Free Ohio CDL Permit Practice Test: General Knowledge 2025

Have you been reading the official Ohio Commercial Driver License Manual (Ohio CDL Handbook 2025) because you need to pass the official General Knowledge test on commercial driving? Concerned that you still may not pass the test without some additional help? No problem! You’ve certainly come to the right place. You’re not the only one in this situation by any means. That’s why so many other aspiring commercial drivers have decided to supplement their reading of the manual with other study tools, such as the ones we offer.

This free Ohio CDL permit practice test is based on the official manual, just like the official General Knowledge test. The practice test is up to date as of September, 2025. Practicing with it will make all the material covered by the test questions easier to remember. To make your learning easier, each of the 50 practice questions comes with a helpful hint and an explanation of the correct answer. The practice questions on this test will assess your knowledge of such topics as basic vehicle maneuvers, cargo management, following distance, stopping distance, and vehicle components. Stuck on a puzzling question? Our automated assistant can give you a hint. Still got the question wrong? The assistant can give you an explanation of the correct answer.

Besides passing the General Knowledge test, you must meet some other requirements at this stage, such as completing a medical examination and receiving your Medical Examiner’s Certificate proving that you completed it. Once you obtain a Commercial Learner’s Permit (CLP), you can start practicing for the skills test. Passing the skills test is a necessary step toward obtaining a Commercial Driver’s License (CDL). The skills test consists of three parts: basic vehicle maneuvers (such as backing), a pre-trip inspection of the vehicle, and a road test.

Once you hold a CDL, you can profit from all the commercial driving opportunities Ohio has to offer. Ohio is the third-largest manufacturing state (behind California and Texas), with over 12,000 manufacturers, creating a demand for truck drivers to carry their products. Ohio also employs truck drivers to transport products from its large agricultural sector. As befits Ohio’s role as a major Midwest commerce hub, it is served by such important truck routes as Interstate 70 (which runs from Utah through Columbus and on to Maryland), Interstate 71 (which starts in Kentucky and connects Columbus, Cincinnati, and Cleveland), and Interstate 75 (which runs from northern Michigan through Toledo, Dayton, and Cincinnati and on to Florida).

This test is great whether you’re applying for your CDL for the first time or renewing. Of course, passing this practice test is only a first step. The real goal is to become a safe and proficient commercial driver on Ohio’s roads. Go through the exam at your pace, learning from every question, and then get ready to take your place among the ranks of Ohio’s professional drivers.

Good luck, and drive safe out there!
