CDL Prep Test 2025 | EZ Prep

**Pass the CDL Exam Without Jackknifing Your Sanity**
You’ve learned how to shift, inspect, load, brake, and somehow stay calm while merging an 80-foot rig into rush hour traffic. Now it’s time to get certified. EZ Prep’s CDL Study App helps you pass the CDL exam without flipping out like an unsecured trailer on a mountain curve.
Whether you’re on break, stuck at the yard, or soaking in the bath trying to forget pre-trip checklists, EZ Prep goes wherever you go. The app works offline, adapts to your skill level, and actually helps you remember what matters.
Written by licensed CDL drivers who’ve been through the exam and lived to haul another day, EZ Prep doesn’t give you outdated flashcards or recycled content. It builds a personalized study plan that gets harder as you get better, so you’re always learning, never coasting.
Try it free with a limited version of the app. When you're ready, upgrade to unlock Bookmarks, Missed Questions, and our full Exam Simulator that mimics the real test, minus the sweaty palms and DMV carpet smell.
