NY CDL Air Brakes Practice Test 2 2025

Keep your eyes on the road and your hands on the wheel, and know how to operate your air brakes! Commercial truck drivers interested in the best driving opportunities should adhere to this advice and avoid having an “L” restriction on their New York Commercial Driver’s License (CDL). The “L” restriction prohibits you from operating vehicles equipped with air brakes. Since most semi-trucks, tractor-trailers, and full-size buses are equipped with air brakes, you will have a more difficult time qualifying for jobs in the “City That Never Sleeps” with transportation providers, such as On Time Trucking and the Metropolitan Transportation Authority. Air brakes help you slow down to navigate changing road conditions and stop in heavily congested traffic. If you want to get the maximum benefits from your CDL, you should seek an effective resource to teach you about air brake operations.

Our New York DMV CDL air brake “endorsement” practice test will set you on the fast track to becoming an air brake-qualified driver. You must pass a skills test in a vehicle with air brakes (including conducting an inspection of the air brakes) and an official Air Brakes knowledge test to remove the “L” restriction. The official knowledge test requires you to correctly answer at least 80% of its 25 questions to earn a passing score and avoid waiting ten days to retest.

This New York DMV CDL air brake “endorsement” practice test can act as the criteria for assessing your readiness to pass the official knowledge test. The practice test provides you with a real-time assessment of your proficiency and identifies the information you need to study to increase it. You will be provided with 30 questions, similar to those on the official knowledge test, to prepare you for the challenges you may face.

The practice test is based on the most recent New York DMV CDL manual (New York CDL Handbook 2025) and is up to date as of September 2025. If you get a question wrong, you will receive feedback from the practice test that contains information directly from the CDL manual to correct your answer. The CDL manual is the most authoritative source available, and you can confidently apply it to your driving practices.

While you may consider more traditional study methods, the practice test outperforms their limited capabilities to provide comprehensive instruction. Traditional study methods are one-dimensional and depend on your ability to memorize the answers to the questions without helping you to correct the answers you get wrong. The practice test provides the information necessary to overcome your learning obstacles and increases your chances of passing the official knowledge test on your first try.
