Geotab automates California heavy-duty emissions compliance

The California Air Resources Board (CARB) mandates that heavy-duty vehicles, including those registered outside California, adhere to strict Heavy-Duty Inspection and Maintenance standards. Geotab’s latest update allows its GO9 device family to automatically detect and utilize J1979-2, J1979, or J1939 protocols without requiring manual setting changes or additional hardware. This streamlined approach allows fleet managers to transmit emissions data through a single, unified platform.

Sabina Martin, VP of Product at Geotab, noted that this integration serves as a future-ready pathway for operators navigating shifting mandates. By automating the data collection workflow, companies can shift away from administrative-heavy reporting processes. As regulatory bodies increasingly move toward standardized digital frameworks, this early adoption of J1979-2 provides a technical buffer for fleets facing evolving environmental policies.
