Whether driving through the foothills of Georgia’s Appalachian Mountains in the north, the Piedmont plateau in the south, or the hilly suburbs in the west, you’ll face a lot of steep hills, making the use of air brakes essential for control and safety. You’ve come to the right place for practice materials to prepare for the official DDS air brakes knowledge test. If you don’t pass it, your CDL will include the restriction “L,” indicating that you’re not allowed to drive CMVs with air brakes. Since virtually all semi-trucks and tractor-trailers are equipped with air brakes, getting a Class A CDL without passing the test is a bit pointless. In fact, in Georgia, the air brakes qualification is a requirement of most companies due to how prevalent this braking system is, notably in Georgia’s agriculture, manufacturing, and transportation sectors.
Organizations in the Peach State that typically require drivers to have this qualification include trucking and logistics, charter bus services, and school transportation. The state has a strong trucking industry, with companies such as UPS and Saia headquartered in Georgia that require drivers to operate large freight vehicles equipped with air brakes. Charter bus services, including Southeastern Stages, based in Atlanta, require drivers with air brake qualifications. School buses in Georgiaare typically equipped with air brakes as well. With the “L” restriction prohibiting you from operating CMVs with air brakes, your job prospects would be severely limited.
