Alabama Truck Emissions & Clean-Truck Rules

How Alabama handles truck emissions

Alabama runs no heavy-truck emissions inspection. It has no statewide vehicle emissions program at all; the only testing is voluntary and passenger-only, in Jefferson and Shelby counties around Birmingham. Your truck answers to federal EPA engine standards, nothing more (40 CFR Parts 86/1036/1037). Keep the DPF, DEF and SCR working and undeleted. A deleted stack draws federal anti-tampering penalties up to about $45,000 per engine, in Alabama the same as anywhere.

What applies to you

• Program: Federal EPA only
• State rule: No state heavy-duty diesel emissions inspection. Federal EPA engine standards only. Alabama has no statewide vehicle emissions program; the only testing is a voluntary, passenger-vehicle program in the Birmingham area (Jefferson and Shelby counties, through Express Oil Change sites tied to Alabama Partners for Clean Air) that does not apply to trucks. Keep your DPF, DEF/SCR and OBD intact.
• Penalty: No state emissions fine. Federal EPA anti-tampering penalties apply: up to roughly $45,000 per tampered vehicle or engine and about $4,500 per defeat device sold or installed.
• DPF / DEF: Federal EPA equipment nationwide, never delete or tamper with it
