Louisiana CDL Class A Practice Test 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

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.

Application is very, very well thought out, and the user.
The application is very, very well thought out, and the user interface is really good to where you can navigate easily. You know, you can go from next step to next step. The questions were great. There's a lot that I did know, and there's a whole bunch more that I did not know. So that just really prepared me for, you know, walking into the DMV, scheduling an appointment, and passing it the first time.

Passed so easily.
I passed so easily, thanks to this course. I was well prepared and now I have my X endorsement. They have every test question that I encountered on the Louisiana tests.

I love this website.
It helped me pass my Washington state CDL exam-airbreaks, doubles and triples and tankers. I’m using it now to study for my hazmat. My daughter uses it to study for her regular drivers license for Louisiana. I would recommend it to anyone needing practice test for all DMV needs!

Go slow take your time and read the questions.
I didn’t know what to think being a first time CDL. only driving a pickup truck all my life. I listened to the book and thought I’m never going to pass. but when I started taking the practice test it all started to fall into place. after completing all tests I made a appointment at the DMV ( that’s the hardest part is to make sure you have all documentation or they will not let you take the test) I sat down and did not miss a question. ( take the practice test until you can read the question and know the answers before your done reading the question)

I love the way you teach!
I learned quickly, had great helps and explanations, and received lots of encouragement to keep going. A great way to learn all this CDL information! Plus you provided the specific state manual I needed. So glad I purchased the 2 week plan, as I contracted the flu 2 days after starting, and had to dive back into it days later. But it still gave me time enough to learn and succeed!

Great Prep.
I wanted a good review for my upcoming tests to renew my CDL endorsements. We had a new driver taking the test for the first time and also had a family member that failed the driving test the first time, struggled to get much out of just reading the manual, and lacked the confidence to schedule another test. We had done other online free tests, but they were not very comprehensive. I was pleasantly surprised! All of us passed our tests with flying colors. The questions were very similar to the real test.
