SC CDL General Knowledge Exam Simulator 2025

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 April 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 April 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.

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
