Ready to assess your knowledge of air brakes? Take our free South Dakota CDL Air Brakes Practice Test to see if you have the depth of understanding to pass the real test and earn your endorsement. Just like the real test, our practice test contains 25 multiple choice questions drawn from the South Dakota CDL Handbook. What is a supply pressure gauge used for?
