Ready to put your new knowledge to the test? This Connecticut CDL Air Brakes Marathon is a massive study tool that contains a combination of all 183 questions that we have available for this CT endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Give it your best shot!

To fully understand the Air Brakes endorsement process and to master the material for the written exam, explore our detailed guides on the Air Brake endorsement and the Air Brakes written test.
