View All PlansWelcome to our South Dakota CDL Class A Practice Test, an intuitive tool designed to help you master commercial driving theory. It includes 93 multiple-choice questions based on the official South Dakota Commercial Driver License Manual (South Dakota CDL Handbook 2025). You must score 80% or higher to pass. Unlike the official general knowledge exam, this practice test is not timed. Please avoid rushing and finish each session at your own pace.
A detailed explanation of the correct answer is provided for every question. Use this feedback to learn from your mistakes and identify areas that need improvement. Commercial driving is a complex subject that cannot be learned overnight. Your knowledge will be improved gradually over the following weeks. During this time, we recommend developing a study routine you can follow consistently.
You get unlimited attempts and nonstop access to our practice tests. They can be accessed on any device that supports a browser and has a stable internet connection. Your progress will be saved automatically as long as you’re not in private browsing mode. If you must interrupt an active session, you can resume it later. Customize your testing experience with the test settings menu. You can access this menu by clicking the three dots in the top-right corner of the page. The voice-over function can help you focus even when studying in distracting environments. Once activated, an artificial voice will read the questions and answer choices aloud.
Our South Dakota CDL Class A Practice Test can also be used for educational purposes. Beginners unfamiliar with commercial driving theory should ignore their score during the initial stages of their learning phase. You can use this intuitive tool alongside the official commercial driver license manual to improve your knowledge and study efficiently.
The Department of Public Safety (DMV) is strict about the licensing process, but we’ll help you become a safe and responsible commercial driver. Take the first step today and begin your licensing journey with the right tools.
