Oregon CDL Class A Practice Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 OR commercial driver's license manual
  • Triple-checked for accuracy
  • Updated for August 2025

Studying commercial driving theory doesn’t have to be a chore, especially if this is your dream career. Some complex topics might confuse students who are unfamiliar with this subject. Understanding and staying compliant with federal rules is essential but difficult. Hours of Service (HOS) regulations involve detailed rules about maximum driving limits, 34-hour resets, and mandatory rest breaks. Optimizing your schedule can be difficult, so you should plan ahead and learn all parts of commercial driving theory.

The Oregon Commercial Driver Manual (Oregon CDL Handbook 2025) is an official resource published by the Department of Motor Vehicles (DMV). You should read its contents multiple times during your learning phase. This manual lays the foundation for your commercial driving skills, but many students use practice tests to improve their knowledge through active learning.

Our Oregon CDL Class A Practice Test has been designed to closely reflect the content and format of the official written knowledge test. It consists of 93 multiple-choice questions similar to the ones you will encounter at the DMV office. It is impossible to predict the actual questions you’ll receive on exam day. Memorizing the correct answers without understanding them won’t prepare you for situations where you need to apply what you’ve learned. Instead, you should use the detailed explanation provided for each question to strengthen your knowledge and learn the reasoning behind each correct answer.

You get unlimited attempts and nonstop access to our practice tests. Train with them as often as your schedule allows and use the features available to customize your experience. If you have difficulty reading the text, you can use the slider from the test settings menu to adjust the font size. Make the text bigger until it becomes easier to read, so you won’t have to strain your eyes.

Becoming a successful commercial driver in Oregon takes time and effort. As you begin your learning phase, we recommend developing and consistently following a daily study routine. Use our Oregon CDL Class A Practice Test alongside the official commercial driver manual to boost your learning potential. Within a few weeks, you’ll be ready to ace the official written knowledge test on your first attempt.
