NY CDL Air Brakes Practice Test 4 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

New York City. The city that never sleeps. And with so much commerce taking place throughout the state, you can bet that obtaining the air brake qualification is a very lucrative endeavor that massively enhances your CDL. Passing the New York DMV CDL Air Brakes Knowledge Test and the Skills Test in an air brake-equipped commercial motor vehicle (CMV) is essential if you want a CDL without the “L” (air brake) restriction. If you fail the knowledge test or take the skills test in a vehicle without air brakes, the “L” restriction will remain on your CDL, which will prohibit you from operating any commercial motor vehicle equipped with full air brakes. Also, if you fail, New York requires a one-day waiting period and a retest fee before you can take the exam again. Our New York CDL Air Brakes Practice Tests are designed to help you pass on the first attempt.

Air brake–equipped vehicles travel all of the major roadways in the state, including I-87, I-90, and I-495. Major industries that require air brake-qualified drivers include agriculture, construction/infrastructure, finance and logistics, manufacturing, and tourism. With substantial industrial need and the infrastructure to support it, companies that frequently hire air brake-qualified drivers include Berle Farm, Con-way Freight, Coach USA, Eagle Rigging and Transport, Greyhound Lines, Old McDonald’s Farm/North Harbor Dairy, Perdue AgriBusiness, Rock Tech Industries, and XPO Logistics, as well as school districts statewide operating full-size school buses.

Our practice tests mirror the official DMV written test structure, based on Section 5 of the CDL Manual. Each response includes instant AI-driven feedback, detailed explanations, and a Challenge Bank that reinforces any questions answered incorrectly so you learn faster and retain the information needed to pass. The official multiple-choice Air Brakes Knowledge Test requires a minimum score of 80% to pass. Our CDL Air Brakes Practice Tests cover all the required topics while leaving out any unnecessary fluff that is not tested. You’ll learn about system components, dual systems, inspections, and safe air brake operation, as well as some of the material for the skills test. Once you have this practice test material mastered, check out another one here: https://driving-tests.org/new-york/ny-cdl-air-brake-practice-test/.

You should also consider adding valuable endorsements to your CDL, such as (N) Tanker, (H) Hazardous Materials, and (T) Doubles/Triples. Our Practice Tests can prepare you for these knowledge tests as well: https://driving-tests.org/new-york/ny-cdl-hazmat-practice-test/.
