Vermont Truck Emissions & Clean-Truck Rules
No state emissions test binds a passing truck. Vermont adopted the Advanced Clean Trucks rule, but Governor Scott's Executive Order 04-25 (May 13, 2025) paused enforcement through the end of 2026. Even in force, ACT targets manufacturers, not your out-of-state rig, and creates no roadside test or fee. Your real duty is federal: keep the DPF and DEF/SCR intact. Deleting emissions gear risks about $45,000 per engine in federal penalties.

What applies to you
- Program: ACT adopter
- State rule: Adopted the Advanced Clean Trucks rule, but Governor Scott's Executive Order 04-25 (May 13, 2025) directed the Agency of Natural Resources to pause enforcement through the end of 2026, provided manufacturers do not impose ZEV sales ratios on dealers. ACT is a manufacturer sales mandate, not a driver rule. No state periodic heavy-truck emissions inspection. Federal EPA standards otherwise govern.
- Penalty: No state emissions fine binds an out-of-state driver; ACT non-compliance penalties fall on manufacturers and are currently paused. 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
