Who needs to take the air brakes test?

Commercial drivers with a Class A and Class B commercial driver’s license will need to take the air brakes test because these are the 2 class vehicles which are equipped with the air brakes. However, these Class A and Class B vehicle drivers are automatically endorsed with ‘L’ CDL restriction. This means that the drivers are legally restricted from driving a commercial vehicle with air brakes.

Also, the ‘K’ type restriction says that the Commercial Vehicle driver is not supposed to operate vehicle with Air over hydraulic brakes or full air brakes. If a commercial driver plans to drive either of these two types of vehicles, then he or she should be ready to take the air brakes test mandatorily. Besides writing a written test for air brakes, the candidate should also be willing to take the road test with vehicle equipped with the air brakes.

In case the CDL driver is endorsed with a ‘Z’ restriction, then he or she is not allowed to operate a vehicle with Full Air brakes. If you are planning on taking the air brakes knowledge test (written) and air brakes road test for a vehicle well equipped with the air over hydraulic brakes, then you will not be eligible to operate the vehicle equipped with full air brakes.
