Free IL DMV Diagnostic Test 2025

  • Perfect for learner’s permit, driver’s license, and senior refresher test.

Hey, Elwood! Are you looking to go beyond the cornfields and maybe head up to Wrigley to catch a game or spend some time self-reflecting in the Garden of The Gods Wilderness? Then, you’d better speak up and find some help getting a Illinois driver’s license. If not, you might be left feeling a little salty after being taken by a group of your buddies on Cheap Trick Day. First, you’ll need to know what to expect and how to prepare yourself for success.

Illinois requires you to take a knowledge test and answer 80% of the 35 questions correctly to receive a passing score. You may already know a thing or two about how to safely operate a vehicle, but some of the questions on the official knowledge test may be worded confusingly. These are the questions you’re going to spend extra time preparing to answer. Forget about going over the things you already know! That approach is only going to lead to spinning your wheels and not being authorized to cruise down Route 66. Not to worry! You’re going to be smarter and use the premier resource for knowledge test preparation.

Our free Illinois DMV Diagnostic Driving practice test is based on the most recent Illinois Driver’s Manual and up to date as of November 2025. It’s a great resource to help you thoroughly prepare to pass your knowledge test on the first try. With questions just like the ones you’ll see on the official knowledge test, the practice test can assess your readiness. The practice test consists of 15 questions identified as the ones most commonly missed on the Illinois knowledge test. If you submit an incorrect answer, you will receive immediate feedback, including a detailed explanation of what you misunderstood. The practice test is more effective than a study guide because you are not just memorizing the answers to the question. It goes a step further and helps you learn the information that supports the correct answers.

If you are looking for other practice tests across the nation, you won’t find them in a Sears catalog. Just visit https://driving-tests.org/academy/drivers-license.
