Aspiring commercial drivers often use the official Commercial Driver Manual (Oregon CDL Handbook 2026) as their primary study resource. Published by Oregon’s Driver & Motor Vehicle Services (DMV), this handbook discusses the various aspects of commercial driving theory in detail. We recommend reading its contents multiple times during your learning phase. If you plan to drive tanker vehicles, you should focus on Section 8 (Tank Vehicles).
The official Tank Vehicles knowledge exam has 20 multiple-choice questions. You must answer all questions and score 80% or higher to pass. Our Oregon CDL Tanker Vehicles Practice Tests are designed to help you ace this exam on your first attempt. You’re about to take the second practice test in this series. Train with it anytime, anywhere in the world, using a compatible device connected to the internet.
In Oregon, aspiring commercial drivers completed 1,640 practice sessions this week. They train with practice tests instead of relying on traditional study methods. You can adopt a similar approach to boost your learning potential and study efficiently. Whether you can spare a few minutes during a busy day or schedule an extended study session over the weekend, you’ll have the flexibility of training on your own schedule.
