Air Brakes

While you won’t get a positive mark on your CDL license for passing the written and road tests on air brake systems of single and combination vehicles, you will get a restriction mark if you don’t. These flashcards will help you master the needed concepts in order to avoid that restriction and allow you to drive vehicles equipped with air brakes. You’ll test your knowledge of both dual and single air brake systems, when they are used, normal and abnormal findings, and troubleshooting.

Combination Vehicles

These flashcards will test your knowledge of all things related to the operation of combination vehicles. Passing the test on this is required if you want to drive any sort of combination vehicle and includes concepts like driving, inspection, coupling and uncoupling of these vehicles. Our flashcards will help you assess your knowledge of these.


If you want to drive any sort of vehicle with two or three trailers, you must have a Class A license and pass this test to get a doubles/triples endorsement. These flashcards will test your knowledge of coupling and uncoupling, checking of air brakes, and the inspection and pulling of double/triple trailers.

General Knowledge

This is the section of the CDL that covers general safety and cargo transportation rules pertaining to the driving of a commercial motor vehicle. You will need to pass this test in order to get your CDL license, and these flashcards will help you boost your knowledge in order to do well on the test.

Hazardous Material

Transportation of hazardous materials is strictly regulated by the government and the CDL endorsement for this must be updated every two years.
