The air brakes endorsement applies to applicants who wish to drive a vehicle with air brakes in Class A, B, or C CDL. To drive a vehicle with air brakes, you must pass the air brake component of the Connecticut CDL knowledge test. The CT CDL air brakes test consists of 25 questions, and you'll need at least 20 correct answers to pass (80%). The test covers the information found in the air brakes section of the Connecticut CDL Manual. Take this CT CDL practice test now to prepare for the actual air brakes test!

tire pressure is low.

All of the above.
