If you are considering starting a career as a commercial driver, you’re probably familiar with the official Commercial Driver Handbook (California CDL Handbook 2026). This resource discusses the various aspects of commercial driving theory in detail, including pre-trip inspections, air braking systems, emergency procedures, and the licensing process. The Department of Motor Vehicles (DMV) recommends that every aspiring commercial driver read it at least once, focusing especially on the sections most relevant to their profession.
Although this resource can help build a strong foundation for your driving skills, it often confuses beginners. Our practice tests are a great alternative to consider. They are used by many aspiring commercial drivers in California, who have completed 3,213 practice sessions today. The practice test that you’re about to take is our second California CDL Tanker Vehicles Practice Test. It is based on Section 8 (Tank Vehicles) of the official commercial driver handbook.
