OH CDL General Knowledge Exam Simulator 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

The Ohio CDL General Knowledge (permit) test has 50 multiple-choice questions. You must answer all questions before the timer ends. Score 80% or higher to pass and make significant progress in the licensing process. Becoming a safe and responsible commercial driver in Ohio takes time and effort, but we’ll make it easier for you to increase your knowledge. With determination and perseverance, any goal is achievable. However, you should avoid rushing through your learning phase. It is impossible to learn the various aspects of commercial driving theory overnight, so we recommend dedicating several weeks to studying this subject.

As exam day approaches, some students experience severe anxiety that can hinder their performance. It is normal to feel nervous as you head to the BMV office, but you shouldn’t let those negative feelings control you. Build the confidence and knowledge necessary to pass the official exam on your first attempt by training with our Ohio CDL General Knowledge Exam Simulator. It is available 24/7 and can be accessed on any device with a browser and a stable internet connection. All 50 questions are based on the official Ohio commercial driver license manual (Ohio CDL Handbook 2025). If you are unfamiliar with this resource, please read its contents at least once. It contains crucial information every commercial driver should know, including traffic laws, safe driving practices, and pre-trip inspections.

To simulate the official testing experience as accurately as possible, you should avoid using external help when you train with our simulator. You must pass this test on your own, so you will not receive assistance. Although the test provides no feedback for the questions you get wrong, they will be automatically added to your personal Challenge Bank™. Please visit this section occasionally to learn from your mistakes and improve your knowledge before your next attempt. The more you train with our simulator, the better prepared you’ll be for the official exam.

Am currently working in fla.
I am currently working in fla. and with my new job I needed my hazmat and tanker endorsement so when I went home to visit I only had a week to get everything done including my tanker and hasmat. I got my tanker endorsement with no problem. that left me with the hazmat certification testing and background chk to do with only a few days left. thankfully I found this and did my certification and kept studying did the course and back ground chk and I went straight to the bmv feeling good I went in took the test I was done in less than 10 mins 100% I couldn't believe it every question was in program. finished my visit with my family with 3 days left and no stress. thank you I couldn't have passed it with out this program

Downloaded the program, I did the learning modules, and then.
I downloaded the program, I did the learning modules, and then did all the tests and everything, and I finished up today. As soon as they said that I was able to go to the DMV, I left my house, went and took my test, and passed it on the first try! All the questions that were on the program, the practice tests, all that stuff, they were all on there. It was only like maybe two questions that weren't on there, but I just skipped those and went ahead and kept answering all the questions that I knew, and I passed with a perfect explorer. First try. This program is awesome.

1 weekend, 3 endorsements, all aced.
Studied over the weekend to pass 3 cdl endorsements on Monday. The practice tests made the actual exam questions plenty familiar. The change in wording of the final exam Simulations from the practice ones helped me retain the information in different forms so that the real deal wouldn't fool me out of questions that I knew the answers to. All in all, I didn't het a perfect score but not a bad one either; passed them all at once.

Hazmat endorsement.
Brought the hazmat eldt and it was really helpful. Things I knew but it was also a lot of things I didn’t know. I’m prepared to take my knowledge test. Definitely will use again for future cdl class A endorsements. 5 stars
