- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 NM commercial driver's license manual
- Triple-checked for accuracy
- Updated for August 2025
Commercial drivers need to be prepared for quickly changing road situations. They should have extensive knowledge of air brakes to stay safe and qualify for the best driving opportunities. Air brakes are necessary to help regulate your speed while transporting heavily weighted loads. An “L” restriction on your New Mexico Commercial Driver’s License (CDL) prohibits you from driving air brake-equipped vehicles. Since most semi-trucks, tractor-trailers, and full-size buses are equipped with air brakes, an “L” restriction makes it more difficult for you to secure some of the most beneficial employment options. Employers expect drivers to adhere to high safety standards, and an air brake restriction makes it more likely for them to pass on employing you. Port Jersey and Lakeland Bus Lines are examples of employers with driving opportunities that exclude you. However, with sufficient training, you can eliminate the “L” restriction.
Our New Mexico MVD CDL air brake “endorsement” practice test is expertly designed to help you develop a comprehensive understanding of air brake systems. You must successfully complete a two-part process to remove the “L” restriction that involves passing a skills test (including inspecting the air brake system) and an official knowledge test. You are required to correctly answer at least 80% of the 25 questions on the official knowledge test to earn a passing score. The practice test helps train you to achieve this score using 30 questions, similar to those on the official knowledge test, to assess your current knowledge level and direct you to the information you should study to increase it.
This New Mexico MVD CDL air brake “endorsement” practice test outperforms traditional study methods by targeting your specific learning difficulties. The practice test is based on the most recent New Mexico MVD CDL manual (New Mexico CDL Handbook 2025) and is up to date as of August 2025. If you get a question wrong, the practice test will provide a thorough explanation of the correct answer with information taken directly from the CDL manual. This approach equips you with the information you should know to meet the challenges of the official knowledge test. You will gain the advantage of receiving this information from an authoritative source and learn how to apply it to various driving scenarios.
In comparison, traditional study methods ignore your need for additional instruction and focus on training you to memorize the answers to the questions. Their failure to provide the information needed to correct your misunderstandings is detrimental to your learning potential. This approach limits you to learning surface knowledge and leaves you unprepared to confidently exhibit your skills. The practice test delivers results that fully develop your skills and self-confidence to pass the official knowledge test on your first try.
Many Newark residents call themselves residents of “Brick City,” and you can become a scholar of exceptional driving skills using the practice tests at https://driving-tests.org/new-jersey/.
