HaulPass: CDL Permit Test

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.
