About the Ohio CDL test

The Ohio Commercial Driver License Manual does not publish the item count or the pass mark for the general knowledge test, and the Ohio BMV web pages could not be retrieved. The count, pass mark and minimum age shown here follow the common federal 80 percent standard and are listed as unconfirmed.
