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.

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.

After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
