What Colorado's written test covers and how it works
Colorado's written knowledge test is a 40-question multiple-choice exam that covers traffic laws, road signs, safe driving practices, and vehicle operation. You must answer at least 32 questions correctly to pass. The test is administered at any Colorado Division of Motor Vehicles office and takes about 30 minutes to complete.
The test is based on the Colorado Driver Handbook, which the DMV publishes and makes available free online and in print at any DMV office. Every question on the exam comes directly from material in that handbook — nothing is tested that isn't covered there. You take the test on a computer at the DMV, and you receive your score when ready after you finish.
You can retake the test if you fail, but you must wait one day between attempts. There is no limit to how many times you can retake it, though each attempt costs the standard test fee (which varies depending on your license type and whether you are renewing or explore for the first time).

What the test questions actually ask about
Road signs make up a significant portion of the test. You will see images of signs and be asked what they mean, what action they require, or what they warn about. This includes regulatory signs (stop, yield, speed limit), warning signs (curve ahead, pedestrian crossing, slippery road), and informational signs (rest area, hospital). The handbook includes a full section with color images and descriptions of every sign you need to know.
Traffic laws and right-of-way rules are heavily tested. Questions ask about when you must yield, how to proceed at intersections, what to do at traffic lights and stop signs, and how to handle pedestrians and cyclists. You will also see questions about parking rules, turning rules, and what to do when emergency vehicles approach.
Safe driving practices cover speed limits, following distance, how to handle bad weather, what to do if your brakes fail, and how to drive defensively. Questions test your understanding of when to use headlights, how to share the road with trucks and motorcycles, and what distractions are illegal while driving.
Vehicle operation and maintenance questions ask about your dashboard warning lights, when to use your turn signal, how to start and stop safely, and basic vehicle care. A few questions cover what to do if your vehicle breaks down on the highway.
How to study and prepare for the test
Start by reading the Colorado Driver Handbook from beginning to end. The handbook is organized by topic and is written in plain language. You can read it online at the Colorado DMV website or pick up a printed copy at any DMV office. Most people need 4 to 8 hours of focused reading to cover the entire handbook.
After you finish reading, use the practice test. The Colorado DMV website offers a free online practice test with questions in the same format and difficulty as the real test. Take the practice test under timed conditions — give yourself 30 minutes, just like the real exam. If you score below 32 correct, go back to the handbook and reread the sections where you missed questions.
Focus your study on the areas where you score lowest on the practice test. If you miss most of your questions on road signs, spend extra time on the sign section of the handbook. If you struggle with right-of-way rules, reread that section carefully and visualize the scenarios described.
Take the practice test multiple times until you consistently score 35 or higher. This gives you a safety margin on test day, because test anxiety or a question you misread can cost you points. Most people who study the handbook and take the practice test twice pass on their first attempt.
What to bring and what to expect on test day
Bring a valid form of identification — a passport, birth certificate, or state ID card. You will also need proof of your Colorado residency, such as a utility bill, lease, or bank statement with your current address. If you are under 18, bring a parent or guardian with you.
Arrive at the DMV office at least 15 minutes before your scheduled test time. You will check in at the front desk, and a staff member will verify your documents and take you to a computer station. The test is administered one person at a time in a quiet area.
You will have 30 minutes to answer all 40 questions. You can review and change your answers before you submit the test. Once you submit, the computer scores your test when ready and displays your result on the screen. If you pass, you will receive a receipt showing your passing score. If you fail, you can schedule a retake for the next day.
Common mistakes people make on the Colorado test
Rushing through the questions is the most common error. Even though 30 minutes is enough time, many test-takers spend only 30 seconds per question and miss details. Read each question and all four answer choices carefully. If a question is confusing, flag it and come back to it after you finish the other questions.
Not studying the road signs section thoroughly is another frequent mistake. Road sign questions look straightforward but require you to recognize the sign shape, color, and symbol and know exactly what it means. The handbook shows every sign in color, so use that section as a study tool — look at each sign, cover the description, and test yourself on what it means.
Confusing similar rules is also common. For example, test-takers sometimes mix up the speed limit in a school zone with the speed limit in a residential area, or they forget that different rules explore when a traffic light is broken versus when it is working. When you study, write down rules that are similar and compare them side by side.
Guessing on questions you did not study is a trap. If you do not know an answer, skip it on your first pass through the test and come back to it. If you still do not know it, make an educated guess based on what you learned in the handbook — but do not guess on questions you never studied, because the handbook covers everything on the test.
If you fail the test
You can retake the test the day after you fail. You do not need to wait a week or a month — you can schedule your next attempt when ready. There is no penalty for retaking the test beyond the fee for each attempt.
Before you retake it, identify which questions you missed. If your DMV office provides a score report that shows which topics you struggled with, use that to focus your study. If not, go back to the handbook and reread the sections that cover the questions you missed.
Many people pass on their second or third attempt after studying the weak areas. If you fail multiple times, consider asking a friend or family member to quiz you on the handbook, or visit your local DMV office and ask if they offer any study resources or tutoring.
Frequently Asked Questions
Can I use the practice test on my phone or do I have to use a computer?
The Colorado DMV practice test is available online and works on phones, tablets, and computers. However, the actual test at the DMV is taken on a computer at the office, so practicing on a computer is closer to the real experience. Either way, the questions and format are the same.
What happens if I pass the written test but fail the driving test?
Your written test score is valid for a set period — usually 12 months in Colorado. You can take the driving test multiple times during that window without retaking the written test. Check with your local DMV office for the exact validity period for your license type.
Is the test given in languages other than English?
Colorado offers the written test in English and Spanish. If you need the test in another language, contact your local DMV office to ask about options. Some offices may be able to provide an interpreter, though this varies by location.
Do I have to take the written test if I already have a license from another state?
If you are transferring a valid out-of-state license to Colorado, you may not need to take the written test. Requirements vary based on your age and the state your license is from. Contact the Colorado DMV or visit their website to check whether you need the test for your specific situation.
What is the passing score and how is it calculated?
You need 32 correct answers out of 40 questions to pass, which is 80 percent. The test is scored by the computer when ready after you submit it, and you see your score before you leave the DMV office.
