The DMV written test checks whether you know traffic laws, road signs, and safe driving rules for your state

The written test — sometimes called the knowledge test or permit test — is a multiple-choice exam you take at your DMV office before you can get a learner's permit or driver's license. You answer questions about traffic laws, right-of-way rules, parking, speed limits, and what different road signs mean. The test is not the same in every state: each state writes its own questions, sets its own passing score, and decides how many questions you see.

Most states give you between 30 and 50 questions and require you to answer 70 to 80 percent correctly to pass. You take the test on a computer at the DMV office, though a few states still use paper tests. If you fail, you can usually retake it the same day or within a few days, depending on your state's rules.

Key Takeaways

  • Each state writes its own test, so the questions and passing score differ by location — check your state DMV website to see the exact number of questions and required score.
  • Most tests cover traffic laws, road signs, right-of-way rules, and safe driving practices specific to your state's vehicle code.
  • You take the test on a computer at your DMV office, and results are usually available when ready after you finish.
  • If you fail, you can retake the test within days in most states, though some require you to wait a set number of days between attempts.
  • Study materials — usually the state driver's manual and practice tests — are free on your state DMV website.

What the test covers and how questions are worded

The test focuses on your state's traffic laws and what you need to know to drive safely and legally. Questions ask about speed limits in school zones, what to do at a red light with an arrow, how far back to park from a fire hydrant, and what a yellow diamond sign means. Some questions describe a driving scenario and ask what you should do; others show a road sign and ask what it means.

The exact topics vary by state because each state's vehicle code is different. For example, some states have specific rules about headlight use at dusk that others do not. Your state DMV website lists the topics covered and usually provides a study guide or driver's manual that shows you the exact rules you need to know.

Questions are written in plain language, though some readers find them tricky because they ask what you must do or what is not allowed, and you have to read carefully to pick the right answer. The test does not ask opinion questions or trick questions designed to confuse you — it asks whether you know the actual law.

How many questions and what score you need to pass

The number of questions and passing score depend on your state and whether you are taking the test for a learner's permit or a driver's license. Most states give 30 to 50 questions and require 70 to 80 percent correct to pass. A few states require 80 to 85 percent. Some states use different passing scores for different age groups — for example, a higher score for drivers under 18.

Your state DMV website will tell you the exact number of questions on your test and the passing score. Before you go to the DMV, look up this information so you know what to expect and what score you need to reach.

How to study and where to find practice materials

Your state DMV provides free study materials on its website, usually including the official driver's manual and practice tests. The driver's manual covers all the laws and rules the test will ask about. Practice tests let you see the types of questions you will face and check your knowledge before test day.

Read the manual section by section and take the practice test when you feel ready. If you score below the passing threshold on the practice test, go back to the manual and review the topics where you missed questions. Many people take the practice test several times until they consistently score above the passing score.

Some states offer the manual and practice test in multiple languages. If English is not your first language, check your state DMV website to see what languages are available.

What to bring and how the test works on the day

Bring a valid form of identification — usually a passport, birth certificate, or state ID — and proof of your Social Security number or tax ID. Bring any documents your state requires for your permit or license process, such as proof of residency or a completed process form. Check your state DMV website for the full list before you go.

When you arrive at the DMV, you will check in and wait to be called. A staff member will verify your identity and documents, then direct you to a computer terminal where you take the test. You will have a set amount of time — usually 30 to 60 minutes — to answer all the questions. You can go back and change your answers before you submit the test.

Once you submit, the computer scores your test when ready and tells you whether you passed or failed. If you pass, you move forward in the permit or license process. If you fail, the DMV staff will tell you when you can retake the test.

Retaking the test if you do not pass

If you fail, you can usually retake the test within a few days. Some states let you retake it the same day; others require you to wait one to seven days before your next attempt. A few states limit how many times you can retake the test in a certain period — for example, three times in 12 months. Check your state DMV website for the exact rules.

When you retake the test, you will see different questions, not the same ones you saw before. Study the topics where you missed questions on your first attempt. Many people pass on their second or third try after reviewing the material more carefully.

How the test differs by state and by permit type

Each state writes its own test, so the questions, passing score, and number of questions are different everywhere. Some states also have different tests for different types of permits — for example, a separate test for a motorcycle endorsement or a commercial driver's license. If you are seeking a special endorsement, your state DMV will tell you whether you need a separate written test and what it covers.

If you move to a new state, you may not have to retake the written test — many states accept valid licenses from other states. But if you are taking the test for the first time in your new state, you will take that state's test, not the one from where you moved.

Frequently Asked Questions

Can I use my phone or notes during the test?

No. The DMV does not allow phones, notes, or any study materials during the test. You must answer the questions from memory. If you are caught using a phone or other device, you will be asked to leave and may not be allowed to retake the test for a set period.

What happens if I run out of time before I finish all the questions?

Your test will be scored based on the questions you answered before time ran out. Unanswered questions count as wrong. If you do not finish, you will fail. This is rare if you study beforehand, because most people finish with time to spare.

Do I have to pass the written test before I can take the driving test?

Yes. You must pass the written test first to get your learner's permit, and you must have a valid permit before you can take the road test for your license. Some states require you to hold the permit for a set number of days or months before you can test for your license.

Is the test the same if I am over 18?

Usually yes, but some states have different passing scores or different rules for adult first-time drivers versus teenagers. Check your state DMV website to see whether age affects the test you take or the score you need.

What if I fail the test multiple times?

Most states let you retake the test as many times as you need, though some limit retakes to a certain number per year. If you keep failing, ask the DMV staff whether they offer in-person help or can point you to resources in your language. Some DMV offices have staff who can answer questions about specific topics you are struggling with.
