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.

Pass your CDL knowledge test the way real drivers actually study for it — narrated, hands-free, and built around the exact tests the DMV gives you. CDL Audible turns the commercial driver's license course into something you can listen to. Every lesson is narrated start to finish, so you can study in the cab, on a walk, or anywhere sitting down with a book isn't practical. WHAT'S INSIDE • General Knowledge, Air Brakes, and Combination Vehicles — the core tests every CDL applicant needs • Full narration of every lesson, not just summaries • Real practice exams matched to actual DMV question counts and passing scores (50 questions/80% for General Knowledge, 25/80% for Air Brakes, 20/80% for Combination Vehicles) • Unlimited practice quizzes with instant feedback and explanations • Missed-question review that links straight back to the lesson that covers it • Progress tracking across every topic, so you know what's actually ready • Class B and C drivers can turn off Air Brakes and Combination Vehicles if they don't apply STUDY YOUR WAY Read at your own pace, or switch to listener mode and let CDL Audible narrate while you drive, walk, or wait. Adjustable playback speed, lock-screen controls, and background playback mean the lesson keeps going even when your phone doesn't have your full attention. NO SIGNAL, NO PROBLEM Every lesson and all nine hours of narration are built into the app — nothing to download, no account to make, and no connection needed. Made for studying where cell service doesn't reach. FREE TO START The app is free, and it opens with a 10-minute trial of everything, no card needed.
