What the New Jersey Knowledge Test Covers and How It Works

The New Jersey knowledge test is a written exam you take at a Motor Vehicle Commission office to show you understand state traffic laws, road signs, and safe driving practices. You must pass this test before you can take the road test for a driver's license or motorcycle endorsement. The test is multiple choice, and you answer questions on a computer terminal at the MVC office — not online from home.

The test has 50 questions, and you need to answer at least 40 correctly to pass. Each question shows you four possible answers, and you select one. The test covers New Jersey traffic laws, right-of-way rules, parking regulations, what different road signs mean, and how to handle hazards. You have one hour to complete it.

You can take the test in English or Spanish. If English is not your first language, you may bring a translator to the testing room, though the translator cannot help you answer questions — they can only help you understand what the question is asking.

Key Takeaways

  • The knowledge test is 50 multiple-choice questions taken on a computer at an MVC office, and you must score at least 80 percent to pass.
  • You can retake the test the same day if you fail, but you must wait at least one day between attempts if you fail a second time.
  • The test covers New Jersey traffic laws, road signs, right-of-way rules, and safe driving practices from the New Jersey Driver Manual.
  • You do not need to schedule the test in advance at most MVC offices — you can walk in during business hours, though wait times vary by location and time of day.
  • Bring your learner's permit or valid ID, proof of residency, and your Social Security number or Individual Taxpayer Identification Number.

What Documents You Need to Bring

Bring your current New Jersey learner's permit. If you do not have one yet, you must get one before you can take the knowledge test. You will also need a valid form of ID — a passport, military ID, or out-of-state driver's license all work.

Bring proof that you live in New Jersey. A utility bill, lease, mortgage statement, or bank statement with your name and address dated within the last 30 days will work. A piece of mail from a government agency also counts.

Have your Social Security number or Individual Taxpayer Identification Number ready. You will need to provide it when you check in at the MVC office.

How to Study for the Test

The New Jersey Driver Manual is the official source for everything on the test. You can read it online at the MVC website or pick up a printed copy at any MVC office. The manual covers all the topics the test asks about: traffic laws, road signs, parking rules, right-of-way, and safe driving in different conditions.

Read through the entire manual at least once. Pay special attention to sections on right-of-way rules, speed limits, what to do at traffic lights and stop signs, and what different road signs mean. These topics appear frequently on the test.

The MVC website also offers a practice test with sample questions. Taking the practice test more than once helps you get used to the format and identify topics you need to review. The practice test is not identical to the real test, but it covers the same material and shows you how questions are worded.

Some people study for a few days; others study for a few weeks. How long you need depends on how familiar you already are with New Jersey traffic laws and how much time you can spend each day. Most people who read the manual and take the practice test two or three times pass on their first attempt.

Where to Take the Test and What to Expect

You take the test at a Motor Vehicle Commission office. New Jersey has MVC offices in most towns and cities. You can find the office nearest you and its hours on the MVC website.

Most offices do not require you to schedule the knowledge test in advance. You can walk in during business hours, check in at the front desk, and wait for your turn. Wait times vary — some offices have short waits in the morning, while others may have longer waits in the afternoon or on certain days of the week. The MVC website shows current wait times at each office.

When you check in, tell the staff member you want to take the knowledge test. They will verify your documents, collect your fee (currently $10), and direct you to a testing station. You will sit at a computer terminal, and the test will appear on the screen. You have one hour to answer all 50 questions. You can move back and forth between questions if you want to review your answers before you submit.

Once you submit your test, the computer scores it when ready and tells you whether you passed. If you pass, you will receive a notice that you can use to schedule your road test. If you fail, you can retake the test the same day at most offices, though you will pay the fee again.

What Happens If You Fail and Need to Retake It

If you do not pass on your first attempt, you can take the test again the same day at most MVC offices. You pay the fee again ($10), and you have another hour to answer the 50 questions. Many people pass on their second attempt after spending a few hours studying the topics they found difficult.

If you fail a second time, you must wait at least one day before you can take the test again. This waiting period gives you time to study more thoroughly. After you fail twice, some MVC offices may require you to wait longer or to show proof that you have studied before you can take the test a third time — call your local office to ask about their specific policy.

There is no limit to how many times you can retake the test, but each attempt costs $10. If you are failing repeatedly, spend more time with the Driver Manual and the practice test. Focus on the sections where you are missing the most questions.

Road Test may be able to access After You Pass

Once you pass the knowledge test, you receive a notice that you can use to schedule your road test. You do not have to schedule it when ready — you can take the road test weeks or months later if you need more time to practice driving.

To take the road test, you will need to bring your learner's permit, proof of insurance for the vehicle you will drive, and the vehicle itself. The vehicle must be registered, insured, and in safe working condition. You will drive with an MVC examiner for about 20 to 30 minutes on local roads. The examiner watches how you handle the vehicle, follow traffic laws, and respond to hazards.

You must have held your learner's permit for at least six months before you can take the road test, unless you are under 17 years old, in which case the requirement is different. Check the MVC website or call your local office to confirm the waiting period that applies to you.

Frequently Asked Questions

Can I take the knowledge test online from home?

No. The knowledge test must be taken in person at a Motor Vehicle Commission office on a computer terminal there. You cannot take it online or by mail.

Do I need to make an appointment for the knowledge test?

Most MVC offices do not require an appointment for the knowledge test. You can walk in during business hours. However, some offices may have changed their policy, so call ahead or check the MVC website for your local office.

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

If you do not submit your answers within one hour, the test automatically closes and scores what you have answered. Any questions you did not answer count as wrong. This is rare if you pace yourself — most people finish with time to spare.

Can I use a calculator or notes during the test?

No. You cannot bring any materials into the testing room except your ID and documents. You cannot use a phone, calculator, notes, or the Driver Manual during the test.

How long is the knowledge test score valid?

Your passing score is valid for one year. If you do not take and pass your road test within one year, you will need to retake the knowledge test before you can schedule the road test.
