The New Jersey Knowledge Test: Format and Content

The New Jersey knowledge test is a written exam you take at a DMV office to show you understand state traffic laws and safe driving practices. You answer 50 multiple-choice questions on a computer or paper form, and you need to get at least 40 questions correct to pass — that is 80 percent.

The test covers New Jersey traffic laws, road signs, right-of-way rules, parking regulations, and safe driving techniques. Questions come from the New Jersey Driver Manual, which the state publishes free online and in print at any DMV office. The test is offered in English and in several other languages, including Spanish, Portuguese, Korean, and Chinese.

You have up to one hour to complete the test. The computer version shows you one question at a time and lets you review and change your answers before you submit. If you take the paper version, you mark answers on a bubble sheet that gets scanned.

  • You do not need to schedule an appointment for the knowledge test at most New Jersey DMV offices, though wait times vary by location and time of day.

Who Takes the Knowledge Test and When

You take the knowledge test if you are getting your first New Jersey driver's license or if you are moving to New Jersey from another state and need to convert your out-of-state license. Drivers who already hold a valid New Jersey license do not retake the knowledge test when they renew.

If you are under 18, you must pass the knowledge test before you can get a Learner's Permit. Once you have the permit and have held it for at least six months, you can take the road test. If you are 18 or older, you can take both the knowledge test and the road test on the same day at the same DMV office, though you must pass the knowledge test first.

There is no time limit on how long you can hold a Learner's Permit, but you cannot drive alone — you must have a licensed driver at least 21 years old in the front seat with you at all times.

How to Prepare for the Test

The New Jersey Driver Manual is your main study resource. It covers every topic the test asks about. You can read it as a PDF from the New Jersey MVC (Motor Vehicle Commission) website, or you can pick up a printed copy at any DMV office. The manual is free either way.

Read through the entire manual at least once before you test. Pay special attention to sections on right-of-way, speed limits, parking rules, and what different road signs mean. The test asks many questions about these topics. Practice tests are available online through the MVC website — these are not official tests, but they follow the same format and cover the same material.

Some people study the manual in one or two sittings; others spread it over a few weeks. There is no minimum study time required, but most people who read the manual carefully and take a practice test or two pass on their first try.

What Happens on Test Day

Bring a valid form of ID — a passport, birth certificate, or state ID card all work. Bring proof of your Social Security number if you have one. 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. Bring proof of your New Jersey address, such as a utility bill or lease in your name.

Arrive at the DMV office early. Most offices do not require you to book an appointment for the knowledge test, but you may wait 30 minutes to two hours depending on the office and the time of day. Weekday mornings are usually less crowded than afternoons and weekends.

At the counter, tell the staff member you are here to take the knowledge test. They will check your documents, take your photo, and direct you to a testing station. You will sit at a computer or receive a paper test. Read each question carefully. You can skip a question and come back to it later on the computer version. When you finish, submit your test.

Passing, Failing, and Retesting

You get your score when ready after you submit the test. If you pass, the staff member will give you a printed score report. You can then move forward with getting your Learner's Permit or scheduling a road test, depending on your age and situation.

If you do not pass, you can retake the test the same day at most offices, though you may have to wait and pay the test fee again. Some offices limit retests to one per day; others allow multiple attempts. Call the DMV office ahead of time if you want to know their specific retesting policy.

There is no limit on how many times you can retake the knowledge test. Most people who fail study the manual again and pass on their second or third attempt. Take time to understand the questions you missed, not just memorize answers.

Test Fees and What Comes Next

The knowledge test fee is $10. You pay this fee each time you take the test, whether you pass or fail. This fee is separate from the Learner's Permit fee (which is $30) and the driver's license fee (which varies by age and license type).

After you pass the knowledge test, your next step depends on your age. If you are under 18, you get a Learner's Permit and must hold it for at least six months before you can take the road test. If you are 18 or older, you can take the road test at the same DMV office on the same day, or you can schedule it for another time.

The road test is a 20-minute drive with an examiner who watches how you handle the vehicle, follow traffic laws, and respond to road conditions. You must pass the knowledge test before you can take the road test, but you do not have to pass them on the same day.

Frequently Asked Questions

Can I use my phone or notes during the knowledge test?

No. You cannot bring study materials, phones, or any other devices into the testing area. The DMV staff will ask you to put your phone away before you sit down to test. Bringing unauthorized materials or attempting to cheat will result in your test being cancelled and may affect your ability to test again.

What if I do not speak English well?

The test is available in Spanish, Portuguese, Korean, and Chinese. Tell the DMV staff member which language you need when you arrive. If your language is not offered at that office, you may be able to test at a different location or on a different day when an interpreter is available. Call ahead to confirm.

Do I have to take the test on a computer, or can I take it on paper?

Most New Jersey DMV offices use computers for the knowledge test, but some still offer paper versions. Call the office where you plan to test and ask which format they use. Either way, the questions and passing score are the same.

What if I pass the knowledge test but then fail the road test?

Your knowledge test score stays valid. You do not have to retake the knowledge test. You can schedule another road test appointment and try again. There is no limit on how many times you can take the road test, though you must wait at least two weeks between attempts.

Can I take the knowledge test online from home?

No. The knowledge test must be taken in person at a New Jersey DMV office. You cannot take it remotely or by mail. You must show up with valid ID and proof of address.
