Today, you will have an opportunity to not only become a safer commercial driver, but to also get a less restricted CDL in the state of Ohio. In order to have CDL without the air brakes restriction, you must correctly answer exam questions about air brakes. This 30-question practice exam, which is based closely on practice questions directly from the Ohio Commercial Driver License Handbook, will allow you become comfortable not only with the format of the exam (multiple-choice) and the subject matter, through answering questions and reading each explanation that comes with the questions. Soon, you will be able to receive the score that you want on your air brakes exam and you’ll be a safer, less limited Ohioan commercial driver, so good luck!
