Illinois. This App is awesome!!! It has helped me pass my CDL test for General, Combination, and Air Brakes. I look forward to using this for other endorsements as well. Great great great it is right on with the questions. Thank you thank you thank you. UPDATE: When getting the Hazmat endorsement you Must Read the Illinois CDL book on Hazardous Materials and also use this app as a study guide in order to pass the test.

Some questions is confusing and badly structured. It’s hard to tell what’s being asked. A lot of advertising. but appreciate it.
