CDL Audible
Narrated CDL Test Prep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Study for your CDL knowledge test hands-free. Every lesson narrated, real practice exams, and no signal needed — perfect for studying in the cab.
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. Reading the lessons, every quiz, and every practice exam stay free and unlimited after that, with no cap on retakes.
