Frequently asked questions
- How many questions are on the real CDL tests?
- It varies by state, but the General Knowledge test is typically around 50 questions, Air Brakes around 25, and Combination Vehicles around 20. Our Exam mode mirrors those lengths and times you accordingly.
- Are these CDL practice tests really free?
- Yes — completely free, with no login, no paywall, and unlimited retakes. We make money from optional school and carrier referrals, never from charging you to study.
- What score do I need to pass?
- Most states require 80% to pass each CDL knowledge test, so that's the pass line we use. Our Practice and Exam modes score you against it and show exactly which topics to review.
- Where do the questions come from?
- Every question is written from the official CDL manual and checked by a human against the cited page before it goes live. We show you the manual section and page behind each answer — we never invent questions or use AI filler.
- Which states do these cover?
- The questions come from the AAMVA model CDL manual that most states use, so the General Knowledge material applies nationwide. For state-specific details, use your state's practice test — for example, the Ohio CDL practice test.
