Do you own, operate, or dispatch heavy-duty diesel trucks in or to California?  Then you need to know that the California Air Resources Board (CARB) enforces air pollution regulations affecting all types of heavy-duty diesel vehicles operating in the State. If your vehicles are not compliant, you need to know what the current and future requirements are. If your vehicles are compliant, you may need to report to remain compliant. This course gives you information about how to comply with CARB diesel regulations and how to report to continue operating legally in 2023 and beyond.
