When you submit your application for your permit, you have ninety days or three attempts to successfully complete the written test. If you fail the test within ninety days you are allowed to retake it two more times, though usually you have to wait one day between attempts and you may be charged a reexamination fee each time. If you fail the test three times or wait longer than ninety days to retake it, then the application will be closed and you’ll have to repeat the process from the beginning.
In general, obtaining a learner’s permit is not a difficult process. Students who have studied the New Jersey Driver’s Handbook in its entirety rarely have any problem passing the test, and for extra assurance an excellent idea is take one or more of the free practice tests that are available online.
