SC CDL General Knowledge Exam Simulator 2025

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

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 December 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.

I passed my hazmat test with a 100.
I highly recommend this website. They have the CDL manual, by the testee state, to read or download and a three hour video course. The video course essentially covers the same topics as the CDL manual but in more detail. There's five practice exams, marathon exam that covers all 190 questions, and the DDS hazmat simulator. There's a challenge bank that keeps all the question that the testee might struggle on.

Finished all test below 45 mins.
I tried to take the CDL knowledge test and endorsements with only reading the drivers study book from DMV and failed miserably. I had to find something quick to pass these test. I found driving-tests.org and what a great website. I played around with the practice tests and I said to myself this is just like the DMV test. So I went ahead and studied for 2 days getting 100% on all the practice tests and exams. I took the test at DMV with confidence and pass all 5 test to get my permit and the endorsements plus my real ID.

I gave driving-tests.org 5 stars….
(I wish there was something higher than 5 stars) because the program was very user friendly and I had fun learning. I started it eleven days before my written CLP (commercial learner permit) tests for Class B which included general knowledge, air brake, and passengers endorsement. I took the tests on October 25th and passed with flying colors so I now have my CLP with "P" endorsement. I had the DMV manual and it was so overwhelming to me so that is why I did a Google search for CDL tests and I found your company.

5 STARS This IS NOT Fake NEWS!
I decided to roll the dice and try to pass before then. I took my CDL exam on Feb 3rd. I also took the School Bus, Passenger and Air Brake endorsement exams. I am happy to say that i passed all the exams with flying colors! I literally got 100% on the general knowledge test. I am generally a very good test taker but I can assure you that without this website and all of the practice tests, I would have failed miserably. The CDL book from DMV is awful. You cannot read that and think you're gonna pass. Just an FYI: I tried some of the free practice tests online from other sites. They are NOT the same as the test questions on the real exam. The practice questions on this site were mostly identical to the real questions on the test. You will not regret it.
