To become a commercial driver in Louisiana, you must complete the licensing process and get a Commercial Driver’s License (CDL). The requirements involve passing the official 50-question knowledge test, passing a DOT medical exam, and completing Entry-Level Driver Training (ELDT). For a Class A CDL, applicants must also pass the official combination vehicles knowledge exam. To legally drive vehicles with air brakes, you must also score 80% or higher on the official air brakes knowledge test.
Students struggling with test anxiety are more likely to make avoidable mistakes due to feeling overwhelmed. Our Louisiana CDL Class A Practice Test can help you build the confidence to ace the official written knowledge test on your first attempt. This intuitive tool has 93 questions you can answer at your own pace. Each question has multiple answer choices, but only one is correct. Beginners unfamiliar with commercial driving theory can use the official Louisiana Commercial Driver License Manual (Louisiana CDL Handbook 2025) alongside this practice test to boost their learning potential and study efficiently.
The questions you get wrong will be automatically added to your personal Challenge Bank™. This section includes detailed explanations that help you understand the reasoning behind the correct answers. Visit your Challenge Bank to identify areas that need improvement and learn from your mistakes. Keep in mind that the questions in your Challenge Bank will remain there until you answer them correctly.
If you have difficulty reading the text, use the slider from the test settings menu to make the text bigger. You should also adjust your screen’s brightness and take frequent breaks to avoid digital eye strain and its uncomfortable symptoms. Mastering commercial driving theory takes time and effort. A few study sessions might not be enough for you to fully understand pre-trip inspections, safe driving practices, and the air brake system. As you begin your learning phase, you should dedicate a few days to studying the basic aspects and several more weeks to train with our Louisiana CDL Class A Practice Test.
