You may have falsely assumed that all study methods are equally effective in helping you remove the air brakes restriction from your Wisconsin commercial driver’s license (CDL). If so, you obviously weren’t familiar with our CDL Air Brakes practice test series. This third free Air Brakes practice test continues to develop your knowledge of air brake systems, using an innovative approach. The practice test is expertly designed to meet your learning objectives. Just as you wouldn’t dare use margarine to make a butter burger, you shouldn’t try to learn about air brakes from anything other than superior training. The practice test is expertly designed to meet your learning objectives.
Providing a real-time evaluation of your current air brake system knowledge, our CDL Air Brakes practice test can effectively teach you the essential skills to remove your restriction. Removing an air brakes restriction requires you to pass an official Air Brakes knowledge test and a skills test exhibiting your understanding of how to inspect and operate the system. The practice test uses a simulated testing environment and has an interactive capability to grade your answers. It contains questions that are similar to those on the official knowledge test. You must correctly answer at least 80% of the 25 questions on the official knowledge test to pass. Building upon the skills you learned through Entry-Level Driver’s Training (ELDT), the practice test teaches the critical information you must know to begin driving air brake-equipped vehicles.
