About the Hawaii CDL test

Hawaii issues a commercial learner's permit from age 18 but requires age 21 for the commercial driver license itself. The item count and pass mark for the general knowledge test are not published by HDOT or the counties, so the values shown follow the federal 80 percent standard and are listed as unconfirmed.
