This General Knowledge practice exam contains another 50 questions based on the official CDL manual and updated for January 2025. These questions are designed to prepare you for the General Knowledge portion of your South Dakota Commercial Driver’s License exam. As with our other tests, all questions are multiple-choice, with three possible answers for each question. Only one of the answers is correct. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers. The practice tests are not timed, so you can take as long as you need to answer each practice question. We recommend that you always check each question’s explanation to gain further insight into the rule being tested. Each question on this CDL practice test also offers a hint, so if you’re stuck on a question, you can use this tip to help you figure out the correct answer. Good luck!
