Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements. Welcome to our South Dakota CDL Combination Practice Test, one of several we offer! This intuitive tool will help you pass the official combination vehicles knowledge test on your first attempt. It consists of 25 multiple-choice questions based on the official Commercial Driver License Manual (South Dakota CDL Handbook 2025), specifically Section 6 (Combination Vehicles). A minimum score of 80% is required to pass.
Commercial driving theory can be a complex subject, especially for those who are new to this industry. Mistakes are common amongst beginners, and they are a normal part of the learning process. Unlike other practice tests that reveal your score at the end, ours updates in real time. If you make a mistake, we will immediately point it out so you can learn from it before proceeding to the next question. A detailed explanation of the correct answer will be revealed shortly after you select an answer. Please pay attention to this feedback and note it in a notebook or notebook app for future reference.
Customize your testing experience with the test settings menu, which includes several features. You can access this menu by clicking the three dots in the top-right corner of the page. This menu also includes a slider for adjusting the font size. Use it to make the text bigger and prevent eye strain from occurring. This practice test is untimed, so you can take as long as you need to answer all questions. Read every question twice and carefully consider each answer choice before you select one.
Incorporating practice tests into your study routine can make the difference between passing and failing your theory exams. While this practice test will help you understand combination vehicles, our Free South Dakota CDL Permit Practice Test can be used for mastering general commercial driving theory.
Take the first step today and make your dream career a reality. Dedicate the following weeks to your learning phase and improve your knowledge one question at a time. On exam day, you’ll go to the DMV location ready to ace your theory exams on your first attempt.
