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 started January 1, 2025.
compliance with remote, onboard scan
fleetwide & per vehicle compliance online
faults before compliance deadline
complex logistics & third-party costs
The CTC regulation requires scans at different 90-day intervals per vehicle, depending on the vehicle’s attributes (VIN or date of registration).
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.
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.
Emissions Check performs the required scan on schedule.
Identify vehicles that may fail their upcoming emissions scan. And know about component problems that need fixes before having a successful rescan.
View daily fault diagnostic reporting, already included in Ground Traffic Control. And use Zonar FaultIQ®, to predict potential faults that would impact the vehicle’s emissions. All within a single pane-of-glass user experience, within a single, end-to-end solution.
The less time ensuring compliance takes, the more time you have to focus on running your fleet. Instead of taking a vehicle offline for its scans, rely on our CARB-certified TCU, the Zonar V4™, to provide the live engine data Emissions Check needs to deliver accurate pass/fail results.
Not all telematics control units (TCUs) are the same. Nor do they all deliver high-quality data. Our Zonar V4 TCU collects precision live engine data that provides reliable, real-time insight into your fleet’s inner workings.
