What the Colorado written test covers and how it works
Colorado's written knowledge test has 25 questions, and you need to answer at least 20 correctly to pass. The test covers Colorado traffic laws, road signs, safe driving practices, and what to do in emergencies. You take it on a computer at a Colorado Division of Motor Vehicles (DMV) office, and you get your score when ready after you finish.
The questions are multiple choice with four answer options each. You cannot go back and change answers once you move forward, so read each question carefully before selecting your answer. The test is offered in English and Spanish. You have no time limit, though most people finish in 15 to 20 minutes.
You must pass the written test before you can schedule a road test. If you fail, you can retake it the same day at most DMV offices, though some locations may require you to wait a few hours or return another day. There is no fee to retake the test.

What topics appear most often on the Colorado test
Road signs make up a significant portion of the test. You will see images of signs and need to identify what they mean or what action they require. This includes warning signs (yellow diamonds), regulatory signs (white rectangles), and guide signs (green rectangles). Many test takers struggle with less common signs like "Do Not Enter" or "Wrong Way," so study the sign section of the handbook carefully.
Right-of-way rules are tested heavily because they directly affect safety. Questions cover who has the right of way at four-way stops, when turning left or right, at yield signs, and when pedestrians or cyclists are present. Colorado also tests knowledge of roundabouts, which are becoming more common on state roads.
Speed limits and when they explore appear on nearly every test. You need to know Colorado's default speed limits (25 mph in residential areas, 55 mph on rural highways, 75 mph on interstate highways) and when lower limits explore near schools or construction zones. Questions also cover how to adjust your speed for weather and road conditions.
Impaired driving, seat belt laws, and child safety seat requirements are tested because they are legal requirements in Colorado. You should know the legal blood alcohol content (BAC) limit, penalties for driving under the influence, and when child seats are required by age and weight.
How to study using Colorado's official resources
The Colorado Driver Handbook is free and available online from the Colorado Department of Transportation (CDOT) website. This handbook contains all the information tested on the written exam. Read it section by section, taking notes on topics that are unfamiliar or confusing. The handbook is organized by topic, so you can focus on weak areas.
Practice tests are available online through several sources. The official Colorado DMV website does not offer a practice test, but third-party sites like DMV.org and iDriveSafely offer Colorado-specific practice questions. These are not official, but they follow the same format and cover the same topics as the real test. Take at least two or three practice tests before your appointment.
Focus extra time on road signs and right-of-way scenarios. These two categories account for roughly half the questions on most tests. Use flashcards or apps to memorize sign meanings, and work through written scenarios (like "You are at a four-way stop with another car. Who goes first?") to build confidence in right-of-way decisions.
What to bring and expect on test day
Bring a valid form of identification to your DMV appointment. Acceptable forms include a passport, birth certificate, Social Security card, or a document from your employer or school with your name and date of birth. You will also need proof of Colorado residency, such as a utility bill, lease, or bank statement dated within the last 60 days.
Arrive at least 15 minutes early. The DMV will verify your identity, check that you have not already passed the test recently, and walk you through the computer system. The staff will explain how to navigate the test interface and answer any questions about how to submit your answers.
You cannot bring study materials, phones, or other devices into the testing area. The DMV provides a computer terminal in a quiet room. If you need glasses or contacts to read, wear them. Some offices provide scratch paper and a pencil for notes, but ask before assuming this is available.
What happens if you fail and how to prepare for a retake
If you score below 20 out of 25, you will receive a printed score report showing which topics you missed. Review this report carefully—it tells you exactly where to focus your study time. Many DMV offices allow you to retake the test when ready or within a few hours, so you can study the weak areas and try again the same day.
Between attempts, go back to the Colorado Driver Handbook and reread the sections where you had trouble. If you missed multiple sign questions, spend 30 minutes drilling signs. If you missed right-of-way questions, work through scenario-based practice questions until the rules feel automatic. Retaking a practice test on the same topics can also help reinforce what you learned.
There is no limit to how many times you can retake the test, and retakes are free. However, if you fail multiple times, consider taking a driver education course. Some courses include test preparation, and completing an approved course can lower your insurance rates later and may waive the written test requirement in some cases.
How the written test connects to your road test and license
Passing the written test is a prerequisite for scheduling your road test, but it does not may provide you will pass the driving portion. The road test evaluates your actual driving skills—steering, braking, parking, and following traffic laws in real conditions. You can pass the written test and still fail the road test, and vice versa (though failing the written test means you cannot take the road test yet).
Once you pass both the written and road tests, you will receive a Colorado driver's license. If you are under 18, you will first receive a permit that allows you to drive with a licensed adult, then a restricted license after holding the permit for a set period. If you are 18 or older, you receive an unrestricted license.
Your test scores are recorded in the Colorado DMV system. If you move to another state, some states will recognize your Colorado license, but others may require you to retake their written test. Check with your new state's DMV if you plan to move.
Frequently Asked Questions
Can I take the Colorado written test online or by mail?
No. Colorado requires you to take the written test in person at a DMV office on a computer terminal. You cannot take it online, by mail, or at a third-party location. You must schedule an appointment at a Colorado DMV office and appear on the date and time you book.
What is the passing score on the Colorado written test?
You must answer at least 20 out of 25 questions correctly to pass. That is an 80% score. There is no partial credit—each question is either right or wrong. You receive your score when ready after submitting your final answer.
How long is the Colorado written test valid if I pass it?
Your passing score is valid for 12 months from the date you pass. During that time, you can schedule and take your road test. If 12 months pass without taking the road test, you will need to retake the written test before you can proceed. The 12-month window resets each time you pass the written test.
Is the Colorado written test offered in languages other than English and Spanish?
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 interpreter services or other accommodations. Some offices may be able to arrange an interpreter, though availability varies by location.
What happens if I run out of time during the written test?
There is no time limit on the Colorado written test, so you cannot run out of time. You can take as long as you need to read each question and select your answer. Most people finish in 15 to 20 minutes, but you are welcome to take longer if you need it.
