Starting January 2025, according to the CARB CTC Program, all diesel and alt vehicles must meet strict emission standards. Register your fleet on the CTC portal by December 31, 2024, and pay the annual fee per vehicle to avoid DMV registration holds. Prepare for bi-annual emissions testing in 2025, increasing to quarterly in 2027. Non-compliance could result in fines or operational restrictions. Stay ahead by identifying your testing windows and avoiding delays.
