OK CDL General Knowledge Exam Simulator 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.
