About the North Dakota CDL test

The North Dakota Commercial Driver License Manual confirms that a Class A, B or C license cannot be issued below age 18 except at 16 for custom harvesting, and that age 21 is required to drive a commercial vehicle across state lines. It does not publish the number of items or the pass mark for the general knowledge test, so those figures follow the common federal 80 percent standard and are listed as unconfirmed.
