Semi-trucks, tractor-trailers, and full-size buses are equipped with air brake systems to provide the force needed to stop while transporting significant amounts of weight. The Yellowhammer State requires drivers operating vehicles equipped with air brakes to exhibit the knowledge and skills necessary to understand the inner workings of their components and how to safely use them. Unless restrictions on using air brakes are removed from your Alabama Commercial Driver’s License (CDL), your driving opportunities will be limited. A thorough knowledge of the air brake system is essential to keeping you, your passengers, and fellow motorists safe. Therefore, it is crucial to receive comprehensive training on these systems and how to operate them.
