Frequently asked questions
- Is this the official Ohio CDL test?

- What's the passing score on the Ohio CDL knowledge test?
- You need 80% to pass each Ohio CDL knowledge test, which is the pass line our Practice and Exam modes use.
- Where do the Ohio questions come from?
- Every Ohio question is written from the Ohio CDL Manual (BMV form HSY 7605, the AAMVA 2025 modernized manual the state distributes) and hand-checked against the cited page before it goes live. We show the manual section and page behind each answer.
- 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.

- 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.
