TN CDL General Knowledge Exam Simulator 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Are you ready to take the next step in your professional life? Becoming a commercial driver in Tennessee is a long and difficult process, but you’ll be rewarded with plenty of opportunities once you hold a Commercial Driver’s License (CDL). The DMV requires all applicants to pass a 50-question knowledge exam on safe driving practices, vehicle inspections, and traffic laws. To pass this exam, you must score 80% or higher within a time limit. As you begin your learning phase, you should study the official Tennessee commercial driver license manual (Tennessee CDL Handbook 2025). Although it is the main reference for aspiring commercial drivers, other tools can make studying easier and more efficient.

Our Tennessee CDL General Knowledge Exam Simulator is available 24/7, and you can access it on any device that supports a browser and has an active internet connection. We have designed this intuitive tool to closely reflect the content and format of the official exam. All 50 questions have multiple answer choices, but only one is correct. Take your time and think before selecting an answer. There is no countdown, so you won’t feel the pressure of a ticking clock. If you make too many mistakes, the test ends immediately. You will not receive any insight for the questions you got wrong. However, they will be automatically added to your Challenge Bank, which includes detailed explanations and useful information that lets you learn from your mistakes.

To maximize the chances of passing the official test on your first attempt, we recommend dedicating a few weeks to your learning phase. During this time, you should master all aspects of commercial driving theory through repetition and consistent practice. Since you get unlimited attempts on our simulator, you can develop a daily study routine that includes the official commercial driver license manual and our CDL practice tests. These resources will help you refine your knowledge, while the Tennessee CDL General Knowledge Exam Simulator lets you simulate the official testing experience on your device.
