The Heart of Dixie features major highways like I-65, I-20/I-59, I-10, and I-85, filled with steep grades, heavy traffic, and long-haul demands that necessitate the use of air brakes in virtually all semi-trucks and tractor-trailers. If you plan to drive commercial motor vehicles (CMVs) equipped with air brakes and realize the importance of passing the official {state-agency} Air Brake Test, then our practice materials are needed. Without passing, your CDL will include the restriction “L,” preventing you from driving CMVs with air brakes. That’s quite a limitation on your job prospects. Alabama’s terrain includes rolling hills and flat plains, as well as steep grades and high humidity (in Birmingham and Huntsville), making air brake qualification vital for safe navigation. Preparing for this test is wise because air brake qualifications are a standard requirement for most companies due to the widespread use of this braking system.

In Alabama, there are multiple industries that rely on air brake-qualified drivers, including logistics and freight, charter bus services, educational services, manufacturing, and agriculture. Companies like UPS, FedEx, Old Dominion Freight Line, Greyhound, Southern Coaches, and Capital Trailways require air brake certifications. Even to drive a school bus in this state, you will likely need the qualification as most of them are now equipped with air brakes. Mercedes-Benz, Honda, and Hyundai depend on air brake-certified drivers. Also, poultry, timber, and cotton are regularly transported in vehicles equipped with air brakes. That’s a tremendous amount of opportunities, so let’s take a look at the requirements.

There are two parts to the test: the skills test and the knowledge test. The skills test will require you to physically inspect and identify the parts of an air brake system, as well as operate a vehicle equipped with air brakes. The multiple-choice knowledge test includes questions covering the state’s CDL manual and requires a score of 80% or higher to pass.

We have carefully designed our Alabama CDL Air Brakes Practice Tests to mimic the content you will face on the official DMV knowledge test. With our practice test questions and answers, you can learn the material quickly and feel confident as you near the day of your official exam. Once you feel prepared, simply schedule the knowledge test at the DMV, pay any fees, and take the test.
