WV CDL Air Brakes “Endorsement” Practice Test 2 2025

An extensive knowledge of air brake operations will serve you well in your pursuit of the best driving opportunities. Air brakes are a vital safety feature in most semi-trucks and full-size buses that allow you to reduce your speed and come to a complete stop while transporting heavy loads. An “L” restriction on your West Virginia Commercial Driver’s License (CDL) prohibits driving an air brake-equipped vehicle and limits your driving opportunities. Potential employers, such as DeBarr Trucking and Mountain Line Transit, value the safety of drivers, passengers, and cargo, and knowing how to use air brakes is an essential part of ensuring it. Your ability to regulate your speed is crucial in navigating rapidly changing road conditions (such as dense fog and heavy traffic) and requires thorough training.

Our West Virginia DMV CDL air brake “endorsement” practice test helps you establish a solid foundation to expand your knowledge of air brake operations. Successful removal of the “L” restriction from your CDL requires you to exhibit your ability to drive an air brake-equipped vehicle, inspect the air brake system, and pass an official Air Brakes Knowledge Test. You must correctly answer a minimum of 80% of the 25 questions on the official knowledge test to earn a passing score. The practice test is expertly designed to help you develop the skills to satisfy these requirements. Using 30 questions, the practice test provides a real-time evaluation of your proficiency and identifies the information you must study more to become an air brakes expert.

Effective learning begins with studying reliable information, and this CDL air brake “endorsement” practice test is unmatched in its ability to provide it. The practice test is based on the most recent West Virginia DMV CDL manual (West Virginia CDL Handbook 2025) and is up to date as of September 2025. If you submit an incorrect answer, you’ll receive feedback from the practice test with a full explanation of the correct one. This explanation is written using information taken directly from the CDL manual. Since the CDL manual is the most authoritative source available, you can be confident in applying it to various driving scenarios on the official knowledge test.

Unlike the practice test, traditional study methods use an approach to learning that can make the learning process more complicated. Traditional study methods train you to memorize the answers to the questions and depend on you to conduct your own research for information to correct your wrong answers. This approach cannot address your specific learning obstacles and makes it more challenging to develop an extensive knowledge of air brake systems. In comparison, the practice test gives you immediate access to the information that eliminates your misunderstandings. The practice test simplifies your path to success and increases your chances of passing the official knowledge test on the first try.
