Updated for April 2025

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.

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
