    Super helpful study tool

    This app is a great studying resource when prepping to take your CDL permit test. Before downloading it I looked at the reviews and one said to study it like it’s your bible! And that’s so true!! I read through the manual before finding this app, but I think that this allowed me to recall and really understand what I read. It’s awesome how it has a “see why” option when you miss a question. This allows you to look back at your manual and read about it. I took my general knowledge, combination and air brake tests out of Indiana. The GK test is about 90% similar to the questions they have on here. I passed and only missed a few on my first try. For the combination test, it’s about 95% similar to the questions on here. I passed on first try. I still have yet to take the air brakes but I will update after. Thanks!

    Go no further!

    Hands down this app was one of the best tools to study for the written test! I decided to get this app because I talked to a few people and they said that this test was fairly difficult and that it took some 2 times to pass. I strongly recommend reading the book first so to better understand everything you need to know because let’s face it this app is what it is a means to test your knowledge. After I went through the book and felt comfortable then I took the test. The nice thing too about the app test questions is that they are verbatim on the state test BUT they wording may be different to trick you so PAY attention and don’t assume you know the answer without reading the full question. Anyways, I passed the test first try and strongly recommend this App to help you prepare. Good luck!

    I don’t usually leave reviews. But.

    I usually hate looking at reviews because most of them are bots. But this app is the best app I found and they have all the answers. I recommend if you download this app and study then you will 100% pass the test. I just got mine today. Go through the practice 2 or 3 times then try to test. Read out loud. It sounds stupid but it helps. Take the test over and over again until your in the 96 and above Then keep going. Thanks cdl prep. I will be recommending this app to others 👍🏽👍🏽

    Some questions answers change base on location.

    I’m studying for Missouri and some of the questions coming from the California CDL are going against the cdl for Missouri or are miss quoted all together. Ex define GVWR is saying the GVW is the GVWR as in the load is the GVWR not how much it is rated to carry. Or how much should you slow down on snow packed roads the Missouri only talks about slippery roads and says 1/3 while the test quotes California saying at least 1/2 speed. I haven’t checked the California CDL book but maybe they have updated it and the test hasn’t been. Over all it’s a great way to study but maybe double checking your states CDL book against the questions if you miss it is a good thing because some being quoted for NY and CA may not be the same as your state.

    I had doubts

    At first I had doubts about the accuracy of this app.. because it was overwhelming, now it is not 100% accurate. However going through the practice test/exams numerous times, I was able to pass General Knowledge, Combinations, Air Brakes, and Tanks on my first try. **Texas resident do know YOU ARE REQUIRED to take the Special Requirements exam before they even let you take your CLP exam.** I wish this app included special requirements.. but overall very very good app. Thank you very much for creating this.

    No more doubts!

    I have used the app, and with a little time reviewing all the questions. Repeatedly over and over until you start getting them to where you get more than 80% upto 90%;correct! It doesn’t take long either. Without a doubt it will allow you to pass. I got my learners permit with ease. And all the endorsements I wanted. This is what everyone needs. You can get explanations for wrong answers too!

    Software needs fixing

    I have studied and studied the questionnaires on this app. And I have found out that more than a few questions that I have memorized to be correct come out to be wrong... on the next round of doing the question I choose the answer that I memorized from the last time and it comes out that I’ve chosen wrong again.. To prove this I have screenshot the question along with the right answer. And when I came around again to answer it I chose the right answer and still comes out wrong. Not sure what’s wrong with the software but it needs to be fixed. This will not help me pass my endorsements. Thank you

    Just took the CLP

    I took the CLP yesterday, passing airbrakes and general with no issue, but missing 5 on the Combination test. I thought that I’d rushed through too fast on that test, but then I decided to look at combination specific questions through this app. Studying that just yesterday evening showed me that I had missed a few things in the manual —retaking Combinations just a moment ago, I passed with flying colors (didn’t get a single one wrong). Thanks CDL prep!

    Downloaded this app yesterday. Took the practice and exams all day/night. Touched up and re-did everything while waiting at the DMV. Passed missing only a few questions total for my Class A permit. Most (if not all) questions on this app are on the permit test. The ones I got wrong on the app were on the test. Luckily I went over it numerous times till I got it right.

    Love the app, Hate the adds

    I love this app, I am passing General Knowledge, Combinations, and Airbrakes every time. I just had the toward the end of my exam, with at least 10 questions remainin, and Add pops up and once I click out of the add, my exam was finalized without an opportunity to finish the last 10 questions. Happens every time. But I still give this app 5 stars!!!

  • By

    This would be 5 stars but...

    The only thing that I don’t like about this app is when I’m taking an exam sometimes I accidentally click the back button and it takes me out of the exam and there’s no way to go back onto the exam. That’s so stupid!!!! Why can’t you pick up where you left off at if you still have time on the clock? Or how about taking away the back button and making an exit button somewhere. This has happened to me several time.

    Extremely helpful!

    Great app! Much easier to learn from than reading the manual. The practice mode is great because it will show you what you got wrong and highlight the sections of the manual so you can reference the book. The exam modes are great as well. This app helped me pass my A class test in a week and a half of studying! Strongly recommended!

    I give five star for this app

    Really helped me a lot, I tried others apps but they have so many questions/answers and they are not helpful ,if it is possible you should make Car/motorcycle Dmv question ans .Thanks I will recommend to everyone who want to pass cdl Dmv test they should read from this app .

  • By

    It worked for me

    I passed all the 3 tests. A lot of the questions are on the the actual test. I got 1 wrong on air brake/ combo because of that 1 question that wasn’t on the app. If you’re in California, you have to take the shortened class c test. So 4 tests in total. Thanks cdl prep for helping me pass. I have my permit and one step closer on a career.
