CarbAudit exists for one reason: California's Clean Truck Check program is complex, and most fleet owners don't have time to figure it out alone.
The Clean Truck Check program requires every heavy-duty diesel truck operating in California to register with CARB, pass periodic emissions inspections, and submit quarterly reports. The rules change. The deadlines don't.
We handle the paperwork, the portal, the reporting schedule, and the regulatory monitoring so you can focus on running your fleet. No jargon. No runaround. Just a clear path to compliance.
CarbAudit helps California fleets navigate CARB Clean Truck Check compliance.
