Know what’s behind the CTC regulation.

The California Air Resources Board (CARB) is tasked with safeguarding the public’s health from harmful air pollution spearheading initiatives that combat climate change.

CARB’s Clean Truck Check (CTC) regulation aims at reducing smog-forming and carcinogenic air pollutants to make the air healthier and meet federal air quality mandates. This regulation combines regular vehicle testing with advanced emissions monitoring and enhanced enforcement to identify vehicles that need emission-related repairs. And ensure repairs are completed in a timely manner.

Enforcement is scheduled to commence January 1, 2025.

Clean Truck Check enforcement timeline

Comply without complexity or extra downtime.

The CTC regulation requires scans at different 90-day intervals per vehicle, depending on the vehicle’s attributes (VIN or date of registration).

  • Two scans are required per year within the vehicle's individual due dates.
  • Each needs to be performed by either your in-house technicians, third party vendors or during a shop visit.

Zonar Emissions Check is our service that ensures scans are performed on time, without a costly logistical nightmare. We share the data with only your permission and will not provide it to CARB unless required.

Set up remote scans.

Compliance deadlines dictate scan deadlines based on registration. The scan deadline is 6 months after the expiration date of California registration. If the vehicle is not registered in California, scan eligibility will be determined based on the last digit of the VIN.
