Questions drivers ask
Is this the real CDL test?
No. The questions are original study questions written from the AAMVA model CDL manual, with the page in your state's manual cited. Your state's test may differ in length; the pass mark is 80% almost everywhere.
Which tests and endorsements are covered?
General Knowledge, Air Brakes and Combination Vehicles, plus the HazMat (H), Tank (N), Doubles and Triples (T), Passenger (P) and School Bus (S) endorsements. X is Tank plus HazMat.
How does CDL Coach cover all 50 states?
Our current source catalog classifies 47 state CDL manuals as AAMVA-based, so much of the tested knowledge is shared. Georgia and Illinois are classified outside that group; Arizona is not yet classified. Choose any of the 50 U.S. states and CDL Coach links your study path to that state's manual.
Do I need to be online?
No. Once installed, practice works offline. Manual links open the official PDF when you are back online.
What does "ready" mean?
Eighty percent of a test's questions mastered without a hint, nothing left in your review list, and the exam simulator passed three times in a row. The app says it per test.
Does the app cover the skills test?
No. CDL Coach prepares you for the written knowledge tests. The vehicle inspection, basic control and road tests are done in a truck with an examiner; the app's study notes cover what the inspection test asks for.
