How do I prepare for the New Jersey CDL knowledge test?
If you are preparing for your first permit, start with general knowledge and the official New Jersey instructions below. If your vehicle needs air brakes or combination vehicles, add those federal study sets; for hazardous materials, use the separate hazmat set. Compare the state’s published test rules with its current manual before you test. These practice sets teach federal topics and do not copy the state exam.
This page is study material. It is not the New Jersey state exam, and it does not copy state test questions. Check the official New Jersey pages below before you test.
| Your situation | Start with… |
|---|---|
| A quick first try | Take a 10-question warm-up |
| Ready for a longer attempt | Take the 50-question general knowledge exam |
| Need state rules or documents | Check the New Jersey application steps |
New Jersey commercial driver manual (PDF) — link checked . Study its rules alongside our federal-standard bank. Our 50-question exam length is a study setting; use the official counts below for New Jersey.
New Jersey MVC’s CDL tests page checked November 10, 2026 prints a 50-question general knowledge test and an 80 percent passing score. The CDL FAQ also gives 80 percent as the passing grade. The testing pages and manual section checked do not print separate endorsement question counts. Our federal study sets do not reproduce MVC exam questions.

Federal study sets, not the New Jersey exam
Use general knowledge, air brakes, combination vehicles, and hazmat to study the federal topics. Finishing one of those sets does not mean you passed the New Jersey test.
