This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and New Jersey commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
General knowledge test
New Jersey publishes a 50-question General Knowledge test and requires at least 80 percent correct. Additional separate tests apply for the intended class, air-brake system, and endorsements. Passing General Knowledge alone does not authorize a combination, passenger, school-bus, tank, doubles/triples, or hazardous-material operation.
Test receipt and fee
The commercial examination test receipt costs $125 and is nonrefundable. The applicant identifies the planned CMV and endorsements so MVC can assign the correct tests. This test-receipt charge is separate from the four-year CDL credential, endorsement, TSA, fingerprint, transfer, duplicate, training, and vehicle costs.
Knowledge failure
After failing a New Jersey CDL knowledge test, the applicant must wait seven days before retesting. Retakes are not numerically capped, but MVC states that failure to pass within 180 days requires renewal of the test receipt. Paying again does not erase a required waiting period.
Languages
New Jersey CDL knowledge tests are available in English and Spanish; the HazMat endorsement test is English only. The broader language list published for ordinary driver testing does not apply to CDL modules. Interpreters and translated noncommercial tests cannot be assumed available for a CDL or HazMat test.
Practice blueprint boundary
Only the official 50-question General Knowledge size and 80 percent standard are treated as live New Jersey facts here. The application's endorsement module counts and four-choice format are internal practice settings because MVC does not publish a complete live module-by-module distribution and the app is not a replica of a secure test form.
Exam focus
Apply the rule to the exact New Jersey vehicle, credential, endorsement, age, commerce category, date, test stage, and operating facts. Current NJMVC instructions, controlling law, federal requirements, and the current official manual govern when an older form or brochure conflicts.
Commercial Driver License Exam Readiness: Achieving a passing grade of 80% or higher on state DMV commercial driver knowledge exams requires mastery of federal vehicle inspection procedures, gross vehicle weight ratings (GVWR / GCWR), braking mechanics, and road safety regulations.
