Ohio CDL General Knowledge Practice Test 1: what to expect and what trips drivers up

Start your commercial license here. This free Ohio CDL practice test is the flagship general knowledge rehearsal for 2026, built to mirror the real written exam the Ohio BMV gives when you apply for your Commercial Learner's Permit. Because that written test is what earns your CLP, an Ohio CDL permit test and this Ohio CDL practice test are the same exam under two names. Take it online as many times as you like.

How many questions are on the Ohio CDL general knowledge test? There are 50, and you need 80 percent, which is 40 correct, to pass. The questions span pre-trip inspection, vehicle control, shifting, space and speed management, and handling hazards. Whether you want a free CDL practice test, a DMV CDL practice test feel, or a CDL practice test online, this page delivers it for Class A, B, and C applicants alike, since your class comes from the skills test and the truck you drive.

Ohio runs on making things and moving them, with freight pouring across I-70, I-71, and the I-80 Ohio Turnpike between factories and distribution centers. That is why this Ohio CDL practice test doubles as a foundation for the Combination and Air Brakes exams. Keep taking it until 40 of 50 is routine, lean on the Ohio CDL Manual, then book with the Ohio BMV.

Keep going:

Every question traces back to the Ohio CDL Manual - skim the right-of-way and signs chapters before your retake.
