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.\n\nIn 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.   \n\nOne 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.","facts":{"developer_id":1083859790,"developer_url":"http://cdlstudybuddy.com","first_released":"2016-02-18T18:00:40Z","support_url":"http://cdlstudybuddy.com/contact/","privacy_url":"http://m.cdlstudybuddy.com/","website_url":"http://cdlstudybuddy.com/","app_version":"1.0","release_notes":null,"rating_current_version":3.34483,"rating_count_current_version":29,"star_counts":[8,2,3,4,12],"genres":["Education","Reference"],"languages":["EN"],"content_advisories":null,"device_families":["iphone","ipad","ipod"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-13T13:30:13.472Z","catalog_read_at":"2026-11-03T16:00:12.945Z","reviews_checked_at":null,"summary_written_at":"2026-11-03T14:28:12.740Z","placed_at":"2026-11-03T15:32:12.983Z","scored_at":"2026-11-14T15:06:12.900Z"},"editorial":{"one_liner":"Free Education app with over 1,000 CDL test questions, state CDL handbooks in PDF and audio, and inspection.","what_is":"CDL Study Buddy is a free study app for commercial driver's license (CDL) written tests, made by a developer who says they have driven trucks for over 20 years.
