Air Brakes Test - CDL is a free app to prepare yourself for the CDL air brakes test. Air brakes use compressed air to make the vehicle’s braking system work. This type of braking is very effective for safely and effectively stopping large vehicles. Due to their importance, air brakes are checked regularly to ensure that they are in good working order. To operate a bus or truck that has air brakes, you will be required to learn the information contained in the DMV’s CDL air brakes section of the study manual. To be qualified and licensed to pull a trailer with air brakes, you must also learn the information from the Combined Vehicles section of the manual. This app contains questions from the actual air brakes exam held in 2017, 2018, 2019, 2020, 2021, and 2022.
