View All PlansWelcome to our Free Hawaii CDL Combination Practice Test! Designed to boost your learning potential, this intuitive tool helps you improve your knowledge through active learning. Its content and format are similar to the official combination vehicles knowledge exam. All 25 questions are based on Section 6 (Combination Vehicles) of the official Hawaii Commercial Driver License Manual (Hawaii CDL Handbook 2025). We highly recommend reading this manual multiple times during your learning phase to familiarize yourself with the basics of commercial driving theory.
All of our practice tests are available online, 24/7. You can access them on any compatible device that supports a browser. You will need a stable internet connection at all times. The test settings menu is located in the top-right corner of the page. Opening it will give you access to several features and a slider for adjusting the font size. If you activate the voice-over function, an artificial voice will read the questions and answer choices aloud. This feature is helpful for students with auditory memory or those who study in crowded environments where distractions are common. You can also pair this feature with the ambient music feature to further eliminate distractions.
“Officer Frank,” our automated assistant, will be present during your training sessions. This AI coach can provide personalized help at your request. If you encounter a difficult question, “Officer Frank” will give you hints that nudge you in the right direction without revealing the correct answer. Additionally, this personal assistant can provide real-life examples and even rephrase questions so you can understand them better.
If your wireless mouse runs out of battery charge, you can finish an active practice session by exclusively using your keyboard. The “Shift + ?” key combination will display a complete list of shortcuts. Use these shortcuts to answer questions and control features.
Your knowledge can only be improved gradually, so we highly advise against rushing. On average, it takes several weeks to master a new subject. Our Free Hawaii CDL Permit Practice Test can help you become an expert in commercial driving theory, while this Hawaii CDL Combination Practice Test will teach you everything you need to know about driving semi-trucks and tractor-trailers in the Aloha State.
