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 2025) 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 December 2025), 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.

Was absolutely scared because a lot of the guys that was in.
I was absolutely scared because a lot of the guys that was in my class failed but they also used another CDL program. I appreciate this site. I do wish I can watch the videos now that I did pass because I need refresher once in awhile and also would like the rules always someone I can find it easier. Thank you.

Reading the MVA learners manual seemed….
Reading the MVA learners manual seemed like a torture that would be used in a Turkish prison. It often contradicted itself. Using your program was a major improvement. I set my test date, your program made sure I was finished the day before the test. I liked being able to go back and retake different sections(air brakes, school bus, passenger, general) at any time. I highly recommend this program. Passed my CDL first time. Thanks

Absolutely amazed with this study….
Absolutely amazed with this study program.. I spent 1 day reading the manual and 2 days going through the study program. Walked into the DMV yesterday and passed all my CDL test with confidence. The ladies at the desk said no on has ever completed them so quickly. Every answer was like a muscle reflex. Highly recommend this to anyone for any type of driving test.

From Stressed OUT TO Stress Free.
I had used the samples that were given to help me make a decision on whether I should spend the money for the help of questions for the endorsements I needed. I decided to take the combo and doubles/triples on my own. That was a definite struggle and a lot of nerve racking guessing, but I did pass. When I got home I decided I was not going to do that on the Tanker test which I had left to go. I signed up and it was such a difference. I only studied one day with driving-tests.org and took the tests and passed it quickly and was done! I would definitely suggest taking the stress out and purchase this product, it really does help a lot.

Passed on the first try with no problems.
I won the riding test for Hazmat & Tankers in the first try, the questions was 95% accurate. I'll come back in almost 5 years to get ready for my renewal.
