“The House That Rockne Built” is revered in athletic circles, but an Air Brakes restriction on your Indiana commercial driver’s license (CDL) may get you noticed for the wrong reasons. An air brakes restriction on your CDL limits your driving opportunities and earnings potential. Our Air Brakes practice test series can equip you with the skills to reverse such fortunes. With this third free Indiana BMV CDL Air Brakes practice test, you’ll expand the skills you acquired through your Entry-Level Driver’s Training (ELDT) and prepare yourself to explore a wider range of employment options. If you feel air brakes are too complicated to understand, the practice test can change your perspective.
Bringing together reliable information and an innovative approach to learning, our Indiana BMV CDL Air Brakes practice test ignites your learning process. You must be able to perform a physical inspection of the air brake system and pass an official Air Brakes knowledge test to remove the restriction from your CDL. The official knowledge test requires you to correctly answer a minimum of 80% of its 25 questions to pass. Using 30 questions resembling those on the official knowledge test, the practice test reveals the information you find most confusing and provides critical information to gain a better understanding of it.

This Indiana BMV CDL Air Brakes practice test is designed to use accurate information to address and help you overcome your specific learning obstacles. The practice test is a stress-free learning environment designed to provide helpful feedback on any incorrect answer you submit. You won’t need to consult additional resources to find the required information because the practice test gives an in-depth explanation of the correct answer in an easily understood language. This approach differs from study methods you likely used in the past, such as a study guide, which trained you to memorize the answers to the questions. You can trust the information the practice test provides because it is taken directly from the most recent Indiana BMV CDL manual (Indiana CDL Handbook 2026) and is up to date as of January 2026. Using the information from this authoritative source, you can be confident in your ability to become an expert in air brake operations. You’ll be able to successfully apply what you have learned to various driving scenarios on the official knowledge test. Best of all, you will likely pass the official knowledge test on your first try.
