What the app looks like
Why our students pass
Based on the official CDL Manual (FMCSA model) — the same book the real test is based on.
Regulatory, warning, construction and truck-specific signs — the full set you can be tested on, plus the ones you meet on the road every day. Drill them until you recognize each one instantly.
Official federal-standard vector artwork — the signs look exactly like on the road. Exam-required signs are marked EXAM
Not just right or wrong — a clear explanation of why, so the rule sticks instead of being memorized and forgotten.
A single file that opens in any browser on your phone, tablet or computer. Study in your truck, at the parking lot, no internet needed.
Per-section and overall counters, training and exam modes, go back to previous questions, reset progress.
Three tests, exactly like the DMV gives them — General Knowledge, Air Brakes, Combination Vehicles. Same 80% federal passing score, same PASS/FAIL. You walk in already knowing how it runs.
40 key trucking terms with instant search, plus an interactive RODS logbook trainer (duty status, Personal Conveyance, Yard Move).
The core CDL theory follows one national FMCSA standard, so the same material is on the test wherever you sit it. Pick your state and the app names the agency that issues your CDL there, and reminds you that a state can vary the number of questions and add a few local ones — so check its own manual before test day.
15 sections — everything on the test
Plus two hands-on trainers that aren't question sets — a paper Daily Log Book and a real ELD simulator — and a trucking terms glossary.

FAQ
They are based on the official CDL Manual (FMCSA) — the source the real exam is built from. The English wording is always shown.
No. One purchase — yours forever, updates are free.
Mostly, yes. The core CDL knowledge (FMCSA's Model CDL Manual) is the same nationwide, but some states add their own rules — always check your state's current CDL manual before the exam. The app also has a state selector covering all 50 states and DC: choose yours and it shows which agency issues the CDL there, plus a note on what your state can vary. That information reflects the situation as of the app's release.
Yes — official MUTCD/FHWA artwork (the U.S. federal standard), the same drawings used on American road signs.
Every question is unique and based on the official FMCSA CDL Manual — we don't pad the bank with repetitive rephrasings just to inflate the count.
