SC CDL General Knowledge Exam Simulator 2025
Eager to start your career as a commercial driver in South Carolina? This career path involves great responsibility, so you must be prepared to pass rigorous tests and training. When you apply for a Commercial Driver’s License (CDL), you must complete Entry-Level Driver Training (ELDT) from a provider who is listed in FMCSA’s Training Provider Registry (TPR). Besides providing the necessary documents, passing a vision screening, and paying the application fees, aspiring commercial drivers must also pass a 50-question CDL General Knowledge exam. All questions have multiple answer choices, but only one is correct. You must score 80% or higher before the timer ends, leaving little room for mistakes. To ace it on your first attempt, we provide an intuitive tool that can completely change your learning journey.
Our South Carolina CDL General Knowledge Exam Simulator is available online 24/7. You can access it on any compatible device that has a browser and a stable internet connection. We have recently updated this tool for May 2025, so you’ll always use the latest version available. All 50 multiple-choice questions are based on the official South Carolina commercial driver license manual (South Carolina CDL Handbook 2025). Unlike our other CDL practice tests, which you can use for educational purposes, we don’t provide any feedback in this simulator. Its purpose is to simulate the official testing experience as accurately as possible, so you should also avoid using external help. You should use this simulator only after you’ve learned the basics of commercial driving.
If you make too many mistakes, the test ends immediately. Your personal Challenge Bank™ includes all the questions you got wrong during your previous training sessions. Please visit this section to learn from your mistakes and identify areas that need improvement. Since you get unlimited attempts on our simulator, we recommend using it on a daily basis. You should incorporate the official commercial driver’s handbook, our other CDL permit practice tests, and this simulator into your study routine. If you remain consistent, you’ll be able to pass the official South Carolina CDL General Knowledge Exam within a few weeks.
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Triple-checked for accuracy
