Triple-checked for accuracy
Updated for April 2025

In Oklahoma, all aspiring commercial drivers must take the official CDL General Knowledge {permit} test. On this test, you must answer 50 multiple-choice questions before the timer ends. If you score 80% or higher, submit a Medical Examiner’s Certificate, provide the necessary documents, pass a vision test, and pay the license fees, you’ll receive a Commercial Learner’s Permit (CLP). After holding a CLP for 14 days and completing Entry-Level Driver Training (ELDT), you can schedule and take the CDL skills test, which is the last step in the licensing process.
As you begin your learning phase, you should use the most efficient resources available. Start by reading the official Oklahoma commercial driver license manual (Oklahoma CDL Handbook 2025). It contains all the information covered on the official exam, but if you want to pass on your first attempt, you should adopt a smarter approach. Boost your learning potential with the help of our Oklahoma CDL General Knowledge exam simulator, which is designed to enhance your study sessions.
The purpose of this tool is to help you familiarize yourself with the content and format of the official exam. You will not receive hints, feedback, or assistance. Furthermore, if you make too many mistakes, the test ends immediately. (However, you can still learn from your mistakes by visiting your personal Challenge Bank™. This section includes detailed explanations for all the questions you got wrong.) You will not receive help at the SOK office, where you must rely on your own knowledge. To accurately recreate the official testing experience, you should work independently and avoid external help.
Commercial driving theory can be difficult to understand by beginners unfamiliar with this subject. We recommend starting with the basic aspects, which are thoroughly described in the official Oklahoma commercial driver handbook. To strengthen your knowledge, you can practice on our other CDL practice tests. They include several features that make studying more efficient and enjoyable. At the end of your study sessions, use our Oklahoma CDL General Knowledge Exam Simulator to evaluate your knowledge and see if you’re ready to take the official exam.

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
