Free Wisconsin CDL Air Brakes Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 WI commercial driver's license manual
  • Updated for March 2025

The best way to stand out from the pack in Wisconsin as a truck driver is to have as many options as possible, when it comes to your qualifications and skills, and that means being able to drive a vehicle with air brakes. This exam features 30 multiple-choice questions based on the information that you’ve already studied in the Wisconsin Commercial Driver’s Manual, which is noted in the manual as possibly appearing on your exam. The more often you practice, by answering questions and reading each question’s accompanying explanation, the more comfortable you will be with air brake topics and information, and the more likely to pass your CDL air brake exam with flying colors. Then you’ll be on your way to success as you can drive a wider range of commercial vehicles. So, start practicing today, come back as often as possible, and good luck both now, and on your real Wisconsin air brake exam in the future!
