Streamline daily tracking and management with HaulPass CDL 学科対策. Core features work offline, no account required.
Get ready for your CDL knowledge tests with HaulPass - every subject is open from the first launch.
Most CDL prep apps put the questions you actually need behind a subscription, for a test you take once. HaulPass locks nothing: all 8 subjects, every question, every explanation and unlimited practice exams are available from the start. A single banner at the bottom of the screen is what pays for the app. If you would rather not see it, there is one optional purchase that hides the banner - it does not unlock anything, because nothing is locked.
ALL 8 KNOWLEDGE TEST SUBJECTS
- General Knowledge
- Air Brakes
- Combination Vehicles
- Hazardous Materials
- Tanker Vehicles
- Doubles & Triples
- Passenger Vehicles
- School Bus
STUDY TOOLS THAT WORK
- 740+ original practice questions written from publicly available state CDL manuals
- Every question includes a clear, human-written explanation - understand why, not just what
- Missed questions collect automatically; answer them right twice in a row to clear them
- Timed exam simulator that follows your state's exam profile (question count and passing score; most states use the standard FMCSA pattern)
- Retake the exam as often as you like
- Progress, accuracy and exam history for every subject
- Pick your state (all 50 + DC) or use the general FMCSA profile
- Interface in English, Japanese and Simplified Chinese
NO PAYWALL, NO SUBSCRIPTION
- Nothing is locked. There is no study quota and no "pro" tier.
- One optional in-app purchase removes the bottom banner. That is all it does.
PRIVACY
Your progress, missed questions and exam history stay on your device. No account, no sign-in, and the app never asks for tracking permission. Studying works with no connection at all - only the bottom banner needs the internet.
HaulPass is an independent study aid based on publicly available state CDL manuals. It is not affiliated with any DMV or FMCSA, and it is not an ELDT training provider. Passing this app's practice exams does not guarantee passing your official test.
