CARB Truck and Bus Reporting Window Open Now

We just wanted to provide a friendly reminder that the California Air Resources Board’s (CARB) Truck and Bus reporting system for heavy duty diesel trucks is now open.  The Truck and Bus Regulation is set to sunset in 2023, at that point, all vehicles older than 2010 must be retired, junked or sold out of the state.  Over the past year, CARB has sent out over 50,000 enforcement letters to non-compliant fleet/truck owners, forcing them to comply with mileage limitations or sell the equipment outright and pay a significant fine for being out of compliance.  Please note that there are changes to the current mileage limitations for agricultural compliance options.  The significant changes include the Low Use Exemption being lowered from 5,000 miles per year down to 1,000 miles per year, and the Agricultural Mileage Extension dropping from 10,000 miles per year down to 5,000 miles per year.   If you have any questions, please feel free to reach out to Chris McGlothlin with CCGGA at (559)-252-0684, or by email at
