Removing the “L” restriction from your Commercial Driver’s License (CDL) is a crucial step for many commercial motor vehicle (CMV) drivers. That tiny little “L” code makes it illegal for you to operate CMVs equipped with air brakes and constitutes a serious job limitation on your CDL. If you are looking for the best resource for passing the New Jersey MVC CDL Air Brakes Knowledge Test, then you are at the right place and on track for a huge jump in job opportunities. In New Jersey, air brake-qualified drivers are required in multiple major industries, including construction, pharmaceuticals, port logistics, tourism, and waste management. Major employers, such as Academy Bus Lines, Amazon Transportation, Caterpillar equipment dealers, FedEx Freight, NJ Transit, and every school district operating full-size buses, all require air brake-qualified drivers. With so much demand, our experts have crafted a series of New Jersey CDL Air Brakes Practice Tests to help you ace the official exam on your first attempt.
In order to have the “L” removed from your CDL, you’ll need to pass the New Jersey MVC CDL Air Brakes Knowledge Test and the Skills Test in an air brake-equipped vehicle. In New Jersey, a failed air brakes test requires a seven-day waiting period (quite a bit longer than in most other states) and a potential fee before you can test again. Avoiding that delay and added fees is especially paramount in this state.
To pass the official written multiple-choice Air Brakes exam, you must score at least 80%. Our Air Brakes Practice Tests are based on the MVC exam format. You’ll learn how modern air brake systems work, proper inspection steps, emergency braking procedures, dual-system operation, low-pressure warnings, and governor cycle behavior, and components such as tanks, compressors, valves, and brake chambers.
Our practice tests include real-time feedback, which has been shown to increase retention and speed learning. They also feature an interactive CDL Manual and a Challenge Bank that recycles missed questions until answered correctly.

While you’re at it, you should consider adding valuable endorsements to your CDL, such as (N) Tanker, (H) Hazardous Materials, and (T) Doubles/Triples. Our Practice Tests can help you prepare for these knowledge tests as well: https://driving-tests.org/new-jersey/nj-cdl-hazmat-practice-test/.
