CO DMV Written Test Simulator – Study Online 2025
- Perfect for learner’s permit, driver’s license, and Senior Refresher Test
- Based on official Colorado Driver's manual
- Triple-checked for accuracy
- Updated for January 2025
Dreaming of driving to Vail or Aspen for some skiing? Or driving to the Red Rocks Amphitheatre to see your favorite band perform while you take in the vistas all around? Or seeing the Rocky Mountains National Park via Trail Ridge Road? Whatever your fancy, if you want to drive yourself there, you must have a driver’s license.
You must pass three tests to qualify for a driver’s license: a vision test, a driving knowledge test, and a driving skills (road) test. The knowledge and vision tests are also the two tests required for an instruction (learner’s) permit. If you’re under 18 or have never driven before, you must obtain an instruction permit to allow you to practice driving under adult supervision.
The knowledge test has 25 multiple-choice questions covering road signs and signals, driving under the influence, driving rules, safety rules, and legal items. All questions are based on the official driver’s manual (Colorado DMV Handbook (CO Driver's Manual) 2025). The passing score is 80%.
Perhaps you’re sure that all you have to do to pass the knowledge test is read the official driver’s manual a couple of times. Many other aspiring drivers learned the hard way that wasn’t true. In 2020 – 2023, 39.8% of aspiring drivers failed the Colorado knowledge test on their first try. Therefore, we’ve provided you with interactive test preparation tools, including a graduated series of practice tests also based on the official driver’s manual. Each practice test is accompanied by our AI-based assistant, which can give you hints and explanations to help you answer the test questions and speed up your learning process.
Now we have one more step for you: take our Exam Simulator test.
This Exam Simulator runs in Simulated Exam Mode, resembling official exam conditions. The test consists of 25 questions based on the official manual, just like those on the official DMV knowledge test. The passing score is 80%, just like the official knowledge test. Our AI assistant is unavailable for this test, so there are no hints or explanations to help you. On this test, you’re on your own, just like on the official knowledge test.
By giving you a realistic exam experience now, you’ll learn what to expect on the official knowledge test. This will reduce the chance of an unpleasant surprise on the official knowledge test, relieve any anxiety about the knowledge test, and build your confidence that you can easily ace the official test on your first try.
Good luck!

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.
