## What is CDL Permit Prep?

Study for your commercial driver's license the way the real CDL exam actually asks it.

CDL Prep gives you 1,300+ practice questions drawn from the federal CDL standards your state's written test is built on — General Knowledge, Air Brakes, Combination Vehicles, Hazmat, Tanker, Doubles/Triples, Passenger, School Bus, Hours of Service, and Pre-Trip Inspection. Every question comes with a plain-language explanation, so a wrong answer teaches you something instead of just costing you a point.

EVERY TEST AND ENDORSEMENT
• General Knowledge — the core written test every applicant takes
• Air Brakes — the endorsement most applicants fail first
• Combination Vehicles — coupling, uncoupling, trailer handling
• Hazmat — placards, loading rules, security plans
• Tanker and Doubles/Triples
• Passenger and School Bus
• Hours of Service, weight distribution, and emergency procedures
• Pre-Trip Inspection, laid out the way an examiner asks for it

CLASS A AND CLASS B
Pick your license class and the app narrows the bank to what you actually need. No wading through school bus rules when you are studying for a Class A over-the-road job.

BUILT TO FIND YOUR WEAK SPOTS
Missed questions collect in one place so you can drill them again instead of retaking whole tests. Progress is tracked per category, so you can see at a glance that your air brakes score is holding you back before test day tells you.

REAL EXAM CONDITIONS
Practice exams match the question count and the 80% pass mark your state's CDL knowledge test is scored against, so the first time you sit the real one it does not feel new.

PRE-TRIP INSPECTION, OUT LOUD
The pre-trip is a recitation, not a multiple-choice quiz. The app walks the inspection point by point and lets you practice speaking it, because that is how it is scored.

STUDY ANYWHERE
The full question bank works offline. Truck stop, sleeper berth, waiting room, no signal needed.

YOUR STATE'S EXAM FORMAT
Commercial licensing is federal at the core and state-specific at the edges. Choose your state and practice exams follow that state's published format — how many questions each class is asked, and the scoring it is marked against, each cited to the state's own source.

WHO THIS IS FOR
• First-time applicants going for a CLP or CDL
• Drivers adding an endorsement to a license they already hold
• Drivers upgrading Class B to Class A
• Anyone who failed the written test and wants the second attempt to be the last one

No account required to start studying. No ads interrupting a practice exam.

Practice is not the exam. Always check your state's current commercial driver handbook for the rules that apply to you on test day. This app is not affiliated with any state licensing agency or the FMCSA.
