CDL Wizard

Study smarter and pass your CDL written knowledge test the first time. CDL Wizard turns the official commercial driver's license material into focused practice you can do anywhere — no account, no internet required.

Built for real test prep:
• State-specific questions — pick your testing state and study the exact material it uses
• Study Mode — learn in focused groups of 10; master one set before unlocking the next
• Exam Mode — full-length practice tests you can skip and return to, just like the real DMV exam
• Review Missed — every question you miss goes into a list you can re-drill until it sticks
• Readiness tracking — see your best score per category and know when you're truly ready (80%+ is passing)
• Plain-English explanations on every question, so you learn the "why," not just the answer

Covers every CDL knowledge test and endorsement:
• General Knowledge
• Air Brakes
• Combination Vehicles
• Hazardous Materials (Hazmat)
• Tanker
• Doubles & Triples
• Passenger
• School Bus
• Pre-Trip Inspection — photo flashcards and study for the parts you'll identify

Why drivers choose CDL Wizard:

• Clean, distraction-free, built to get you passing fast
