OH CDL General Knowledge Exam Simulator 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.
