If your career has been limited in the past by your inability to drive a commercial vehicle with air brakes, then it’s time to change that. This practice exam will help you prepare to get the air brakes restriction removed from your CDL or help you prepare to take the exam for a CDL without the air brakes restriction. These 30 multiple-choice questions were written with information directly from the North Carolina Commercial Driver’s Manual, and feature topics that the manual highlights as “need to know” for your air brake exam. By taking the exam as often as necessary until you are comfortable, and reading each question’s explanation so you fully understand the subject, you should be ready to handle the real CDL air brakes exam with ease. So good luck now, and on your future CDL air brakes exam!
