You must be at least 18 and hold a valid driver’s license to get a Commercial Driver’s License (CDL) in California. All licensed commercial drivers are restricted from carrying passengers, transporting hazardous materials, and driving professionally across state borders until they turn 21. When you submit an application, you must also provide identification documents and pay the licensing fees. In California, you can submit your information digitally to save time at the DMV office.

Everyone must pass the official General Knowledge exam, which includes 50 multiple-choice questions about the various aspects of commercial driving. You can find more information in the official Commercial Driver Handbook (California CDL Handbook 2026). A minimum score of 80% is required to pass this exam. To achieve a passing score on your first attempt, we recommend incorporating our practice tests into your study routine.

Federal law requires all aspiring commercial drivers to complete Entry-Level Driver Training (ELDT) during their licensing process. The training provider must be registered with the FMCSA Training Provider Registry (TPR). The foundation of your career is built during this course, so you should invest the time and effort to improve your driving skills. We’ll help you with the theory part by providing you with access to our California CDL General Knowledge Practice Tests. You’re about to take the third practice test in this series.

To supplement your learning, we provide a detailed explanation for each question. This feedback describes the reasoning behind the correct answer, helping you understand the material. If you have any questions regarding a specific topic, you can ask our automated assistant. At your request, this AI coach will give real-life examples, hints, and useful insights. Do not hesitate to ask for help whenever you need it!

Take our Free California CDL Permit Practice Test before exam day to evaluate your knowledge. If you consistently achieve scores over 90%, it is a strong sign that you’re ready to pass the official General Knowledge Test. Good luck!
