The short answer
- Knowledge (written) test: if you fail, NJ MVC says you can re-test in 7 days (MVC, First Driver License). Make a new knowledge-test appointment.
- Road test: if you fail, you must wait at least 14 days before taking it again (MVC, Road Test).
- Your permit keeps running: MVC says that once you have your permit you have 2 years to finish the steps through your probationary license, or you must get a new permit. The fee table lists a GDL auto examination permit as valid for two years and a non-GDL one for 90 days.
- Score to pass: 40 of 50 questions (80%), per the NJ Driver Manual. For score details, see how many questions you can miss.
MVC builds the retest wait into its official first-license steps, so a failed attempt is a delay, not a restart. The useful part is what you do with the seven days.
If you failed the knowledge test
1. Rebook
MVC's first-license instructions list the steps in order: get your permit, then "Make an appointment for a Knowledge Test", bring your documents, and take the knowledge test plus a vision test. The same page says: "IF YOU FAIL, you can re-test in 7 days." Book the new appointment through MVC's appointment system and bring the same documents again.
2. Check your permit dates
The examination permit is what lets you test. MVC's License and Permit Fees table lists the auto examination permit at $10:
| Permit | Valid for | Fee |
|---|---|---|
| Examination Permit (auto), GDL | Two years | $10 |
| Examination Permit (auto), non-GDL | 90 days | $10 |
The fee table lists fees for permits; it does not list a separate fee for each knowledge-test retake. If you are close to the end of your permit's validity, ask MVC at your appointment whether you need a new permit.
3. Consider the language and interpreter options
The written test is offered in English, Arabic, Chinese (Mandarin), French, Spanish, Korean, Polish, Portuguese, Russian, Japanese, Hindi, Albanian and Turkish; oral tests are offered in English and Spanish (MVC, Knowledge Test). If you cannot read in any language, the Driver Manual says headphones are supplied for an oral test.
If your native language is not on the list, the Driver Manual says you must first attempt the test in an offered language. If you fail and feel you need an interpreter, tell MVC staff at the testing location; MVC arranges an interpreter in your native language and pays the fees. The manual asks you to tell MVC at least two weeks in advance of the date you intend to test, and MVC's Knowledge Test page says interpreter appointments are typically scheduled within four to six weeks. More detail: knowledge-test language options.
4. If the vision screening was the problem
A vision screening is required for all motorists. The Driver Manual's standard for a basic license is 20/50 vision with or without corrective lenses, and MVC may refer applicants with impaired vision to a physician. If that happens, follow MVC's instructions before you rebook.
Using the 7 days well
This is our suggestion, not an MVC requirement:
- Day 1: write down the topics that felt unfamiliar while they are fresh. Then take a full set of practice questions to see where you actually miss.
- Days 2–3: go back to the matching chapters of the NJ Driver Manual. Fines, distances, BAC limits and GDL hours are easy to mix up; drill the numbers to memorize.
- Days 4–5: review the topics other learners miss most in our mistake index and the most-missed questions. Signs and right-of-way are worth a second pass: traffic signs and parking, turns and right-of-way.
- Days 6–7: take full practice sets and aim well above the 40-of-50 line, so one unfamiliar question on test day does not decide the result.
Practice questions on this site are our own study questions. Practice scores help you find weak topics; they are not NJ MVC exam results and do not predict your official score.
If you failed the road test
MVC's Road Test page says: "You must wait at least fourteen (14) days before taking the road test again." The first-license page says the same. You still need your valid examination permit, your 6 Points of ID, a qualifying vehicle and an accompanying licensed driver for the retest.
Not every failed road test is about driving. MVC can deny a road test because of the vehicle: an unsafe vehicle, an improper or expired inspection sticker, equipment that blocks the examiner from the brakes, a self-parking vehicle, missing GDL decals for drivers under 21, or certain defects such as poor brakes or missing seatbelts. Check those before you go back. Our NJ road test guide walks through the requirements and skills tested.
How the waits fit together
| Situation | What MVC says | Source |
|---|---|---|
| Failed knowledge test | Re-test in 7 days | First Driver License |
| Failed road test | Wait at least 14 days | Road Test |
| Passed knowledge test, under 21 | Practice supervised driving at least 6 months before the road test | Road Test |
| Passed knowledge test, 21 or older | At least 3 months of supervised driving (GDL) | Road Test |
| Permit clock | 2 years to finish the steps through your probationary license, or get a new permit | First Driver License |
If you are new to New Jersey with a license from another country, the Driver Manual says out-of-country applicants must pass the knowledge test and vision screening and may be required to pass a road test, and that test results are valid for two years. See our license transfer guide.
