SC CDL General Knowledge Exam Simulator 2025
In order to get your Commercial Driver’s license, the DMV in South Carolina requires that you take a General Knowledge exam. The test is 50 questions that you have to finish in less than an hour. Answer more than 10 questions incorrectly and you wash out. If you fail, you have to come back to the South Carolina DMV another day. That means waiting in line and taking the test all over again. Who has time for that. Instead, make sure you are ready to pass the test on your first visit. Get ahold of the official South Carolina Commercial Driver’s License Manual and read up on all the information that you didn’t previously know. Then, to see how these facts are used in the context of the test, you’ll want to take some practice exams. The CDL General Knowledge practice tests we offer take questions pretty much directly from the DMV, so you’ll get a great sense of how the test really works. We also offer hints and tracking so you can see where you want to work in concepts. But to get to the test itself you also need to remember to bring some documentation to the South Carolina DMV. First you’ll want to get a Medical Examiner’s certificate. This certifies that you are physically qualified to drive a commercial motor vehicle in South Carolina. Then you also need proof of citizenship or permanent residency. For this a social security card, green card, or birth certificate will do. Then lastly, you need to have a current valid driver’s license. With all your documentation in order and the confidence of knowing that you understand the test material, you will be ready for success. Start with our CDL General Knowledge practice exam so you can earn your CDL ASAP!
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements

- 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.
