The DMV written test covers road signs, traffic laws, and safe driving practices specific to your state

The DMV written test — sometimes called the knowledge test or permit test — asks you questions about traffic signs, right-of-way rules, speed limits, and how to handle common driving situations. You answer multiple-choice questions on a computer or paper, depending on your state's setup. Most states require you to score 80 percent or higher to pass. The test is not the same in every state: California's test differs from Texas's, which differs from New York's, because each state writes its own traffic laws and emphasizes different hazards.

You take this test before you get your learner's permit or your full driver's license, depending on your state's licensing structure. Some states call it the permit test because you need to pass it to get a learner's permit first. Other states combine the written test and the road test into a single licensing day. The test itself usually takes 20 to 40 minutes, though you are allowed extra time if you need it.

Key Takeaways

  • Each state writes its own DMV test based on its own traffic laws, so the questions you see depend on where you live.
  • You typically need to score 80 percent or higher to pass, though some states set the passing score at 70 percent.
  • The test covers road signs, traffic laws, right-of-way rules, and safe driving practices — not driving skills, which are tested on the road test.
  • Most states let you take the test on a computer at a DMV office, and many offer the test in multiple languages.
  • You can study using your state's official driver's manual, which is free and covers everything the test asks about.

What the test actually covers

The written test asks about road signs and what they mean. You will see pictures of signs — stop signs, yield signs, speed limit signs, warning signs — and choose what each one tells you to do. You will also answer questions about traffic laws: when you can turn right on red, how far back you have to stay from a fire truck, what to do at a four-way stop, whether you can pass on a solid yellow line.

The test includes questions about safe driving practices. These ask what you should do in rain, how to handle a skid, when to use your headlights, what to do if your brakes fail. Some questions test your understanding of right-of-way — who goes first at an intersection, how to yield to pedestrians, what happens when two cars arrive at a stop sign at the same time. A few questions usually cover parking rules, seat belt laws, and what to do if you are pulled over.

The test does not ask you to demonstrate driving skills. That happens on the road test, which is separate. The written test is purely knowledge: you read a question or look at a picture, and you choose the right answer from the options given.

How many questions and what score you need

Most states ask between 30 and 50 questions on the written test. California asks 36. Texas asks 30. New York asks 20. The exact number varies by state, and your state's DMV website will tell you the number for your test.

The passing score is usually 80 percent in most states, which means you can miss 20 percent of the questions and still pass. Some states set the passing score lower — 70 percent in a few places — and a small number of states require 85 percent. Your state's driver's manual will tell you the exact passing score for your state. If you do not pass, you can usually take the test again the same day or within a few days, depending on your state's rules.

How to study for the test

Your state's official driver's manual is free and covers everything on the test. You can read it from your state's DMV website or pick up a printed copy at any DMV office. Read through the manual once, paying attention to sections on road signs, traffic laws, and right-of-way rules. These are the areas most tests focus on.

After you read the manual, take practice tests. Many state DMV websites offer free practice tests online that use the same format and types of questions as the real test. Taking a practice test tells you which topics you need to study more. If you score below 80 percent on a practice test, go back to the manual and reread those sections. Some people study for a few days; others study for a few weeks. Most people who read the manual and take one or two practice tests pass on their first try.

You can also study using third-party apps and websites, but stick with materials that are based on your state's official driver's manual. A test prep site designed for another state will have different questions and may teach you rules that do not explore where you live.

Where to take the test and what to bring

You take the written test at a DMV office in your state. Call ahead or check your state's DMV website to find out whether you need an appointment or whether you can walk in. Some states require appointments; others take walk-ins on a first-come, first-served basis. Wait times vary widely depending on the office and the time of day.

Bring your state ID or passport, your Social Security number, and proof of your address — a utility bill, lease, or bank statement usually works. If you are under 18, bring a parent or guardian and any documents they require. Your state's DMV website lists exactly what documents you need for your situation.

Most states offer the test in English and in other languages. If English is not your first language, ask your DMV office which languages are available. Some states offer the test in Spanish, Chinese, Korean, Vietnamese, and other languages. A few states allow you to bring an interpreter, though rules vary.

Test day: what happens and how long it takes

You arrive at the DMV, check in, and wait to be called. When it is your turn, a staff member will verify your identity and ask you to sign a form confirming you understand the rules of the test. You will then sit at a computer or receive a paper test, depending on your state's system. Most states use computers now.

You read each question and choose your answer. You can usually go back and change your answer before you submit the test. Once you submit, the computer scores it when ready and tells you whether you passed. If you passed, you walk out with a passing score sheet. If you did not pass, you can usually schedule a retest right there or online.

The test itself takes 20 to 40 minutes for most people. If you need extra time — because you read slowly, have a disability, or are taking the test in a language that is not your first language — ask the DMV staff when you check in. Most states allow extra time at no extra cost.

What happens if you do not pass

If you do not pass, you can take the test again. Most states let you retake it the same day or within a few days. There is usually no extra fee for a retest, though a few states charge a small fee. Before you retake the test, go back to your state's driver's manual and study the topics you got wrong. Many DMV offices will tell you which questions you missed so you know what to focus on.

Some states have a waiting period between attempts — for example, you might have to wait 24 hours before you can retake the test. Check your state's DMV website or ask the staff when you fail to find out the rules in your state. Most people pass on their second or third attempt if they study the manual between tries.

Differences between states

The number of questions, the passing score, the test format, and the topics emphasized all vary by state. Some states focus heavily on winter driving and snow; others focus on desert driving and heat. Some states ask many questions about pedestrian safety; others ask more about highway driving. Your state's driver's manual reflects these differences, so studying your state's manual is much more useful than studying a generic driving guide.

A few states offer the test in multiple formats — computer, paper, or even oral for people who cannot read. Most states offer the test only on a computer at a DMV office. Some states allow you to take the test at a third-party testing site, like a driving school, but this is less common. Check your state's DMV website to find out where and how you can take the test in your state.

Frequently Asked Questions

Can I take the DMV test online from home?

Most states do not offer the written test online. You must go to a DMV office or an approved testing site in person. A few states have experimented with remote testing, but this is not standard. Check your state's DMV website to see whether remote testing is available where you live.

How many times can I take the test if I keep failing?

Most states do not limit the number of times you can retake the test. You can keep trying until you pass. However, some states may require you to wait longer between attempts or take a driver education course if you fail multiple times. Your state's DMV website or a staff member at your local office can tell you the rules in your state.

Do I have to take the written test if I already have a license from another state?

Rules vary by state. Some states waive the written test if you transfer a license from another state. Others require you to take the test anyway. A few states offer a shortened version of the test for people transferring licenses. Contact your state's DMV to find out whether you need to take the test.

What if I fail the written test but pass the road test?

You cannot get your license if you fail the written test, even if you pass the road test. You must pass both tests. If you failed the written test, focus on studying and retaking it. Once you pass the written test, you can schedule your road test or take it if you have already passed it.

Is the DMV test the same as the permit test?

In most states, yes — the written test you take to get a learner's permit is the same test you take to get a full driver's license. Some states have a slightly different version for people renewing a license, but the permit test and the license test are usually identical. Check your state's DMV website to confirm.
