About CDL Study Buddy

1. And the answer is yes it does, this is because every state in the United States uses the cdl handbook that is produced by American Association of Motor Vehicle Administrators (AAMVA), and thus the reason you'll see something to the effects of "copyright, AAMVA" in your CDL handbook.

2. In addition to over 1,000 test questions, CDL Study Buddy also provides every CDL handbook throughout the United States in pdf, as well the the CDL handbook in audio so you can listen to it on the go!!

3. One of the most common questions I receive is "Does your test cover the material for my state? ".

5. And then there is the instructional videos that help guide you through every step of the pretrip inspection, air brake inspection, and even a DOT roadside inspection.

6. I've taken everything that has ever helped me, my friends and even those I've chosen to teach how to drive, and then placed it into a simple to use lightweight app.

7. And now in over 40 languages with the help of Google Translate.

CDL Study Buddy Customer Insights

1. Besides, my phone is a 8gb RAM and 256gb memory running on Android 9.0.by far cdl study buddy is the all time best cdl study app .... It is when you are busy doing things that reading a book style is not possible but cdl study buddy does both reading and ( AUDIO ) super nice to be able to cook food or be on a treadmill while listening to the CDl book AUDIO .....And very pro style training videos .

2. one question was incorrect on the app but actually the right answer when I looked into it.The app keeps freezing up and can't ever finish test ... I tried the contact us and it won't send .... do wish it worked right what I've seen I likeMan you need to go back and rewrite every question because almost everyone of them is written with poor grammar.

3. Although I have already sat down and read the CDL truck driving book several times.Ok, the app stop the practice test and back to home page in the middle of the test.

4. So learning everything that's in this book through audio means, I am so grateful to the audio book and the online book also it's the same thing.

5. REALY like that i can clean my house and do my excercize while listening to the CDL book on AUDIO .

6. Audio is much easier for me than having to sit down and read a book.

7. Mind you, I also did this online using my computer and the same problem occurred, hence my conclusion.

8. this app also does the reguler reading way also ,App developers go a little to crazy with ads.

9. When the ads affect your ability to use the app then its junk! So many ads you cant even see what you are trying to read.

10. Almost time to renew my license, as soon as my prints are done I'll review the hazmat again.

11. LolThis app got me thru all the CDL tests, including hazmat.
