LA CDL General Knowledge Exam Simulator 2025

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

In Louisiana, all aspiring commercial drivers must pass the official CDL General Knowledge (permit) test and meet several other requirements before they can obtain a Commercial Learner’s Permit (CLP). This exam consists of 50 multiple-choice questions based on the official Louisiana commercial driver license manual (Louisiana CDL Handbook 2025). To pass, you must score 80% or higher. As exam day approaches, it is perfectly normal to feel anxious. However, you shouldn’t let such negative emotions discourage you. To maximize your chances of obtaining a passing score on your first attempt, you should develop a study routine and follow it consistently.

Most students no longer use traditional study methods; they prefer modern tools that enable active learning and make learning more efficient. Our Louisiana CDL General Knowledge Exam Simulator is designed to closely reflect the content and format of the official exam, allowing students to simulate the official testing experience on their devices. You must answer 50 questions and score at least 80% to pass, but please do so at your own pace. We have omitted any timer from this simulator for your convenience. If you make too many mistakes, the test ends immediately. Before you begin another training session, you should visit your personal Challenge Bank. This section includes detailed explanations for all the questions you got wrong during your previous training sessions.

Although a high score is required to pass the official exam, it is still not enough for a successful career. As you begin your learning phase, your primary goal should be to become a safe and responsible driver. Take your time and don’t rush through your study sessions. Use our other CDL practice tests to strengthen your knowledge and master commercial driving theory, as they include several educational features. Keep track of your progress and use our Louisiana CDL General Knowledge Exam Simulator to estimate your level of preparedness. Once you consistently achieve scores of 80% or higher, it will indicate you’re ready to go to the OMV office and take the official exam.

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.
