CDL permit practice test: Class A & B, HazMat, Air Brakes. No subscription.
CDL Permit Ready is an independent study app made by SimpleDuo. It is not affiliated with, endorsed by, or sponsored by the FMCSA, the U.S. Department of Transportation, or any state driver licensing agency. It is study material, not driving instruction, and it does not issue permits or licenses. OFFICIAL SOURCES Every question in this app is written from, and cited to, the official public documents below. Read them yourself — the full list with direct links is at https://cdl.simpleduo.com/sources • 49 CFR Part 383 — CDL standards and requirements https://www.ecfr.gov/current/title-49/part-383 • 49 CFR Part 393 — parts and accessories for safe operation https://www.ecfr.gov/current/title-49/part-393 • Texas DPS — Commercial Motor Vehicle Driver Handbook (DL-7C) https://www.dps.texas.gov/internetforms/Forms/DL-7C.pdf One purchase, $19.99, and it's yours — no subscription to cancel, no ads, no account. Try it first: 10 free questions a day, plus one full General Knowledge mock exam. Your first driving paycheck is waiting on the CLP knowledge test. CDL Permit Ready is CDL permit practice test prep for Class A and Class B: ten minutes a day, and a readiness score that tells you the day you're actually safe to book. WHAT CHANGES FOR YOU • You stop guessing. Readiness models what you'll still remember on exam day — not how many questions you've clicked through. When it reads 90%, book. • You stop wasting evenings. Spaced review brings each miss back right before you'd forget it, and skips what you already know. A question counts as mastered only once you've had it right twice, days apart. • You walk in having already passed. The CLP is separate exams, and the mocks mirror that: General Knowledge (50 questions, 60 minutes), Air Brakes (25) and Combination Vehicles (20), each timed and scored at the real 80% pass line. Back-to-back mocks draw different questions. • Every miss becomes a lesson. After each mock, go through every question you got wrong — your pick, the right answer, why, and the manual section it comes from. ENDORSEMENTS HazMat (H), Tanker (N), Passenger (P), School Bus (S), and Doubles & Triples (T) — each its own timed mock, the way each is its own test at the DMV. Add only the ones you're testing for; the rest stay out of your plan and your readiness score. SPANISH, DONE HONESTLY Turn on "Ayuda en español" and every question, every answer choice, and every explanation shows Spanish under the English. The real test is in English — the Spanish is there to make sure you understand it, never to replace it. Terminology is checked against the official Spanish-language CDL handbooks (perno maestro, mandíbulas, frenos de aire), not machine-translated on the fly. The app's menus are in English. WHY YOU CAN TRUST THE ANSWERS 645 questions, each with a plain-English explanation and a citation to the CDL manual section or federal rule it came from, so you can check our work against the source. Every numeric claim — air-pressure limits, tread depths, BAC, permit validity — is machine-traced to the official texts before it ships. YOUR STATE The core rules are federal and the bank covers them in depth. Texas, California, Florida, Georgia, Illinois, Pennsylvania, North Carolina and Ohio get state-specific questions folded into your plan, with more states on the way. WHAT WE WON'T CLAIM No pass rate, no "3× faster", no "exact DMV questions". We have no study on this app that would let us say those things. What we stand behind: the content is checked against primary sources and cited, and the plan doesn't spend your time on questions you already know. PRIVATE BY DEFAULT No sign-in, no analytics, no advertising SDKs. Your progress stays on your phone and travels to a new one through your own Google backup. FOUND A WRONG ANSWER? Every question has a flag button, and reports go to the front of the queue. Privacy: https://cdl.simpleduo.com/privacy Terms: https://cdl.simpleduo.com/terms
