Pass your CDL knowledge test on the first try — and know you are ready before you book it. All 1,495 practice questions here are written from official state CDL handbooks, and every answer names the handbook section it came from. WHY THIS ONE IS DIFFERENT • Every answer cites its source. Miss a question and you get why your choice was wrong, why the right one is right, and the exact handbook section — so you can go check it yourself. • Your state's answer, not a generic one. State handbooks disagree with each other: the low air pressure warning is 55 psi in some manuals and 60 psi in others. We track 105 of these differences per state instead of shipping one national question bank. • A readiness score that will not flatter you. It weighs how much material you have covered, your accuracy, how consistent you are and how recent your practice is — then estimates your chance of passing. Five right in a row does not make it move much, because it should not. EVERY SUBJECT, EVERY ENDORSEMENT • General Knowledge — required for every applicant • Air Brakes — the section most applicants fail first • Combination Vehicles — Class A tractor-trailer • Pre-Trip Inspection — what the examiner wants pointed at, in order • HazMat (H) — placarding, shipping papers, the segregation table • Tank Vehicles (N) — surge, baffles, outage • Passenger Transport (P) — loading, standee line, emergency exits • School Bus (S) — danger zones, loading, railroad crossings • Doubles & Triples (T) — coupling order, converter dollies, trailer sway Class A, Class B, Class C and commercial learner's permit (CLP), for all 50 states and DC. STUDY THE WAY THE TEST WORKS • Practice by subject with the explanation right there • Exam Simulator that matches the real test's length and pass mark • Timed Drill for exam-day pacing • Daily Study — five questions rebuilt from what you keep missing • Missed Questions and bookmarks, so nothing you missed disappears • Flashcards for quick drills between sessions • Handbook Mode to read straight through, questions and answers together AI COACH Miss a question and the AI Coach explains it in plain language — why your answer was wrong, why the right one is right, and where the handbook says so. Ask a follow-up in your own words and it answers. Tap for a real-world example, something you would meet at a scale house or on a pre-trip. Tap again for a quick check on the same topic to see if it stuck. BUILT FOR LIFE ON THE ROAD • The question bank lives on your device. Study in the sleeper, in the yard, or anywhere with no signal. • Daily reminders at a time you choose • Progress synced across your devices • App interface in English or Spanish FREE, WITH AN OPTIONAL UPGRADE 888 questions across the four core subjects are free — no account, no card.
