The Colorado Department of Motor Vehicles (DMV) requires all applicants for a driver's license to pass a written knowledge test. This test covers rules of the road, traffic signs, safe driving practices, and Colorado-specific driving laws. The written test is separate from the driving skills test you'll take later. Understanding what topics appear on this test helps you prepare thoroughly before taking it.

The test contains 25 questions in total. You need to answer at least 20 questions correctly to pass, which means you can miss no more than 5 questions. Each question is multiple choice with four answer options. The test is available in English and several other languages, and accommodations may be made for people with disabilities.
You can take the written test at any DMV office during regular business hours. The test takes approximately 15 to 30 minutes to complete once you begin. After completing your test, you receive immediate results. If you pass, you move forward in the licensing process. If you don't pass on your first attempt, you can retake the test. Most people can schedule a retest within a few days.
Colorado's written test focuses heavily on practical knowledge that directly relates to safe driving. The questions reflect situations and laws you'll encounter on Colorado roads. This means studying actual Colorado traffic laws—not just general driving principles—gives you the best preparation. The test includes questions about speed limits, right-of-way rules, parking regulations, and what different traffic signs mean.
Practical Takeaway: Before visiting the DMV, review the Colorado Driver's Handbook, which is available free on the Colorado DMV website. This handbook contains all the information covered on the written test and serves as the official source material for test preparation.
One major section of the Colorado DMV written test covers traffic signs and road markings. Approximately 6 to 8 questions focus specifically on recognizing signs and understanding what they mean. The test shows you pictures of actual signs and asks what action you should take when you see them. You need to know the color, shape, and meaning of signs to answer these questions correctly.

Warning signs are typically diamond-shaped and yellow with black lettering. These signs alert drivers to potential hazards ahead, such as curves, hills, pedestrian crossings, or construction zones. Examples include the "Curve Ahead" sign, "Pedestrian Crossing" sign, and "Slippery Road" sign. When you see a warning sign, you should reduce speed and be prepared to adjust your driving. The test includes questions asking what you should do when you encounter specific warning signs in different situations.
Regulatory signs are rectangular and communicate laws and rules. Stop signs are octagonal (eight-sided) and red with white lettering. Yield signs are triangular and red with white lettering. Speed limit signs are rectangular and white with black numbers. Do Not Enter signs are rectangular and red with white lettering. These signs tell you what you must or must not do. The test frequently asks about situations involving stop signs and yield signs, particularly regarding right-of-way rules at intersections.
Road markings on pavement also appear on the test. White lines separate traffic moving in the same direction. Yellow lines separate traffic moving in opposite directions. A solid white line means you should not change lanes. A dashed white line means you may change lanes when it's safe. A solid yellow line on your side means you cannot pass. A dashed yellow line on your side means you may pass when it's safe. The test includes scenarios asking you to identify what road markings mean in specific driving situations.
Information signs, typically rectangular and green or blue, provide directions and information about services. These include signs for rest areas, hospitals, gas stations, and route numbers. Guide signs help drivers navigate and plan their routes. The test may include one or two questions about information or guide signs, usually in context of understanding directions or locating services.
Practical Takeaway: Create flashcards with pictures of traffic signs on one side and their meanings on the other. Practice identifying signs by shape and color first, then learn their specific meanings. Spend extra time on stop signs, yield signs, and warning signs since these appear most frequently on the test.
Right-of-way questions make up a significant portion of the Colorado DMV written test, typically accounting for 5 to 7 questions. These questions ask you to determine who should go first in various intersection scenarios. Right-of-way rules exist to prevent collisions by establishing clear expectations about who has priority. Understanding these rules is essential for safe driving and passing the test.

At a four-way stop intersection with no traffic signals, vehicles must come to a complete stop. The vehicle that arrived first has the right of way and may go first. If two or three vehicles arrive at the same time, the vehicle on the right has the right of way. When facing each other, if you're going straight and another vehicle is turning left, you have the right of way. When turning, you must yield to vehicles going straight. The test includes multiple scenarios with four-way stops to test your understanding of these rules.
At intersections with traffic lights, you must follow the signals. A green light means you may go, but you must still yield to pedestrians and vehicles that have not cleared the intersection. A yellow light means the light is about to turn red, and you should stop if you can do so safely. A red light means you must stop. After stopping at a red light, you may turn right if no traffic or pedestrians are in your path, except where signs prohibit right turns on red. The test asks about situations involving traffic lights and turning on red.
When merging into traffic or entering a highway from a ramp, you must yield to traffic already on the road. This means you should adjust your speed and position to merge safely without forcing other drivers to brake or swerve. Likewise, when another vehicle is merging onto your lane from a ramp, the merging vehicle is responsible for finding a safe gap and yielding to you. The test includes questions about merging and ramp situations.
Pedestrians always have the right of way when lawfully in a crosswalk, whether marked or unmarked. You must yield to pedestrians crossing the street at intersections, even if they don't have a walk signal. If a pedestrian enters the street anywhere outside a crosswalk, drivers have the right of way, but you should still try to avoid hitting them. The test includes questions about pedestrian interactions in various scenarios.
Practical Takeaway: Practice describing intersection scenarios aloud to yourself. When studying right-of-way questions, identify the direction each vehicle is moving, what signs or signals are present, and then determine who should go first. This verbal practice helps you think through the logic of right-of-way rules rather than trying to memorize answers.
Speed-related questions appear on the Colorado DMV written test and address both posted speed limits and the concept of driving at a safe speed. Approximately 3 to 4 questions focus on speed, including specific Colorado speed limit laws and situations requiring reduced speeds. Understanding the difference between the legal speed limit and a safe speed is crucial for passing these questions and for actual safe driving.

Colorado's posted speed limits vary by road type and location. In residential areas and school zones, the speed limit is typically 25 mph unless posted otherwise. In business districts, the limit is usually 25 mph. On highways outside city limits, the speed limit is often 65 mph for cars and 55 mph for trucks. In construction zones, speed limits are reduced and strictly enforced. The test includes questions asking you to identify correct speed limits for different road types and situations.
Even when driving at or below the posted speed limit, you must adjust your speed to road and weather conditions. This concept is called "reasonable and prudent speed." If rain, snow, fog, or ice makes the road slippery, you should drive slower than the posted limit. If visibility is poor, you should slow down. If traffic is heavy, reducing speed helps prevent collisions. The test includes scenarios where the posted speed limit is legal, but driving at that speed would be unsafe due to conditions. You must recognize that the safe speed would be lower than posted.
School zones in Colorado have special speed limits, typically 25 mph when children are present. These limits usually apply during morning hours before school starts and afternoon hours when school dismisses. Some school zones have flashing lights that indicate when the reduced speed limit
