IL CDL General Knowledge Exam Simulator 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Becoming a commercial driver in Illinois can be a long and difficult process, but we’ll help you get through it by providing access to an efficient learning tool. As you begin your learning phase, you should read the official Illinois commercial driver’s license study guide (Illinois CDL Handbook 2025). It contains important information on the various aspects of commercial driving theory, including vehicle inspections, safe driving practices, and traffic laws. The official CDL permit test consists of 30 multiple-choice questions based on this manual. You must score at least 80% to pass, leaving little room for mistakes.

Our Illinois CDL General Knowledge Exam Simulator will help you determine your level of preparedness. This intuitive tool has been designed to closely reflect the content and format of the official exam, allowing you to simulate the official testing experience on your device. The only difference is that we have omitted any timer to let you think and analyze each question before you select an answer. If you make too many mistakes, the test ends immediately, and you’ll have to start a new session. Students unfamiliar with commercial driving should study the official handbook and practice with our CDL practice tests to build the knowledge necessary to become a commercial driver. Once ready, you should use our simulator to evaluate your performance before going to the DMV office to take the official exam.

Start today and consistently train with our simulator until your scores gradually increase. Building the foundation for your commercial driving career takes time and effort. You cannot rush or skip the learning phase, but with the right tools, you can master this subject within a few weeks. There are plenty of opportunities for beginner commercial drivers in Illinois. However, employers seek professional candidates who are serious about their job. Passing the official CDL general knowledge exam should not be your primary goal; it is just a step in the licensing process. Ensure you understand even the most advanced aspects of commercial driving because your future career depends on the knowledge you build today.

Teaches you everything you need to know.

Is helpful. It is probably the most in-depth program.
It is helpful. It is probably the most in-depth program that I have ever seen. It will give you the opportunity to learn everything you need to know to take your testing. As far as my schedule goes, it was really helpful to be able to do something online and not in person, on my own time and at my own progression level, and complete the program as quickly as I could possibly complete it. I was also able to go back and retake things, retest, and relearn some of the knowledge that I needed to learn in order to upgrade my license.

Driving Tests is easy and simple.
Driving Tests is a great place to study. It really helps you prepare for any exams that you wish to take at the DMV. I love how simple it is to use and has a very modern look to it, which makes it comfortable to use. Their AI feature also helps a lot too in case you need help with a question. It has helped me obtain my CDL and a HazMat edorsment. I would highly recommend this site to those who want to 100% pass their exams for both a DL or a CDL.
