New York Truck Emissions & Clean-Truck Rules
No state heavy-truck emissions inspection touches you here. New York adopted California's Advanced Clean Trucks rule (6 NYCRR Subpart 218-4), but it binds manufacturers selling new trucks, not your out-of-state rig rolling through. DEC granted enforcement discretion for model years 2025 and 2026, so real enforcement starts around model year 2027. Your duty is federal: keep the DPF and DEF/SCR working. Deleting emissions gear risks about $45,000 per engine under federal law.
How New York handles truck emissions
No state heavy-truck emissions inspection touches you here.

What applies to you
- Program: ACT adopter
- State rule: Adopted California's Advanced Clean Trucks (ACT) rule, a zero-emission sales mandate on truck manufacturers (6 NYCRR Subpart 218-4, within Part 218). ZEV sales ratios apply from model year 2025, but DEC issued an enforcement discretion letter (May 23, 2025) waiving penalties for manufacturers on model years 2025-2026, so real enforcement effectively begins with model year 2027. Subpart 218-4.2 was a one-time fleet census for large fleet owners, not a driver test. No state periodic emissions inspection for heavy trucks. Out-of-state drivers face no ACT test, fee, or permit. Federal EPA engine standards otherwise govern.
- Penalty: No state emissions fine binds an out-of-state driver; ACT non-compliance penalties fall on manufacturers, not truckers. Federal EPA anti-tampering penalties apply: about $45,000 per tampered engine and about $4,500 per defeat device sold or installed.
- DPF / DEF: Federal EPA equipment nationwide, never delete or tamper with it
