- 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 September 2025
Welcome to our South Carolina CDL Class B Practice Test! This intuitive tool can significantly boost your learning potential and help you prepare for your dream career. Consisting of 50 questions, this practice test closely reflects the content and format of the official general knowledge exam. All questions have multiple answer choices, but only one is correct. They are based on the official South Carolina Commercial Driver License Manual (South Carolina CDL Handbook 2025), which you should read multiple times during your learning phase.
If you’re unfamiliar with commercial driving theory, you’re more likely to make mistakes. Do not let a failed attempt discourage you. With unlimited attempts and nonstop browser-based access, you can begin a new practice session right away. We give students the opportunity to learn from their mistakes by providing immediate feedback for each question. Once you select an answer, a detailed explanation will be provided. Please pay attention to this feedback and note it in a notebook or notebook app for future reference.
Updated for September 2025, this practice test includes the most recent updates brought by DMV rules or state law. The official SC DMV website has the most up-to-date information on this subject. You should check this website occasionally, even after obtaining your CDL. Unlike the official general knowledge exam, this practice test is not timed. You can finish each practice session at your own pace. Read every question twice and only select an answer when you’re confident of your choice. As long as you’re not in private browsing mode, your progress will be automatically saved.
When enabled, the answer popularity feature displays the percentage of students who selected each option. This insight helps you identify difficult questions where misconceptions are common, so that you can focus your study more effectively. You can activate this feature and several others from the test settings menu, which can be accessed by clicking the three dots in the top-right corner of the page.
Every skilled commercial driver started as a beginner. Your knowledge can only be improved gradually, so there’s no point in rushing your studies. Dedicate plenty of time to your learning phase and master this subject with the help of our South Carolina CDL Class B Practice Test.
