South Carolina CDL Class A Practice Test 2025

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

Commercial drivers are essential to South Carolina’s economy, helping transport everything from construction materials to consumer goods. Whether navigating I-26 between Columbia and Charleston or hauling freight along I-95, you must drive responsibly and prioritize safety at all times. Before you can take the driver’s seat, you must fully understand commercial driving theory.

The first step is passing the official general knowledge exam, which is required for a Commercial Learner’s Permit (CLP). This exam includes 50 multiple-choice questions based on the official South Carolina Commercial Driver License Manual (South Carolina CDL Handbook 2025). To pass, you must score 80% or higher. To get a Class A CDL, you must also pass the official combination vehicles knowledge exam. You should also pass the air brakes knowledge test to drive trucks equipped with air brakes.

Our South Carolina CDL Class A Practice Test can help you prepare efficiently. All 93 questions have multiple answer choices, but only one is correct. After you select an answer, you’ll receive a detailed explanation that helps you understand the reasoning behind the correct answer. This feedback can help you learn from your mistakes as soon as they occur, so you won’t have to wait until the test ends to know what went wrong. For future reference, you should note this feedback in a notebook or notebook app.

If you make a mistake, we will automatically add the missed question to your personal Challenge Bank™. This section stores every question you answered incorrectly. You can revisit your Challenge Bank anytime you want to practice with the questions you struggle with. Once you answer a question correctly, it will be removed from your Challenge Bank, so you can focus only on the areas that need improvement.

Whether you’re new to commercial driving or returning to the industry, mastering commercial driving theory is the first milestone in the licensing process. Our South Carolina CDL Class A Practice Test can significantly boost your learning potential, but you must use it regularly to pass the official general knowledge test on your first attempt.

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.
