Zonar, the leader in commercial vehicle fleet health and safety, today announced the general availability of Zonar Emissions Check™, a new solution that enables on-route compliance, reduces downtime, and lowers third-party operational costs. For existing customers with the Zonar V4™ telematics control unit (TCU) already installed, the compliance process is ready to seamlessly be activated with integrated Emissions Check services.

In July, Zonar received certification from California Air Resources Board’s (CARB) Clean Truck Check (CTC) program as a provider of continuously connected remote on-board diagnostic (CC-ROBD) testing devices. This certification allows Zonar to utilize its V4 TCU to conduct emissions scans on vehicles that meet CARB’s CTC requirements.

Emissions Check simplifies fleet operations and eliminates the need for dispatch to reroute drivers to testing facilities or require maintenance teams to run additional tests. This saves fleets significant time and money, while streamlining the process by only sharing Emissions Check data directly with CARB, when required.

“We’re excited to bring this solution to market to support fleets in meeting important regulatory compliance, but also to help meet long-term emissions and sustainability goals,” said Greg Colvin, senior director of solutions engineering at Zonar. “Emissions Check delivers accurate pass/fail results without taking vehicles offline for testing, enhancing fleet efficiency and productivity.”

When Emissions Check is paired with diagnostic and predictive fault code reporting with Zonar FaultIQ®, customers can also receive notifications of emission faults to fix before potential testing failures for a full end-to-end fleet health and safety solution. FaultIQ maximizes vehicle uptime by continuously monitoring fleet health, helping assets run better for longer.

The first testing window is open, and enforcement will begin on January 1, 2025.
