Pass your CDL knowledge test on the first try — and know you are ready before you book it.
All 2,053 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: why your choice was wrong, why the right one is right, and the exact handbook section, so you can check it yourself.
• Your state's answer, not a generic one. State handbooks disagree: the low air pressure warning is 55 psi in some manuals and 60 psi in others. 649 questions here change with your state instead of one national bank.
• A readiness score that will not flatter you. It weighs how much you have covered, your accuracy, consistency and how recent your practice is — then estimates your chance of passing. Five right in a row does not move it 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
• HazMat (H) — placarding, shipping papers, segregation
• Tank Vehicles (N) — surge, baffles, outage
• Passenger Transport (P) — loading, standee line, exits
• School Bus (S) — danger zones, loading, railroad crossings
• Doubles & Triples (T) — coupling, converter dollies, sway
Class A, B and C, and the learner's permit (CLP), in all 50 states and DC.
