New Mexico Truck Emissions & Clean-Truck Rules
New Mexico adopted Advanced Clean Trucks, a zero-emission truck sales quota on manufacturers from model year 2026. It puts no test, fee, or permit on you as a driver. Auto dealers lost their court challenge in 2024, but Congress revoked California's underlying waiver in June 2025, so whether the rule can be enforced is now unsettled. New Mexico runs no heavy-truck emissions inspection you must pass. Keep your DPF and SCR intact; the delete ban is federal.

What applies to you
- Program: ACT adopter
- State rule: ACT adopter: a manufacturer ZEV sales quota phasing in from model year 2026, with no driver obligation. The federal waiver behind it was revoked by Congress in June 2025, so whether the rule can be enforced is now uncertain. No state heavy-truck emissions inspection you must pass. Federal EPA standards apply.
- Penalty: No state truck emissions fine (ACT binds manufacturers, not drivers). Federal EPA anti-tampering penalties apply: about $45,000 per tampered engine and roughly $5,000 per defeat device sold or installed.
- DPF / DEF: Federal EPA equipment nationwide, never delete or tamper with it
