Illinois DMV Marathon [93 Hardest Questions]

Perfect for learner’s permit, driver’s license, and Senior Refresher Test
Based on official Illinois Driver's manual
Triple-checked for accuracy
Updated for March 2025

This massive Marathon is special. It contains all 93 of our most challenging questions from the “hardest” tests, but that’s not all. It was designed to help you maximize your knowledge of the material, covering all the “blind spots” you might have. So if you make a mistake as you work your way through the Marathon, the system will remember that you got it wrong and will show you that question once again at a later point -- until you finally provide the correct answer. If at any point you feel that you need to practice in a more controlled environment, just go back to our regular tests -- every time you make a mistake in one of those, the system marks your answer as wrong and prompts you the correct answer, complemented by an explanation of why it is so. Once you’ve passed this Marathon test, you can be sure that you did everything possible to succeed!

Our commitment to accuracy and quality in our practice tests

Explore our rigorous, multi-tiered verification process that ensures each question mirrors the official manual for unparalleled accuracy.

Written by Andrei Zakhareuski Updated over a week ago

At Driving-Tests.org, we understand the importance of reliable and accurate practice tests to help you prepare for your DMV exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.

Here's an inside look at how we maintain the highest quality in our practice tests.

Content Creation and Verification Process

Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly.
Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.

Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
