Georgia Truck Emissions & Clean-Truck Rules
Georgia does test vehicles, but not yours. The Clean Air Force program in 13 metro Atlanta counties covers gasoline cars and light trucks rated 8,500 lb GVWR or under; diesels are exempt regardless of model year, and anything heavier falls outside the rule (Ga. Comp. R. & Regs. 391-3-20-.03). So a heavy diesel answers only to the federal EPA engine standard (40 CFR Parts 86/1036/1037). Keep the DPF and SCR intact. Federal anti-tampering penalties run up to about $45,000 per engine.
