After many request CDL Study Buddy is now available on the App Store!! CDL Study Buddy is made and owned by someone who has been driving trucks for over 20 years. 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. And can be translated to over 40 languages. 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!! And instructional videos that help guide you through every step of the pretrip inspection, air brake inspection, and even a DOT roadside inspection. One of the most common questions I receive is "Does your test cover the material for my state?". 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. So study with confidence and use my free app that has already helped over 60,000 people study for and pass their written test. ## Key features - 1,000+ practice test questions - All US CDL handbooks (PDF) - CDL handbook audio versions - Instructional inspection videos - Translated to over 40 languages ## Is CDL Study Buddy safe?

I went over 500+ questions on the app. There were several questions on the test that I never saw on CDL Study Buddy and there were several questions that had the wrong answers in the app. Don’t let this be the only app you use to study with. ### 1/5 — Trash *2019-06-18* Trash ### 3/5 — Great Content !! Too Many Ads *2019-06-05* This has great practice questions and it’s helped me a lot, however there are WAY too many ads which is distracting. It also freezes half way through the middle and I have to restart the practice tests over again. If they could get rid of the ads, fix the glitches and add video content for CMV Pre-Inspection practice test, I will give this app 5 stars ### 5/5 — Study buddy app. *2019-05-07* Works great for me. Ads are annoying but hey it’s free and for me was an excellent means of tracking my progress! Obviously you still have to study but since you can measure your progress so easily it builds confidence in your ability to pass the necessary tests. ### 1/5 — Keep crashing *2019-03-10* I like the app but I have to delete it do to it keep crashing ### 5/5 — CDL A permit *2018-08-27* Passed general , air, combo, double & trip. Thanks to this app. Most all the question on my exam were on this practice test. Location MASS. AND it’s free ### 5/5 — Want let me do any practice test *2017-08-14* I had been studying every since June 2017 and every time I went to take the test I failed it went back last week and I passed passenger and school bus now I have to get general knowledge and air brakes done. But for some reason I can't get the app to let me get to the practice test ### 1/5 — No good *2017-08-13* Crap can't get to the audio that is what I need , to hell with your practice test ### 5/5 — Let's just say I pasted everything today !!!!! *2017-07-18* Using this application helped major time, I'm in California Oakland. I have been studying for like two months. I used this app and all its features. As well read the commercial handbook 2017 and past all my endorsements. ### 1/5 — Not up to date on your manuals *2017-06-02* I'm a manager at a CDL test site in Indiana. Very nice app, but you need to make sure all your manuals are up to date. The Indiana manual is not. If they give me the 4 point brake check in the old manual that you provide they will fail their air brake test ## Frequently asked questions about CDL Study Buddy ### Does CDL Study Buddy cover my state's CDL material?
