Driving commercial motor vehicles (CMVs) with air brakes requires specialized knowledge and skills, including passing the New Jersey MVC CDL Air Brakes knowledge test. If you fail, you must wait seven days before testing again. Our practice test is your key to passing on the first attempt. If you don’t pass, your CDL will include the restriction “L,” preventing you from operating CMVs with air brakes. In New Jersey, the Appalachian Highlands in the northwestern part of the state present hilly terrain that challenges braking systems. Furthermore, long-distance travel along the coastal plains of the southeast necessitates the use of air brakes and qualified drivers. The stop-and-go traffic in urban areas like Newark and Jersey City also calls for precise braking provided by air brakes. As most semi-trucks and tractor-trailers rely on air brakes, removing the “L” restriction is essential.

Industries across the Garden State rely on drivers with the air brake qualification, including logistics (ports), pharmaceuticals, and tourism (Atlantic City and Jersey Shore). Notable companies requiring the air brakes qualification include FedEx Freight and Amazon Transportation in the freight industry, New Jersey Transit in the public transportation sector and Caterpillar equipment dealers in the construction sector. Additionally, Academy Bus Lines requires air brake-qualified drivers in the charter bus industry, as do all school districts operating full-size school buses. The “L” restriction severely limits your job prospects, making the above-listed job prospects unattainable.

About the New Jersey CDL

Our practice tests help you pass your air brake knowledge test. But, the information you learn will also be useful as you practice inspecting and operating CMVs to pass your skills test. The official MVC test ensures you’re proficient in air brake systems, effective operation, and air-brake inspection procedures. The skills test includes inspecting components, testing for air pressure and leaks, and operating a vehicle equipped with air brakes. The written Air Brakes knowledge test features multiple-choice questions based on the official New Jersey CDL manual (New Jersey CDL Handbook 2026) and requires a score of at least 80% to pass.

Our New Jersey MVC CDL Air Brakes Practice Tests mirror material used on the official knowledge test and mimic the content and format you will face. Additionally, our practice test questions and answers provide responses in real time, a scientifically proven method for improving retention. With our resources, you can learn quickly and be confident of passing your official exam.
