NE CDL Air Brakes “Endorsement” Practice Test 2 2025

By removing the “L” restriction from your Nebraska DMV Commercial Driver’s License (CDL), you will open the door to more driving opportunities. The “L” restriction prohibits you from operating vehicles equipped with air brakes, including most semi-trucks, tractor-trailers, and full-size buses. Potential employers, such as Lincoln Trucking and Omaha Metro Transit, are more likely to pass on drivers with an “L” restriction, disqualifying them from driving air brake-equipped vehicles. More braking force is required to navigate sharp turns and come to a complete stop in heavy traffic while transporting heavily weighted loads. Air brakes allow you to adjust your speed for these situations. With sufficient training, you can learn to operate air brakes, preserve your safety, and become more employable.

Our Nebraska DMV CDL air brake “endorsement” practice test streamlines the learning process by addressing your specific learning obstacles. Until you pass a skills test in a vehicle with air brakes (including conducting an inspection of the air brakes) and pass an official Air Brakes knowledge test, the air brake restriction will remain on your license. You must correctly answer at least 80% of the 25 questions on the official knowledge test to pass.

This Nebraska DMV CDL air brake “endorsement” practice test lays the foundation for you to build your knowledge of air brake systems. The practice test mimics the official knowledge test and contains 30 questions similar to the ones you may see on it. You can depend on the practice test to train you with reliable information in a format best suited to enhancing your knowledge.

The practice test is based on the most recent Nebraska DMV CDL manual (Nebraska CDL Handbook 2025) and is up to date as of October 2025. The CDL manual is the most authoritative source available, and the practice test uses the information it contains to fill your knowledge gaps. If you submit an incorrect answer, the practice test will provide a detailed explanation of the correct one using information from the CDL manual and show you how to apply it to various driving scenarios.

If you were to rely on traditional study methods, your learning experience would be more complicated and produce inferior results compared to the practice test. Instead of assisting you in absorbing essential information about air brake operations, traditional study methods focus on merely memorizing the answers to the questions without providing the information to correct your misunderstandings. The practice test provides the information you need and boosts your confidence to pass the official knowledge test on your first attempt.
