2024 IL General Knowledge Information
In order to obtain a CLP (Commercial Learners Permit) which is the first step to getting a CDL, which you will need to operate any commercial vehicle, you will first have to take and pass the General Knowledge test. The general knowledge test consists of 50 multiple choice questions, and a score of 80% (40 out of 50) or better is required to pass.
You will have one hour to complete the General Knowledge test, and will be allowed to miss only 10 questions before you have to start the process over again. If you fail you will not be able to retake the test on the same day, so you will have to make another trip.
These questions are all covered by the 2024 Illinois CDL drivers’ manual, but it can be confusing and there is a lot of information in the book. Our practice tests take the stress out of what questions you will encounter and makes passing a breeze. We have 400 questions that pertain to the General Knowledge exam spread out over eight practice tests available free. Please make sure you take all the tests and have a good understanding of the material before heading out to take the actual exam.
