Today, you will have an opportunity to become a safer commercial driver and get one step closer to a less restricted CDL in the state of Minnesota. In order to have CDL without an air brakes restriction, you must correctly answer exam questions about air brakes. This practice exam, based closely on questions directly from the Minnesota Commercial Driver’s Manual, will allow you become comfortable with both 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 Minnesotan commercial driver. Good luck!
