WA CDL General Knowledge Exam Simulator 2025
Before obtaining a Commercial Learner’s Permit (CLP) in Washington, all aspiring commercial drivers must pay the license fees, pass a vision test, undergo a medical exam, provide the necessary documentation, and pass a 50-question CDL General Knowledge exam. All questions are based on the official Washington commercial driver guide (Washington CDL Handbook 2025), which you should read at least once. It contains important information on the various aspects of commercial driving theory, including pre-trip inspections, safe driving practices, air brakes, and transportation of hazardous materials. After holding a CLP for 14 days and completing Entry-Level Driver Training (ELDT) from a registered training provider, you can take the CDL skills test.
The most determined students prefer to adopt a smarter approach and seek alternatives to traditional learning methods. When you enable active learning, any subject becomes easier to study as you naturally improve your knowledge with practice. Our Washington CDL General Knowledge Exam Simulator helps you familiarize yourself with the content and format of the official exam. You must answer 50 multiple-choice questions and score 80% or higher to pass, but there is no time limit to complete the test. You will not receive any assistance during your training sessions, and we also recommend avoiding external help. The purpose of our simulator is to help you evaluate your knowledge and identify areas that need improvement. Although you won’t receive any explanations for the questions you get wrong, you can get useful insight from your personal Challenge Bank™. This section includes detailed explanations for all the questions you got wrong during your previous sessions.
You can restart an active session at any time by clicking on the “Restart test” button. Since you get unlimited attempts, there’s no limit to how many sessions you can start in a day. Use this tool to bring flexibility to your study schedule, allowing you to practice anytime, anywhere. Our simulator not only prepares you for the official CDL General Knowledge (permit) test but also helps you become a safe and responsible commercial driver.
