ID CDL Air Brakes “Endorsement” Practice Test 2 2025

Don’t let an air brake restriction on your Idaho Commercial Driver’s License (CDL) prevent you from pursuing great driving opportunities with companies such as Simplot! Most high-weight vehicles, such as semi-trucks and full-size buses, are equipped with air brakes, and you must know how to operate them to qualify for many commercial driving jobs. Air brakes are an essential safety feature that allows you to slow down while navigating sharp turns and making complete stops in heavily congested traffic. Without an extensive knowledge of air brake systems, you are needlessly placing yourself in potentially harmful situations and limiting your employment prospects. However, the process to remove the air brake restriction doesn’t need to be complicated once you’ve obtained sufficient training.

Our Idaho DMV CDL air brake “endorsement” practice test permits you to take advantage of a superior instruction method that other traditional study resources lack. Removing the air brake restriction requires you to pass a skills test in an air brake-equipped vehicle (including an air brake inspection) and an official air brakes knowledge test. The practice test is expertly designed to help you correctly answer the minimum required 80% of the 25 questions on the official knowledge test to pass. With its interactive capability, the practice test uses 30 questions to assess your proficiency level in real time and direct you to the information you must learn to improve. This approach provides you with a blueprint of your path to success. You will experience an expedited learning process that boosts your confidence and makes it possible to pass the official knowledge test on your first attempt.

This Idaho DMV CDL air brake “endorsement” practice test will ignite your excitement by easily eliminating your most difficult learning obstacles. Traditional study resources, like a study guide, make this task seem nearly impossible. Study guides make learning more complicated because they train you to memorize the answers to the questions without helping you correct the questions you get wrong. This approach limits you to learning surface knowledge that will not fully prepare you to react in response to changing driving conditions. In comparison, the practice test makes the information you need to better understand air brake systems readily available. If you submit an incorrect answer, the practice test provides a detailed explanation of the correct one. The information provided is taken directly from the most recent Idaho DMV CDL manual (Idaho CDL Handbook 2025) and is up to date as of September 2025. You can depend on this information to be accurate because it is taken from the most authoritative source. Based on the teachings of the practice test, you will confidently apply the information learned to various driving scenarios. The practice test will prepare you for better driving opportunities with an enhanced skill set.
