Illinois, known for its diverse economic portfolio of industries, is a major transportation hub for its area of the country and a great state to drive in! Truck drivers in the Land of Lincoln enjoy well-designed infrastructure and competitive wages. But before you can become a commercial truck driver, you first need an Illinois commercial driver’s license (CDL), which is a license earned by passing a series of exams that test your knowledge and skills in the world of trucking. These exams aren’t easy, which is why we’ve designed a series of free Illinois CDL practice tests (based on the same material as the real exam) to help you study, completely risk free. Plus, you’ll be one of the few who can feel confident on test day, because you’ll have already mastered the knowledge needed to ace the exam! Get started with your Illinois trucking career now!
