Do you need an Air Brakes endorsement for your commercial driving learners permit? Our NC CDL practice test air brakes quiz can help you achieve the necessary grade to earn this endorsement, when you sit the DMV written test. It is quite common for commercial driving applicants to require an L endorsement air brakes qualification, as all medium-weight Class B vehicles and heavy-weight Class A vehicles must operate with an air brake system. Only if you intend to drive a standard Class C commercial vehicle such as a taxi would the DMV CDL air brakes test be unnecessary. Any driver operating an air brake-equipped vehicle must have some basic knowledge of air brake components, maintenance, repair and application, explanations of which can be found in the Air Brakes section of the permit test study guide. This CDL practice test NC air brakes quiz is designed to help you apply that information practically, before sitting the DMV permit test.

You do not have to be 100 percent certain on the specific commercial driving role you intend to fulfil at this stage; if you know you will be working in a box-truck, school bus, flat-bed, multiple-trailer vehicle, tank-truck or any other Class B or Class A vehicle, you can start using this Class B and Class A practice test for North Carolina students to prepare for the endorsement permit test.
