The first step on the road to obtaining your Illinois driver's license should be to thoroughly study the Illinois Rules of the Road, also known as the Illinois driver's handbook or driver's manual.
This manual is available both online in HTML format and as a downloadable PDF file requiring the free Adobe Reader software to read. The Illinois driver's manual is also available at your nearest Illinois Secretary of State driver services office.
English isn't the only language the manual is published in. In fact, you can download versions in Polish and Spanish as well:
Sample questions that may appear on the written licensing test are sprinkled throughout the manual. The answer key to these questions appears in the Answers to Study Questions section.
For those seeking a commercial driver's license (CDL), there is a handbook just for you. At 161 pages, the Illinois Commercial Driver's License Study Guide is a comprehensive manual that will help you pass the required CDL written exam.
