Top Tips For Studying for the Air Brakes Test
Why Should I Get My Air Brakes Endorsement?
If you're looking into getting your commercial driver’s license, you may discover that the general knowledge test isn't the only test you need to take if you want a full Class A license. In many states, failing the air brakes test means that you get a restriction placed on your license. This restriction keeps you from driving trucks with air brakes, and as more fleets move to newer trucks, a growing number of trucks do come equipped with air brakes.
Adequately preparing for and passing the air brakes test is the only way to get this restriction off of your license and be free to drive any vehicle in your license class.
Keep in mind that removing restrictions and adding endorsements can be good for your career. Truck driving job openings may swell 5% between 2014 and 2024, and the average salary in this field is an impressive $39,520 (, 2016). To qualify for as many openings as possible, you need to have as few restrictions as you can.
Whether you're taking the air brakes test for the first time or retaking it, the process is the same. Learn more about what to expect below and give our practice test a try.

Requirements for Air Brakes Endorsement
As noted, air brakes is one of the few endorsements or restrictions that requires you to take a skills test.

Since this is a federal requirement, all 50 states the District of Columbia require both a written test and a skills test.
Fees vary from state to state; the charges $5.00 (2016). The charges $10 for the written test and $56 for the practical test (2016).
Passing the air brakes test when you first get your commercial driver’s license is probably the quickest way to move this restriction from your license, since it saves you from having to take a second road test. For that reason, you may want to ensure that you have access to a vehicle with air brakes for your road test. In addition, make sure that you feel completely comfortable using air brakes by the time you finish your trucking course. They are completely different from hydraulic brakes, and your road test may involve using them multiple times in different situations.
Start getting a feel for air brakes and this endorsement with a practice test. It's a great way to find out what you still need to study and how you can improve.
