The DC written test covers road signs, right-of-way rules, and safe driving practices

The DC Department of Motor Vehicles (DMV) written test has 25 questions, and you need to answer at least 20 correctly to pass. The test draws from the DC Driver's Manual and covers three main areas: traffic signs and their meanings, rules of the road, and safe driving behavior. You take the test on a computer at a DMV office, and you get your score when ready after you finish.

The test is not timed, so you can take as long as you need to read and answer each question. You cannot bring study materials into the testing room, and you cannot use a phone or other device. If you fail, you can retake the test the same day or schedule another appointment, but you must wait at least one day between attempts.

Traffic signs and what they mean

The DC test includes questions about standard traffic signs: stop signs, yield signs, speed limit signs, warning signs, and regulatory signs. You need to know what each sign means and what action you must take when you see it. For example, a stop sign means you must come to a complete stop, check for traffic, and proceed only when it is safe. A yield sign means you must slow down or stop if necessary to let other traffic pass.

Warning signs are yellow with black symbols or text and alert you to hazards ahead—such as curves, pedestrian crossings, or school zones. Regulatory signs are usually white with black text or black with white text, and they tell you what you must or must not do, such as speed limits, no parking, or one-way traffic. The test will show you a sign image and ask what it means or what you should do when you encounter it.

Right-of-way and intersection rules

Right-of-way questions make up a large portion of the DC test. You need to know who has the right to go first at intersections, four-way stops, and when turning. At a four-way stop, the first vehicle to arrive has the right to go. If two vehicles arrive at the same time, the vehicle on the right has the right of way. When turning left, you must yield to oncoming traffic and pedestrians. When turning right, you must yield to pedestrians in the crosswalk.

The test also covers right-of-way when merging onto highways, when a traffic light is out, and when a police officer is directing traffic. If a police officer is directing traffic, you must follow their signals instead of the traffic light. When a traffic light is out at an intersection, treat it as a four-way stop. These rules prevent crashes and are tested because they are the situations where drivers most often make mistakes.

Parking, speed limits, and safe driving practices

DC test questions cover where you can and cannot park: no parking in front of a fire hydrant, no parking in a handicapped space without a permit, no parking in a no-parking zone, and no double parking. You also need to know the speed limits in different areas—25 mph in residential zones unless otherwise posted, and the posted limit on highways and main roads. School zones have a 15 mph speed limit when children are present.

Safe driving practices tested include keeping a safe following distance (at least three seconds behind the vehicle ahead), not using a phone while driving, wearing a seatbelt, and never driving under the influence of alcohol or drugs. The test asks about what to do in bad weather, how to handle a skid, and when to use your headlights. These questions test judgment and knowledge of how to avoid crashes, not just memorization of rules.

Sample questions and where to study

The DC DMV publishes a free Driver's Manual that contains sample test questions and answers. You can read the manual from the DC DMV website or pick up a printed copy at any DMV office. The manual includes a section called "Sample Test Questions" with questions in the same format as the real test. Reading through these samples is the most direct way to prepare because they show you exactly what kinds of questions appear and how they are worded.

The DC DMV also offers a free online practice test on its website. The practice test has the same number of questions as the real test and uses the same format. Taking the practice test at least once before your appointment helps you understand what to expect and identifies topics you need to review. Many people find that reading the Driver's Manual once, then taking the practice test, then reviewing any topics they missed, is enough to pass on the first try.

Common mistakes and how to avoid them

The most common mistake is not reading the DC Driver's Manual before testing. The test is based on the manual, and questions often use the exact language from it. If you have not read the manual, you are guessing on most questions. Set aside time to read it cover to cover at least once, and take notes on sections that confuse you.

Another common mistake is misunderstanding right-of-way rules. These rules are tested heavily because they are critical to safe driving and because drivers often get them wrong in real life. If a right-of-way question confuses you during practice, read that section of the manual again and think through the scenario step by step. Do not just memorize the answer; understand why that answer is correct.

A third mistake is rushing through the test. Because there is no time limit, take your time reading each question and all the answer choices before you pick one. Some questions are worded in a way that can confuse you if you read too fast. If you are unsure about a question, mark it and come back to it after you finish the rest of the test.

What happens after you pass or fail

If you pass the written test, you move on to the road test (also called the driving test). The DMV will schedule your road test appointment or tell you how to schedule one. You must bring your permit and a vehicle that meets safety requirements to the road test. The road test is usually scheduled within a few weeks of passing the written test, depending on how busy the DC DMV is.

If you fail the written test, you can retake it the same day if you want, or you can schedule another appointment. You must wait at least one day between attempts. Many people pass on the second try because they now know which topics to focus on. When you retake the test, review the Driver's Manual again, focusing on the areas where you struggled the first time.

Frequently Asked Questions

Can I use the DC Driver's Manual during the test?

No. You cannot bring any study materials, books, or notes into the testing room. You also cannot use a phone, tablet, or any device other than the computer provided by the DMV. The test is designed to measure what you have already learned from studying the manual before you arrive.

How many times can I retake the written test?

There is no limit on how many times you can retake the test. However, you must wait at least one day between attempts. Each time you take the test, you pay the test fee again. Most people pass within two or three attempts if they study the Driver's Manual between tries.

Is the DC written test the same for all license types?

The basic written test is the same for Class D (regular car) licenses. If you are testing for a commercial driver's license (CDL) or a motorcycle endorsement, you take a different, more specialized test. Ask the DMV which test you need based on the license type you are seeking.

What if I do not pass the written test on my first try?

You can retake the test when ready or schedule a new appointment. Review the DC Driver's Manual again, focusing on the topics you found difficult. Take the practice test again to see if your score improves. Most people who fail the first time pass the second time because they now know what to expect and what to study.

Is there a study guide I can read for free?

Yes. The DC DMV publishes a free Driver's Manual that you can read from the DMV website or pick up at any DMV office. The manual includes sample test questions, traffic sign images, and explanations of DC traffic laws. This is the official study resource and covers everything on the written test.
