What Georgia requires for emissions testing
Georgia requires emissions testing for most vehicles registered in the state, but the rules depend on where you live and what you drive. If you live in the Atlanta metro area (Fulton, DeKalb, Gwinnett, Clayton, Cobb, Henry, and Forsyth counties), your vehicle must pass an emissions test every two years. If you live outside that area, you do not need emissions testing at all.
Vehicles that must be tested include gasoline-powered cars, trucks, and SUVs that are at least 25 years old. Diesel vehicles, motorcycles, and vehicles newer than 25 years are exempt. If you own a vehicle that fails the test, you cannot renew your registration until you repair it and pass a retest.
The test itself checks your vehicle's exhaust for nitrogen oxides and particulate matter. A certified emissions testing station runs the test, which takes about 10 minutes and costs between $25 and $35. You can find testing stations through the Georgia Department of Natural Resources website or by searching for "emissions testing near me" in the Atlanta metro counties.
Key Takeaways
- Only vehicles registered in the Atlanta metro area (seven specific counties) must pass emissions testing; all other Georgia counties have no emissions requirement.
- Gasoline vehicles at least 25 years old are the main vehicles tested; diesel vehicles, motorcycles, and newer vehicles are exempt.
- Testing must happen every two years as part of your vehicle registration renewal, and you cannot renew registration without a passing test.
- A test costs $25 to $35 and takes about 10 minutes at any certified testing station in your county.
- If your vehicle fails, you have 30 days to repair it, retest, and show proof of the passing test to complete your registration renewal.
When your emissions test is due
Your emissions test is due every two years, and the due date is tied to your vehicle registration renewal. When you renew your registration through the Georgia Department of Revenue, you will be told whether a test is required. If you live in one of the seven metro counties, the answer is yes.
You can take the test up to 30 days before your registration expires. Many people test early to avoid the rush near the expiration date. The test result is valid for 30 days, so if you test too early, you may need to retest before you renew your registration.
If your registration expires before you pass the test, you cannot legally drive the vehicle. If you fail the test, you have 30 days from the failure date to repair your vehicle, retest, and pass. You will need to show the passing test result when you renew your registration.
What happens if your vehicle fails the test
A failed emissions test means your vehicle's exhaust contains too much nitrogen oxides or particulate matter. Common reasons for failure include a faulty oxygen sensor, a malfunctioning catalytic converter, a check engine light that is on, or an engine that is running too rich (burning too much fuel).
After a failure, you have 30 days to repair the problem and retest. The repair cost depends on what is wrong — a sensor might cost $100 to $300, while a catalytic converter can cost $500 to $1,500 or more. Some repair shops offer free or low-cost diagnostics to help you find the problem.
If you cannot afford the repair, Georgia offers a Repair information Program for vehicles that fail emissions testing. The program provides up to $500 toward repairs for low-income vehicle owners. You must meet income requirements and own a vehicle that is at least 10 years old. Contact your county's environmental office or the Georgia Department of Natural Resources for details on how to request information.
Finding a testing station and what to bring
Certified emissions testing stations are located throughout the Atlanta metro area. You can find one through the Georgia Department of Natural Resources website by entering your county, or you can search online for "emissions testing" plus your city name. Most stations are independent repair shops, not dealerships.
When you go to test, bring your vehicle registration and a valid photo ID. The testing station will run your vehicle's onboard diagnostic system and measure your exhaust. The test does not require you to turn off your engine or leave the vehicle — the technician does the work while you wait.
After the test, you will receive a printed result showing whether you passed or failed. If you passed, keep this receipt — you will need to show it when you renew your registration. If you failed, the result will list the specific pollutants that were too high, which can help a mechanic diagnose the problem.
Renewing your registration after testing
Once you have a passing emissions test result, you can renew your vehicle registration through the Georgia Department of Revenue. You can renew online, by mail, or in person at your county tag office. You will need your vehicle registration renewal notice, proof of insurance, and your passing emissions test result.
If you renew online or by mail, you will upload or mail a copy of your test result. If you renew in person, bring the original or a copy. The registration renewal fee varies by vehicle weight and county, but typically ranges from $20 to $50 for a standard passenger vehicle.
Your new registration sticker will be mailed to you within two weeks. You must display it on your vehicle by the expiration date of your old registration. If you do not renew before your registration expires, you cannot legally drive the vehicle and may face a fine if stopped by law enforcement.
Vehicles exempt from Georgia emissions testing
Several categories of vehicles do not need emissions testing in Georgia, even if you live in the Atlanta metro area. Diesel vehicles are exempt because they are tested under different federal standards. Motorcycles, mopeds, and other two-wheeled vehicles are also exempt.
Vehicles newer than 25 years old are exempt because newer vehicles have more advanced emissions control systems and are covered by federal emissions standards. Vehicles that are 25 years old or older must be tested if they are registered in the metro area.
If you own a vehicle that is exempt, you do not need an emissions test to renew your registration. However, you still must renew your registration and maintain valid insurance. If you are unsure whether your vehicle is exempt, contact your county tag office or the Georgia Department of Revenue.
Frequently Asked Questions
What if I just moved to Georgia from out of state?
If you move to the Atlanta metro area, you must register your vehicle in Georgia within 30 days. When you register, you will be told whether an emissions test is required. If your vehicle is subject to testing, you must pass the test before your registration is complete. If you move outside the metro area, you do not need a test.
Can I test my vehicle before my registration expires?
Yes, you can test up to 30 days before your registration expires. The test result is valid for 30 days, so if you test too early, the result may expire before you renew your registration and you will need to retest. Most people test within two weeks of their renewal date to avoid this problem.
What if I fail the test twice?
If you fail twice, you still have time to repair and retest. You have 30 days from the second failure to fix the problem and pass. If the repair is expensive, check whether you meet the income requirements for Georgia's Repair information Program, which can cover up to $500 of the cost.
Do I need an emissions test if I buy a used car from a private seller?
You need an emissions test only when you renew your registration, not when you buy the car. When you register the vehicle in your name, you will be told whether a test is required. If you live in the metro area and the vehicle is at least 25 years old, you must test before your registration is complete.
What counties in Georgia require emissions testing?
Only seven counties in the Atlanta metro area require emissions testing: Fulton, DeKalb, Gwinnett, Clayton, Cobb, Henry, and Forsyth. All other Georgia counties have no emissions testing requirement. If you live outside these counties, you do not need to test your vehicle.
