FREE 2024 Georgia (GA) Air Brakes Quick Review 2

2024 GA Air Brakes Information

Most commercial vehicles utilize an air brake system over the traditional hydraulic brake system of passenger cars due to the "unlimited" supply the included air compressor and storage tanks can create. This eliminates the need to add hydraulic fluid when connecting a trailer.

The air brakes test covers the air brake system in detail, including appropriate air loss, brake lag, system components, and more. There are a total of 25 multiple choice questions on the air brakes exam, and you must score 80% (20 out of 25) to pass the exam. We have complied 100 questions you will find on the air brakes exam. These questions are based off the 2024 Georgia CDL drivers’ manual.

The air brakes exam is different than the other endorsement tests, it actually serves as a restriction on your license. You are able to get a CDL without the air brakes test but will not be allowed to drive any vehicle that is equipped with air brakes because your license will have a "L" restriction.

Possible Answers:

The speed of the air compressor.
Air pressure applied to the brakes.
When air is pumped into the air tanks.
Answer:
When air is pumped into the air tanks.
Explanation:
The governor controls when the air compressor will pump air into the air storage tanks. When air tank pressure rises to the "cut-out" level around 125 psi, the governor stops the compressor from pumping air. When the tank pressure falls to the "cut-in" pressure around 100 psi, the governor allows the compressor to start pumping again.
