CA DMV Written Test Simulator – Study Online 2025
- Perfect for Senior Refresher Test
- Based on official California Driver's manual
- Triple-checked for accuracy
- Updated for January 2025
The possibilities are nearly unlimited: Drive to Disneyland or Napa Valley. Take in the sights from the Tioga Pass Road or the Death Valley Scenic Byway. And, of course, commute to work anywhere in the state by car. These are just a few of the things you’ll be able to do once you get a California driver’s license.
What’s standing in your way? Three official tests, for one thing. One of the most important requirements for a driver’s license is to pass a vision test, a knowledge test, and a behind-the-wheel drive test. Passing the knowledge test demonstrates an adequate grasp of driving theory. The number of questions on your knowledge test will depend on your age. If you’re under 18, the test will have 46 questions, and you must answer at least 38 of them correctly. If you’re at least 18 years old, the test will have 36 questions, and you must answer at least 30 of them correctly. All knowledge test questions are based on the official driver’s manual (California DMV Driver's Handbook 2025: Interactive Manual w/Audio).
If you fail the knowledge test, you may take it again, but you’ll have to wait a full week if you’re under 18. If you fail the knowledge test three times in a row, you’ll have to restart the application process. Unfortunately, failure happens all too often. In 2020 – 2023, 55.3% of applicants – more than half – failed the knowledge test on their first try.
Our knowledge test preparation program includes various interactive tools you can use to greatly improve your chances of passing. Once you’ve used our tools to learn all about safe driving, we have one final study aid for you: our special Exam Simulator test. This test will give you more of a feel for the official knowledge test itself.
This Exam Simulator test closely resembles official knowledge test conditions. The test questions are based on the official driver’s manual, just like those on the official DMV knowledge test. The passing score is 83%, just like the official test. There are no hints or explanations to help you. And the test ends prematurely if you fail it (i.e., you miss more than 17% of the questions).
This Exam Simulator test is so realistic that you may even experience a little test anxiety when taking it. That’s how you would have reacted to the official knowledge test! By giving you a realistic test experience now, your fear of the unknown will be reduced, and you’ll be more confident that you’re ready to ace the official test.
Good luck!

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.
