New Jersey's written test covers road signs, right-of-way rules, and safe driving practices

New Jersey's DMV written test, officially called the Knowledge Test, is a multiple-choice exam you take before you can get your learner's permit or driver's license. The test has 50 questions, and you need to answer at least 40 correctly to pass. You take it on a computer at a New Jersey Motor Vehicle Commission office, and you get your score when ready after you finish.

The test draws from the New Jersey Driver Manual, which covers traffic laws, road signs, parking rules, and how to handle different driving situations. You cannot bring notes, phones, or study materials into the testing room. If you fail, you can retake it the same day at most locations, though you may have to pay the test fee again.

  • You take the test on a computer at an MVC office, and results are available when ready.
  • If you fail, you can retake the test the same day at most locations, but you will pay the fee again.
  • You must bring a valid photo ID and proof of your Social Security number to the testing appointment.

What the test covers and how questions are formatted

Every question on the Knowledge Test is multiple choice with four answer options. Questions focus on three main areas: traffic signs and their meanings, right-of-way rules and traffic laws, and safe driving practices in different conditions.

Traffic sign questions show you a sign image and ask what it means or what you should do when you see it. Right-of-way questions describe a situation at an intersection or on a road and ask which driver has the right to go first. Safe driving questions ask how you should handle weather, pedestrians, bicycles, or emergency vehicles.

The test does not ask about your personal driving history or require you to know New Jersey-specific road names. It focuses on rules and situations that explore anywhere in the state. Questions are drawn from a larger pool, so two people taking the test on the same day may see different questions.

How to prepare using the New Jersey Driver Manual

The New Jersey Driver Manual is the official source for all test content. You can read it as a PDF from the New Jersey Motor Vehicle Commission website, or you can pick up a printed copy at any MVC office. The manual is organized by topic, so you can study one section at a time.

The manual includes sample questions at the end of each chapter. These are not the exact questions that will appear on your test, but they follow the same format and cover the same topics. Reading through the manual once and then reviewing the sample questions is a common study approach.

Some people use online practice tests created by third-party websites. These are not official, but many follow the structure and difficulty of the real test. If you use a practice test, make sure it is labeled as New Jersey material — tests from other states cover different laws and signs.

When you can take the test and how to schedule

You can take the Knowledge Test at any New Jersey Motor Vehicle Commission office. Most offices are open Monday through Friday during business hours, and some locations offer Saturday appointments. You do not need to schedule in advance at most offices — you can walk in and take the test the same day, though wait times vary by location and time of day.

A few MVC offices do require appointments for the written test. Check the Motor Vehicle Commission website or call your local office before you go to confirm whether you need to book ahead. If you do need an appointment, you can schedule one online through the MVC website.

The test fee is $10. You pay when you arrive at the office, before you take the test. If you fail and want to retake it the same day, you pay the fee again.

Documents you need to bring to the testing office

You must bring a valid photo ID to the test. Acceptable forms include a passport, military ID, or a state ID card. A school ID or work ID is not enough. If you do not have a photo ID yet, you can get a New Jersey state ID card at an MVC office before you take the written test.

You also need to bring proof of your Social Security number. This can be your Social Security card, a W-2 form, a tax return, or a birth certificate. If you do not have a Social Security number, bring a letter from the Social Security Administration stating that you are not may be able to access for one.

Bring your learner's permit if you already have one. If you are taking the test to get your first learner's permit, you do not need one yet — the test is the first step toward getting it.

What happens if you fail and how to retake the test

If you score below 40 out of 50, you fail the test. You will see your score on the computer screen before you leave the testing station. The office will give you a printed score report.

You can retake the test when ready at most locations — you do not have to wait days or weeks. You pay the $10 fee again and take a new test with a different set of questions. Some people pass on the second or third attempt after spending more time with the Driver Manual.

There is no official limit on how many times you can retake the test in New Jersey, but if you fail multiple times, an MVC employee may ask you questions about your study approach or suggest resources. If you are struggling, reading the manual chapter by chapter and taking practice tests on specific topics can help more than retaking the full test repeatedly.

Differences between the Knowledge Test and the road test

The Knowledge Test and the road test are two separate exams. You must pass the written test first to get your learner's permit. After you have held your learner's permit for a certain period and practiced driving, you schedule a road test with an MVC examiner.

The road test is a driving exam where an examiner sits in the car with you and watches you drive on real roads. The written test is a computer-based exam about rules and signs. Passing one does not mean you will pass the other — they measure different skills.

You cannot take the road test until you have your learner's permit, which requires passing the Knowledge Test. Some people pass the written test quickly but need more practice before they are ready for the road test.

Frequently Asked Questions

Can I use a translator or interpreter during the written test?

New Jersey offers the Knowledge Test in English and Spanish. If you need the test in Spanish, tell the MVC office when you arrive. If you need an interpreter for a language other than Spanish, contact your local MVC office in advance to request one — not all locations can provide interpreters for every language.

What happens if I run out of time before I finish all 50 questions?

There is no strict time limit for the Knowledge Test. You can take as long as you need to answer all 50 questions. Most people finish in 30 to 45 minutes. If you are taking a very long time, an MVC employee may check on you, but you will not be forced to stop.

Do I need to pass the written test before I can get my learner's permit?

Yes. Passing the Knowledge Test is the first step to getting your learner's permit in New Jersey. Once you pass, you can explore for the permit at the same MVC office, usually on the same day.

Can I retake the test if I passed but want a higher score?

New Jersey does not allow you to retake the test just to improve your score if you already passed. Once you pass with 40 or more correct answers, your learner's permit is issued based on that passing score. You cannot take the test again to try for a perfect score.

What if I need to take the test but I do not have a Social Security number?

Bring a letter from the Social Security Administration stating that you are not may be able to access for a Social Security number. The MVC office will accept this as proof. If you are not a U.S. citizen and do not have a Social Security number, contact your local MVC office to confirm what documents they will accept.
