KS CDL Air Brakes “Endorsement” Practice Test 2 2025

You may already be enjoying your “Home on the Range,” but the “L” restriction on your Kansas Commercial Driver’s License (CDL) is limiting your driving opportunities. The “L” restriction prohibits you from operating air-brake-equipped vehicles. Sharp turns, adverse weather, and heavily congested traffic call for you to regulate your speed to avoid accidents. Air brakes make it possible to safely navigate changing road situations that require you to slow down or come to a complete stop while transporting heavy loads. Semi-trucks and full-size buses are among the vehicle classes equipped with air brakes. If you’re planning to operate such vehicles, you must obtain the necessary training to become an air brake-qualified driver.

Our Kansas DMV CDL air brake “endorsement” practice test will thoroughly prepare you to remove the “L” restriction from your CDL. The process of removing the air brake restriction involves conducting a physical inspection of the system, driving a vehicle equipped with air brakes, and passing an official Air Brakes knowledge test. You must correctly answer at least 80% of the 25 questions on the official knowledge test to achieve a passing score. Using 30 questions like those on the official knowledge test, the practice test assesses your proficiency level and identifies the information you should better understand. You will be equipped with the information to develop an effective study plan to overcome your specific learning obstacles and meet the challenges of the official knowledge test.

This Kansas DMV CDL air brake “endorsement” practice test streamlines the learning process to help you rapidly establish a solid knowledge base. You will be provided with comprehensive instruction that motivates you to continue studying and inspires confidence in your ability to exhibit your skills. The practice test is based on the most recent Kansas DMV CDL manual (Kansas CDL Handbook 2025) and is up to date as of August 2025. The CDL manual is the most authoritative source available and provides the logic you can use to support your answers. If you get a question wrong, the practice test will provide a detailed explanation of the correct answer with information taken directly from the manual. The practice test effectively addresses your specific learning obstacles and makes the information needed to correct them conveniently available. If you have previously used more traditional study methods, you know they are unable to interact with you and provide additional instruction. Traditional study methods are focused on helping you memorize the answers to test questions and less concerned with providing relevant information to fully develop your skills. The practice test provides this information and helps you apply it to various driving scenarios. Using the practice test, you will gain an in-depth understanding of air brakes and increase your chances of passing the official knowledge test on your first attempt.
