From the bustling streets of Portland to the winding mountain roads of the Cascades, Oregon’s roads present a unique challenge to new commercial drivers. Driving a commercial vehicle safely in this state requires more than basic driving skills. Those pursuing a Class B CDL (Commercial Driver’s License) must dedicate several weeks to complete the licensing process. The DMV oversees this process and requires all applicants to pass several exams, a vision screening, and a medical examination (unless they only plan to engage in excepted commerce).

It’s the best.
The questions are almost same words like at DMV. I would recommend it to all my friends and family. Also Andrei and Marina are very good in their job. Marina communicated with me almost immediately when I had a problem. The training program is very well made. I passed 2 endorsements after 2 days of training, English being my second language.
AS

I enjoy a "hands-on" learning experience. The website fully enforces the "building block" principle of learning. Great job! Follow up: Since writing my review I took 4 Oregon DMV CDL tests, and passed them all.

About the Oregon CDL

The official general knowledge test consists of 50 multiple-choice questions that will evaluate your understanding of safe driving practices, rules of the road, the air braking system, and handling emergencies. This exam is based on the official Oregon Commercial Driver Manual (Oregon CDL Handbook 2025), which you should read at least once during your learning phase. Since most commercial vehicles in Oregon are equipped with air brakes, you must also pass the official air brakes knowledge test to legally operate them. Each exam must be passed with a minimum score of 80%.

Our Oregon CDL Class B Practice Test is designed to support students unfamiliar with commercial driving theory. You can use it to evaluate your knowledge before exam day or as an ongoing educational resource. Each mistake becomes a learning opportunity, allowing you to review and practice until you consistently achieve passing scores. The detailed explanations will help you understand the reasoning behind each correct answer. Pay attention to this feedback and note it in a notebook or notebook app.

Start today and dedicate the following days to studying the basics from the official commercial driver manual. Use our Oregon CDL Class B Practice Test to gradually improve your knowledge and prepare for your dream career.
