Before You Test

Georgia's Clean Air Force (GCAF) recommends testing your vehicle four to six weeks prior to the registration renewal date (the vehicle owner's birthday) to allow ample time for any needed repairs and retests.

See the testing requirements for 2024 registration.

Begin with reviewing the Emissions Testing and Vehicle Registration Frequently Asked Questions and Answers below. You’ll find answers to the most frequent questions we receive from motorists like you.

For even more information, including how to prepare for your test and tips to avoid a long wait, please check out the additional resources below.

  • For 2024 vehicle registration, if your vehicle is a 2000 – 2021 model year gasoline-powered car or light-duty truck (8,500 pounds gross vehicle weight rating or less) registered in Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding or Rockdale County, it must be emissions tested.

    The three most recent model year vehicles are exempt from emissions testing each year. For registration in 2024, this includes all 2022 and newer model year vehicles.

    Additionally, vehicles that are 25 model years or older are exempt from emissions testing. This includes 1999 or older model year vehicles for 2024 registration. View a list of all vehicles that are exempt from emissions testing.

    View information on non-conforming status (examples include gray market vehicles, kit cars, hot rods, and vehicles for which the owner is unable to obtain parts to repair the vehicle to pass the emissions inspection).

    Things to remember:

    A vehicle’s model year is determined by the vehicle identification number (VIN).

    Certain exemptions and extensions may apply to your vehicle (see below).

    Motorcycles, recreational vehicles (RVs) and motor homes do not require emissions testing for registration.

    Diesel vehicles do not require emissions testing for registration.

    License plates can be renewed online using DRIVES e-Services, at a self-serve kiosk (if your county participates) or at your county tag office.

  • The three most recent model year vehicles are exempt from emissions testing. For registration in 2024, this includes all 2022 and newer model year vehicles (2022, 2023, and 2024).

  • If you buy a used vehicle that will be registered in a covered county*, sellers located within the 13-county testing area must ensure the vehicle has a passing Georgia vehicle emissions inspection at the time of sale. A vehicle inspection report (VIR) can be used for the initial registration and one registration renewal if still valid.

    *Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding and Rockdale.

    Sellers are not required to provide the buyer with a hard copy of the VIR. The VIR will be on record electronically at the tag office.

    To file a complaint against a seller (located within the 13-county testing area) for failing to have a passing emissions test at the time of sale, go to the Forms and Applications section and complete the Used Vehicle Sale Complaint Form.

    If you purchased a vehicle that received a failed emissions test, significant costs may be incurred to correct the cause of the failure or to qualify for a waiver.

    Within 12 months, a vehicle may be sold numerous times using the same valid VIR.

  • If you are registering your vehicle for the first time in a covered county*, please contact your county tag office for the registration requirements.

    *Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding and Rockdale.

    Note: Keep a copy of your passing vehicle inspection report (VIR) for future reference.

  • Aside from Repair Waivers, you may qualify for certain extensions or exemptions from testing, such as:

    • Senior Exemption - Seniors 65 years old or older whose vehicle meet certain additional requirements may be eligible for a Senior Exemption.

    • Out-of Area-Extension- If you and your vehicle are temporarily located well outside of the metro Atlanta area because you are a student, in the military or have business obligations, you may qualify for an Out-of-Area Extension.

    • Antique Collector Vehicles - Vehicles 25 model years old or older are exempt from emissions testing. For registration in 2024, this includes vehicle model years 1999 and older.

    • If your vehicle fails its annual emissions inspection, please have all related taxes and fees ready. Then visit your local county tag office for information about a possible non-renewable 30-day extension on your registration, per OCGA 40-2-20.

    Waivers, exemptions, and extensions are covered in full in the Motorists’ Waivers, Exemptions, and Extensions section of this website.

  • Dedicated alternative fueled vehicles are vehicles that can only operate on alternative fuel and are not capable of operating on gasoline. These vehicles do not require an emissions inspection.

    Dedicated vehicle types that operate only on the following fuels are considered alternative fuel vehicles and do not require an emissions inspection:

    • Natural Gas

    • Propane

    • Battery Electricity

    • Hydrogen

    The following hybrid vehicles are not alternative fuel vehicles and therefore require an emissions inspection (Note: this is not a complete list):

    • Ford Escape

    • Honda Insight

    • Honda Civic

    • Honda Accord

    • Lexus RX

    • Mercury Mariner

    • Toyota Highlander

    • Toyota Prius

    • Bi-Fueled Vehicles

    Bi-fueled vehicles that are capable of running on either the alternative fuel (propane or natural gas) or gasoline must be tested on gasoline, even if the vehicle is always operated on the alternative fuel.

    Note: Any vehicle that is capable of using gasoline to operate requires an emissions inspection.

    DOR is now exclusively handling the determination of which vehicles are eligible for the alternative fuel tag. For more information on this subject, contact the Motor Vehicle Division at 1-855-406-5221 or with respect to the income tax credits, contact the Taxpayer Services Division at 1-877-423-6711, from 8:00 a.m. to 4:30 p.m. EST, Monday through Friday, excluding holidays.

  • Your vehicle must be tested every year prior to its registration date (the vehicle owner's birthday). For registration in 2024, the three most recent model years are exempt from emissions testing, which includes 2022 or newer model year vehicles.

    Vehicles 25 model years old or older are exempt. For registration in 2024, this includes model years 1999 or older. The registration renewal insert provides information regarding registration renewal.

    Test early. GCAF recommends having your vehicle inspected four to six weeks prior to the registration renewal date. Vehicles can be tested well in advance if the owner of the vehicle will be out of the area at the time of registration. As a reminder, an emissions inspection is valid for 12 months or one registration renewal, by the same owner. GCAF recommends contacting your tag office to determine if they will allow a registration renewal prior to the normal renewal period (more than 60 days prior to the motorist's registration renewal date, which is the owner's birthday).

  • Generally, you must have your vehicle tested and registered within 30 days after moving to one of the 13 covered counties.

    If you have just moved to one of the 13 covered counties* from a Georgia county where emissions testing is not required and your vehicle has a current Georgia registration, a valid emission certificate will not be required until your next registration renewal due date.

    If you are a new Georgia resident: You must register your vehicle in Georgia. Before you can register, you must have a valid Georgia driver's license or ID. You must apply for a Georgia driver license and register your vehicle within 30 days of becoming a Georgia resident. For license assistance, visit the Georgia Department of Revenue website.

    *Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding and Rockdale.

  • No. The test results are valid for 12 months or one registration renewal, but only by the same owner.

    Newly-purchased used vehicle registrations: If a motorist purchases a used vehicle with a valid passing VIR, that VIR (from the previous owner) can be used for the initial registration and can be used for the new owner's registration renewal, as long as the test is still valid (must not exceed 12 months). Only the most recent VIR is considered.

  • If your vehicle has not been registered for several years and you are registering late for the previous year, 2023, the vehicle will need to be tested now for the late renewal and again for the current renewal in 2024.

    If the vehicle has not been registered for several years and you are registering for the current year, 2024, the vehicle will only need to be tested once to return it to the regular testing cycle. It is the tag office's discretion as to what is required for late registration. Please contact your tag office for specific information regarding your vehicle's registration.

  • GCAF recommends the vehicle be tested four to six weeks prior to the registration renewal date; however the vehicle may be tested earlier if needed. A vehicle inspection report (VIR) is valid for 12 months or one registration renewal, by the same owner. GCAF recommends contacting your tag office to determine if they will allow a registration renewal prior to the normal renewal period (more than 60 days prior to the motorist's registration renewal date, which is the owner's birthday).

  • An emissions inspection costs up to $25 and the fee is posted on the station's emissions inspection sign.

  • For a complete listing of all vehicle testing locations, view the Testing Locations section.

    Testing tips:

    • You are not required to have your vehicle inspected in the county where your vehicle is registered.

    • Warm up your engine to make sure the emissions control equipment is working properly prior to inspection.

    • You have the right to observe the inspection as it is performed.

  • All subject vehicles will receive a three-part inspection:

    • An OBD test to check the vehicle's emissions control performance history.

    • A fuel cap inspection to check for adequate seal.

    • A visual inspection of the catalytic converter to check for tampering or removal.

    An inspector can reject a vehicle for testing if it is considered unsafe to test. If the test has already begun when the safety problem is detected, the inspector may charge the full price of the test.

  • Well-maintained vehicles usually pass the emissions test first time unless there is a component failure that has not been repaired or manufacturer's defect. Standards have been set to take into consideration the age of your vehicle as well as the emissions control components available at the time your vehicle was manufactured. If your car does fail, it must be repaired and retested.

    You will receive one free retest if you return to the original inspection station within 30 calendar days of your initial inspection (Note: 30 days includes the date and the time of your initial inspection).

    If your vehicle fails the inspection, be sure to obtain a copy of the Question & Answer brochure from the testing station or click here to view the Q&A brochure for repair tips.

    Also, you can review a copy of the RepairWatch Public Report, which lists qualified repair facilities with a proven track record of performing effective emissions-related repairs.

    Please note: If your vehicle fails its annual emissions inspection, please have all related taxes and fees ready. Then visit your local county tag office for information about a possible non-renewable 30-day extension on your registration, per OCGA 40-2-20.

    • If the "Check Engine" or "Service Engine Soon" light is on, your vehicle should be checked by a repair technician as soon as possible. This light notifies motorists when something in the emissions control system fails or begins to deteriorate. Early diagnosis and repair can prevent more costly repairs in the future.

    • Keep in mind the most common reasons for emissions test failures include: a malfunction in the components of the vehicle that regulate the fuel/air ratio such as the oxygen sensor and the EGR valve; a dirty air filter; misfiring spark plugs; leaks in the vacuum system; or a poor-fitting fuel cap. Many of these components can be checked and repaired during routine tune-ups.

    • Follow the manufacturer's recommended maintenance and tune-up schedule.

    • Have the vehicle's oil changed regularly.

    • Replace the fuel cap securely after filling up. A loose fuel cap allows water and foreign material to collect, causing rust and a poor seal.

    • Keep the sealing surfaces of the fuel cap clean and in good condition. When necessary, clean them with water and a damp cloth.

    • Keep the vehicle's tires properly inflated.

    • Check belts and hoses for wear.

    • The "Check Engine" light may illuminate as a result of a loose fuel cap. If the "Check Engine" light is illuminated, try tightening the fuel cap until it clicks, then drive the vehicle until the light turns itself off.

    A properly maintained vehicle gets better fuel economy than a poorly maintained one. Furthermore, an improperly maintained vehicle may lead to a compromised emissions control system and not be effective in removing or reducing harmful air pollutants. This could result in not passing the emissions test. Make sure your vehicle is ready and help keep Georgia's air clean.

    Note: Federal law requires that emissions control systems on 1995 and newer model year vehicles be warranted by the manufacturer for two years or 24,000 miles. Federal law also requires that the OBD computer and catalytic converter on 1995 and newer vehicles be warranted by the manufacturer for eight years or 80,000 miles. Many vehicle manufacturers provide extended warranty coverage beyond what is required by federal law. Consult your vehicle owner's warranty manual for coverage information.

  • Only vehicles registered in a Georgia county requiring emissions testing need an emissions test in order to renew their vehicle's registration. Please contact your home state for emissions requirements.

  • There is no need to mail the results of your emissions inspection because they are transmitted electronically to the tag office. When renewing online, the system will search for a current, valid inspection. If one is detected, you will be allowed to complete your renewal without having to enter the certificate number from the vehicle inspection report (VIR). Should you have further questions regarding your registration, please contact your tag office for assistance.

  • Visit the EPA website with a list of Vehicle Emissions Inspection and Maintenance (I/M) programs in other states.

  • No, an emissions inspection from another state is not transferable and is not acceptable for Georgia registration. While Georgia does not accept other states' emissions tests for registration purposes, GCAF does accept them as a proof that the vehicle is out of area.

  • GCAF recommends having your vehicle inspected four to six weeks prior to the registration renewal date. Vehicles can be tested well in advance if the owner of the vehicle will be out of the area at the time of registration. As a reminder, an emissions inspection is valid for 12 months or one registration renewal, by the same owner. GCAF recommends contacting your tag office to determine if they will allow a registration renewal prior to the normal renewal period (more than 60 days prior to the motorist's registration renewal date, which is the owner's birthday).
