Smart CDL

Study cards, practice quizzes, and full-length exams for the commercial driver license knowledge tests — built for your state, working entirely offline.

Study that works

• Study cards that condense your state's requirements down to what you actually need to know
• Short, focused quizzes for every topic — a few minutes at a time
• Full-length practice exams scored at the real 80% passing mark
• General Knowledge, Air Brakes, Combination Vehicles, and every endorsement

Learn from every mistake

• Wrong answers are explained on the spot, while the question is still fresh
• After each exam, step back through every question — your answer beside the correct one

Works offline

• The whole app runs on your device — study in the cab, at the dock, anywhere without internet
• Nothing to load and nothing to sync, so it is always ready when you are

Private by design

• No account, no sign-up, no ads
• No analytics, no tracking — the app collects nothing about you
• Your progress stays on your device, under your control
