What the New Jersey DMV written test covers and how to study for it
The New Jersey DMV written test is a 50-question multiple-choice exam that covers road signs, traffic laws, safe driving practices, and vehicle handling. You need a score of at least 40 correct answers (80 percent) to pass. The test is offered in multiple languages including English, Spanish, Portuguese, and others, and you can take it at any New Jersey Motor Vehicle Commission (MVC) office.
The test draws directly from the New Jersey Driver Manual, which the MVC publishes free online and in print. Every question on the exam comes from material in that manual, so studying it is the most direct way to prepare. You have 30 minutes to complete the test, and you can retake it the same day if you fail, though you must wait at least one day before a third attempt.
The MVC does not charge a fee to take the written test itself, though you will pay the standard license or permit fee when you pass and explore for your credential. If you fail, you can retake it when ready at no additional cost.

Where to find the official New Jersey Driver Manual
The New Jersey Driver Manual is the source document for every question on the written test. You can read it as a PDF from the official MVC website at nj.gov/mvc, or request a printed copy at any MVC office when you visit. The manual is updated periodically to reflect changes in traffic laws, so make sure you are using the current version.
The manual is organized by topic: road signs and their meanings, right-of-way rules, speed limits and safe following distance, parking regulations, driving under the influence, and vehicle maintenance basics. Each section includes diagrams of signs and illustrations of road situations. Reading through the entire manual once takes most people two to three hours, and many people find it helpful to read it twice — once to get familiar with the material and once to focus on areas they found confusing.
How to use practice tests effectively
The MVC does not publish an official practice test, but several third-party websites offer free practice tests based on the actual test format and content. These practice tests present 50 questions in the same multiple-choice format as the real exam and let you see which topics you need to study more. A practice test is most useful after you have read the driver manual at least once, because it shows you what you actually remember rather than what you think you remember.
When you take a practice test, treat it like the real exam: set a timer for 30 minutes, do not look at the manual while you are answering, and write down every question you get wrong. After you finish, go back to the driver manual and reread the section that covers each wrong answer. This cycle — read the manual, take a practice test, review your mistakes — is more effective than reading the manual multiple times or taking practice tests without reviewing them.
Some people take three or four practice tests in the days before their scheduled test date. If you are scoring 45 or higher on practice tests, you are likely ready for the real exam. If you are scoring below 40, spend more time with the driver manual before you test.
Common topics that appear frequently on the test
Certain topics show up on nearly every version of the New Jersey written test. Right-of-way rules — who goes first at a four-way stop, at a yield sign, when turning left across traffic — account for a significant portion of the test. Speed limits in residential areas (25 mph unless posted otherwise), school zones (20 mph when children are present), and the rules for passing on a two-lane road are tested regularly.
Road signs make up another large section. You need to know the shape and color of warning signs (yellow diamond), regulatory signs (white rectangle), and information signs (green rectangle), and you need to recognize specific signs like yield, no passing, pedestrian crossing, and merge. The test also includes questions about what to do if your brakes fail, how to handle a skid, the safe following distance at different speeds, and the legal blood alcohol content limit for drivers under 21 (zero tolerance).
Questions about parking — where you can and cannot park, what the different colored curbs mean — appear on most tests. You should also expect questions about seat belt laws, child safety seat requirements, and the rules for driving near emergency vehicles. Spend extra time on any of these topics if you find them confusing during your practice tests.
What to bring and expect on test day
Bring a valid form of identification to your MVC office on the day of your test. Acceptable forms include a passport, birth certificate, or a document from your school or employer with your name and date of birth. You do not need to bring the driver manual or any study materials — you will not be allowed to use them during the test.
Arrive at least 15 minutes before your scheduled appointment time. The MVC office will check your identification, confirm your information, and direct you to a testing station. The test is administered on a computer at most offices, though some locations still use paper tests. Either way, the format and content are identical. You will see one question at a time on the screen or paper, select your answer, and move to the next question. You cannot go back to change an earlier answer on most computer-based tests, so read each question carefully before you respond.
After you finish, the computer or staff member will tell you when ready whether you passed or failed. If you passed, you will pay your license or permit fee and have your photo taken. If you failed, you can schedule a retake for the same day or come back another time.
What to do if you fail and need to retake the test
If you do not pass on your first attempt, you can retake the test the same day at no additional charge. Many people find that taking a break, reviewing the questions they remember getting wrong, and then retesting works well. If you fail a second time, you must wait at least one day before a third attempt.
After a failed test, focus your study on the specific topics that gave you trouble. If you got multiple questions wrong about right-of-way, reread that section of the driver manual and take another practice test focused on those scenarios. If you struggled with road signs, spend time memorizing the shapes, colors, and meanings of the signs in the manual. Targeted study is more effective than rereading the entire manual again.
There is no limit to how many times you can retake the written test, and there is no waiting period between attempts after the first day. Some people pass on their second or third try after more focused study. Keep in mind that you must pass the written test before you can schedule a road test, so passing this exam is a necessary step toward getting your license.
Frequently Asked Questions
Can I use my phone or notes during the test?
No. You cannot bring study materials, phones, or notes into the testing area. The test is proctored, and using outside materials will result in an automatic failure and may affect your ability to retake the test. Arrive prepared to answer questions from memory.
What languages is the test offered in?
The test is offered in English, Spanish, Portuguese, Chinese, Korean, and several other languages. Tell the MVC office staff which language you need when you schedule your test or when you arrive. Not all locations offer every language, so call ahead to confirm availability at your office.
How long does the test take?
You have 30 minutes to complete the 50-question test. Most people finish in 15 to 25 minutes. You can leave early if you finish before the time is up, but you cannot extend your time if you run out.
Do I have to pass the written test before I take the road test?
Yes. You must pass the written test first, then schedule a separate appointment for the road test. The road test cannot be scheduled until you have a passing score on the written exam.
What is the passing score?
You must answer at least 40 out of 50 questions correctly, which is 80 percent. A score of 39 correct is a failing score, and you will need to retake the test.
