LA CDL Air Brakes Practice Test 2 2025

The “L” air brake restriction on your Louisiana Commercial Driver’s License (CDL) disqualifies you from driving most semi-trucks, tractor-trailers, and full-size buses. You won’t be able to pursue many job opportunities with companies such as Turner Industries and Boasso Global to maximize the benefits of having a CDL. Air brakes let you regulate your speed while reacting to road conditions. Since air-brake-equipped vehicles typically transport heavily weighted loads, more braking force is required to slow down around sharp curves and come to a complete stop in heavy traffic. Your ability to operate air brakes is crucial to preventing injury or damage to people and property. Removing the “L” restriction begins with getting the appropriate training, and you will find one resource that stands out from the rest.

Our Louisiana OMV CDL air brake “endorsement” practice test is designed to help you strategically overcome your learning obstacles. The process of removing the air brake restriction involves your ability to pass a skills test in a vehicle with air brakes (including inspecting the air brakes) and an official Air Brakes knowledge test. The practice test gives you an interactive resource for comprehensive instruction, helping you better understand air brake systems and prepare for the challenges of the official knowledge test. You must answer 80% of the 25 questions on the official knowledge test to receive a passing score. The practice test includes 30 questions similar to those on the official knowledge test to help you achieve this score in an effective and time-efficient manner.

This Louisiana OMV CDL air brake “endorsement” practice test provides reliable and authoritative information to expand your knowledge. The practice test is based on the most recent Louisiana OMV CDL manual (Louisiana CDL Handbook 2025) and up to date as of August 2025. While you may have knowledge gaps in your understanding of air brake operation, the practice test works to fill them with information taken directly from the CDL manual. If you submit an incorrect answer, the practice test will provide the information you must know to correct it. This approach targets your specific misunderstandings and speeds up the learning process.

Unlike the practice test, traditional study methods are more one-dimensional and can leave you stuck while searching for information to correct your wrong answers. Traditional study methods train you to memorize the answers to the questions without providing feedback to help you correct the questions you get wrong. The practice test shows you how to apply its teachings to various driving scenarios, boosts your confidence, and increases your chances of passing the official knowledge test on your first attempt.
