Passing the Massachusetts RMV CDL Air Brakes Knowledge Test and the on-the-road Skills Test in an air brake-equipped vehicle is what stands in your way of earning your Air Brakes qualification in Massachusetts. Passing both of these tests removes the “L” restriction from your CDL and opens up a wide range of new driving opportunities across the state. Until then, that restriction will severely limit your job potential, so preparing for these tests is a very smart move!
The official Air Brakes Knowledge Test includes 25 multiple-choice questions, and you must answer at least 16 correctly (80%) to pass. According to the Massachusetts CDL Manual, your original testing fee covers three attempts; additional fees apply after that. If you don’t pass on the first try, you must wait at least one business day before retesting. There is quite a bit of material to learn in order to prepare for this exam, with the potential for additional fees and wait time. However, our experts have crafted a series of practice tests to serve as the perfect tool for your preparations.
