Emission Testing

Effective January 1, 2019, in Cobb County, passing vehicle emission tests are required for 1995through 2016 model year gasoline-powered cars and light-duty trucks (up to 8,500 lbs. gross vehicle weight rating). The three most recent model year vehicles as exempt from emissions testing in 2019 include all 2017 and new model year vehicles (2017, 2018 and 2019). For complete information you may contact the Georgia Clean Air Force at 1.800.449.2471 or visit their website at www.cleanairforce.com.

1995-2016 model year vehicles that are newly acquired or recently moved into the county must have proof of passed inspection within the last 12 months and must be registered within 30 days (seven days if purchased from a non-registered dealer).
