California to Officially Repeal Advanced Clean Fleets Rules - Heavy Duty Trucking

Detected July 8, 2026 · in Trucking / FMCSA Compliance

California is repealing its Advanced Clean Fleets rules, which mandated a transition to zero-emission trucks. This removes a major compliance burden for fleets operating in California.
