About the Ohio General Knowledge Test
Topics Covered
- ✓Vehicle inspection procedures — Ohio BMV examiners watch your pre-trip like a hawk. They want the full walk-around, brake check, and light test.
- ✓Basic control and backing — You'll face tight docks at Ohio warehouses and distribution centers. Straight-line backing and offset backing are tested hard.
- ✓Shifting and gear selection — The hills on I-77 and US-33 mean you need to know when to downshift before a grade, not halfway up.

The Ohio CDL manual is your starting point, but don't just read it — apply it to real Ohio roads. When it talks about braking on downgrades, picture coming down the hill on I-77 near Marietta. When it covers winter driving, think about the lake-effect bands off Lake Erie that dump a foot of snow in an hour on I-90 east of Cleveland. That mental connection helps the answers stick.
Ohio BMV examiners love questions about inspection procedures. They'll ask you the exact order of checking air brakes, and they expect you to know how much air loss is acceptable per minute. Memorize the numbers: 3 psi loss per minute for a combination vehicle, 2 psi for straight trucks. Also, Ohio requires you to know the state's specific chain laws — when chains are mandatory on certain routes during winter storms.
Take practice tests like this one to get used to the timing. 50 questions in 60 minutes gives you just over a minute per question. If you're stuck on a question, mark it and move on. You can come back. The real test doesn't let you skip, but our simulator does — use that feature to manage your time.
Ohio's CDL testing is managed by the Ohio Bureau of Motor Vehicles (BMV). You can take the General Knowledge test at any BMV deputy registrar location that offers CDL services. Major testing sites include the Columbus BMV on Morse Road, the Cleveland West Side location, and the Cincinnati Norwood office. Appointments are strongly recommended — walk-ins face long waits, especially in the summer.
The fee for the written test is included in your CDL permit application, which costs $25 as of 2026. You'll need to bring your valid Ohio driver's license, proof of Social Security number, and a current Medical Examiner's Certificate (DOT physical). If you're under 21, you also need to complete a driver training course approved by the Ohio BMV.
Ohio does not allow you to take the General Knowledge test online — you must appear in person. The test is available in English and Spanish. If you fail, you can retake it the next business day. There's no limit on retakes, but you pay the $25 application fee each time you renew your permit.
About the Ohio General Knowledge Test
The General Knowledge test is your first step toward any Ohio CDL — Class A, B, or C. It covers vehicle inspection, basic control, shifting, backing, and the rules of the road that apply to all commercial vehicles. You won't get behind the wheel until you pass this written exam.
Ohio follows federal standards, but the state's geography and weather make some topics more important here. You'll need to know how to handle the lake-effect snow that piles up on I-90 east of Cleveland, and the steep grades on I-77 through the Appalachians. The BMV also expects you to understand Ohio's specific traffic laws for trucks, like the 55 mph speed limit on rural interstates and the chain-up requirements during winter storms.
This practice test follows the exact format of the real thing: 50 multiple-choice questions, 60 minutes, 80% to pass. The questions are pulled from the Ohio CDL manual and reflect what BMV examiners actually emphasize. Don't waste time studying generic national material — focus on what Ohio tests.
