About the North Carolina CDL test

NCDMV confirms the minimum ages of 18 for intrastate operation and 21 for interstate commerce or hazardous materials, but does not publish the number of items or the pass mark for the general knowledge test. The count and pass mark shown follow the common federal 80 percent standard and are listed as unconfirmed.
