- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 SC commercial driver's license manual
- Triple-checked for accuracy
- Updated for August 2025
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.
