To get your Commercial Driver’s License (CDL) in Kentucky, you must first obtain a Commercial Learner’s Permit (CLP). This process involves passing a vision exam and the 50-question CDL General Knowledge (permit) test, submitting the required documents, and paying the license fees. You must also submit a current medical certificate unless you will be engaged only in so-called “excepted commerce.” To comply with FMCSA regulations, the KSP requires all aspiring commercial drivers to complete Entry-Level Driver Training (ELDT) from a registered provider before scheduling and taking the CDL skills test. The General Knowledge exam will test your knowledge of the various aspects of commercial driving described in the official Kentucky commercial driver license manual (Kentucky CDL Handbook 2025). To pass, you must score 80% or higher before the timer ends.
Understanding how to control your vehicle and handle emergencies will not only help you pass the exam but also keep you and other road users safe. Our Kentucky CDL General Knowledge Exam Simulator can help you become a safe and responsible commercial driver. As you begin your learning phase, you should use this tool on a daily basis. Keep track of your scores and see them naturally improve over time. All 50 questions have multiple answer choices, but only one is correct. If you make too many mistakes, the test ends immediately, and you’ll have to start over.
Since you benefit from unlimited attempts, you can take the test as often as you need. However, we recommend checking your Challenge Bank™ occasionally, as it contains detailed explanations and useful feedback that can help you learn from your mistakes. With the voiceover feature, you can study even in distracting environments. Once activated, an artificial voice will read the questions and answer choices aloud, making it easier for you to pay attention and focus on the simulator.
The journey to obtaining a CDL may seem long at first, but any goal is within your reach. With preparation and determination, you can master commercial driving theory within a few weeks and ace the official CDL General Knowledge exam on your first attempt.
