Imagine you’re driving on the streets of Chicago, which is known for its heavy traffic and complex road network. You’re on a one-way street and want to turn left onto another one-way street. According to the official Illinois Rules of the Road handbook (Illinois DMV Handbook (IL Driver's Manual) 2025), Illinois allows you to turn left on red from a one-way street onto another one-way street, unless there’s a sign indicating otherwise. But before you do, you must come to a complete stop and yield to pedestrians and other traffic.
As you begin your learning phase, you should dedicate a few weeks to learning and mastering driving theory. During this time, students who engage in active learning often achieve better results than those who rely on traditional study methods. Our Illinois DMV Written Test Study Guide practice test has been designed to closely reflect the content and format of the official written knowledge exam. This intuitive tool helps you improve your knowledge and confidence while giving you an idea of what to expect on exam day. It is up to date as of October 2025, so you will always practice with the latest version, which reflects the latest updates brought by DMV rules or state law. All 20 questions are based on the official Illinois Rules of the Road handbook. There are multiple answer choices, but only one is correct. Please avoid rushing and read every question twice before you select an answer.
The “Test settings” menu on the left side of the page can be used to customize your testing experience. From here, you can activate several features, including the voice-over function and the ambient music. These two features combined can help you stay focused even in distracting environments. If you have difficulty reading the text, use the slider to increase the font size until it’s easier to read.
While your learning phase may not have a speed limit, it is crucial to adopt a systematic approach and study driving theory at your own pace. Achieving a passing score on the official written knowledge test should not be your primary goal. We’ll help you become a safe and responsible driver, but you must put in the time and effort necessary to achieve this goal.
