The people of Hawaii may be separated by islands, but they all need certain products, from different islands and the mainland. That makes commercial drivers a necessity, which is why getting your CDL is a great choice. Today, you’ll be one step closer to that goal, once you practice for the real CDL written exam with our carefully crafted practice test. These 50 multiple-choice questions, based on the Hawaii Commercial Driver License Manual, cover the material the Hawaii Department of Transportation feels you must know to pass your exam, such as braking techniques, driving in special weather conditions, emergency preparedness, and more. Use the hints included with each question, and pay close attention to the questions’ explanations, as they will help you answer future questions about these topics. Good luck with your CDL exam, and remember to drive safely!

The questions and answers on our free, online Hawaii CDL General Knowledge and Endorsement permit practice tests and our other available resources are far superior to the PDF CDL manual alone. They will help prep you to pass the written tests for a Class A, B, or C Commercial Learner’s Permit (CLP) and all desired endorsements.
