Welcome to our fourth Hawaii CDL Combination Vehicles Practice Test, the solution to your study needs! Add flexibility to your learning process with this intuitive tool, which you can access anytime, anywhere in the world. This practice test includes 25 multiple-choice questions based on the Commercial Driver License Manual (Hawaii CDL Handbook 2025), an official resource published by the Department of Motor Vehicles (DMV).

The questions in this practice test are similar to those you will encounter in the official combination vehicles knowledge test. If this is your first time taking a CDL theory exam, our practice tests will show you what to expect and help you build the confidence and knowledge to achieve a passing score on your first attempt. This systematic approach is much more effective than traditional study methods, which can be overwhelming and time-consuming.

We have recently updated this practice test for December 2025. The latest version includes the most recent updates brought by DMV rules or state law. For the most up-to-date information, you should visit the official DMV website.
