IA DOT Written Test Simulator – Study Online 2025
- Perfect for learner’s permit, driver’s license, and Senior Refresher Test
- Based on official Iowa Driver's manual
- Triple-checked for accuracy
- Updated for January 2025
With an Iowa driver’s license, you can drive all the way across the state from the Missouri River to the Mississippi River via Route 20 and take in the vistas along the way. Or drive on the Great River Road along the Mississippi River and do some sightseeing. But if you don’t have a driver’s license, you’ll have to take a bus.
To get a driver’s license, you must meet many requirements. One crucial requirement is to pass the official knowledge test for an instruction permit, which will allow you to practice supervised driving. However, passing the knowledge test isn’t as easy as you may think. In 2020 – 2023, about 39.4% of aspiring drivers failed the knowledge test on their first attempt. It would seem that just reading the official driver’s manual (Iowa DMV Handbook (IA Driver's Manual) 2025) shortly before the knowledge test may not prepare you well enough to pass the test.
We want to make sure that you pass. We’ve created a knowledge test preparation program with various interactive tools you can use to ensure you absorb and memorize all the relevant information. It includes an audiobook version of the official driver’s manual that you can listen to anywhere. It also includes a series of practice tests based on the official manual, and an automated assistant to help you answer the questions on these practice tests. The assistant can supply hints and explanations of the correct answers to speed up the learning process. We hope you’ve been following our program and have learned a lot about safe driving. We guarantee our program works! If you follow the entire program and still fail the knowledge test, we’ll cheerfully refund your money.
Do you think you’re ready to take the official knowledge test now? Let’s make sure you are before you go to the DOT for the test! This Exam Simulator test closely resembles official exam conditions. The Iowa permit practice test consists of 25 questions based on the official manual, just like those on the official DOT permit test. The passing score is 80%, just like the official permit test. There are no hints or other aids to help you answer the test questions. The test is as close to the official permit test as we can make it!
If you tend to experience test anxiety when taking official tests, you may even experience a little anxiety when taking this Exam Simulator test. That’s OK! By giving you a sample exam experience now, your fear of the unknown will be reduced, and your anxiety level may actually drop.
Good luck!

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.
