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!
