Welcome to our Hawaii CDL Class B Practice Test! Consisting of 50 multiple-choice questions, this intuitive tool closely reflects the content and format of the official general knowledge exam. You get unlimited attempts and nonstop access to practice as often as your schedule allows. As you begin your learning phase, we recommend training with this tool on a daily basis. Pair it with the official Hawaii Commercial Driver License Manual (Hawaii CDL Handbook 2026) and see your knowledge naturally improve over the following weeks.
This practice test can be used to evaluate your knowledge before exam day. It can also be used as an educational resource if you are unfamiliar with commercial driving theory. Unlike other practice tests that show your score at the end, ours updates in real time. Identify mistakes as soon as they occur and use the detailed explanations to strengthen your knowledge. This feedback can help you understand the reasoning behind each correct answer, making it easier for you to remember and recall important information.
We frequently update this practice test (most recently for January 2026), so you will always use the latest version. However, we recommend checking the official HI DMV website for the most up-to-date information. For your convenience, we have removed any timer from this practice test. Please finish each session at your own pace and avoid rushing. Remember, mastering commercial driving theory is a gradual process, not a race against time.
