have access to for a Gross Polluter Abatement Program waiver if repairs would cost more than a set amount; this is rare and requires documentation from a repair shop.

Smog Stop Roseville Location and Hours

Smog Stop Roseville is located at 1650 Pleasant Grove Boulevard, Roseville, CA 95747. Hours vary by season and day of the week, so contact the station directly or check the City of Roseville website before you go. Many stations are closed on Sundays and some holidays.

If you cannot reach Roseville's station or it is closed, you can test at any other certified emissions testing station in Placer County or Sacramento County. The DMV website lists all certified stations by county. Testing at a different station does not affect your registration — the certificate is valid statewide.

Cost and Payment

The test fee varies by year and is set by the city. As of recent years, the fee has been in the range of $50 to $70, but confirm the current price when you call or visit. If your vehicle fails and you retest within 30 days, the retest is free.

Some vehicles are exempt from the test fee if they meet certain income or vehicle-age requirements. Ask the station staff whether your vehicle qualifies for a fee waiver when you arrive.

After You Pass: Getting Your Certificate to the DMV

Once your vehicle passes, you will receive a certificate. This is usually a printed form that shows your vehicle's information, the test date, and that it passed. You need this certificate to register or renew your vehicle with the DMV.

You can bring the certificate to a DMV office in person, mail it with your registration renewal form, or submit it online if you are renewing online. The DMV will not process your registration without it. The certificate is valid for 30 days from the test date, so do not wait too long to register.
