Health requirement

DOT Medical Card / DOT Physical

Before the New Jersey Motor Vehicle Commission issues your CDL, you must pass a DOT physical — a medical exam performed by a certified examiner that confirms you're fit to operate a commercial vehicle.

The examiner checks your vision, hearing, blood pressure, and general health, then issues a Medical Examiner's Certificate (often called a "DOT medical card"). You file this with the New Jersey Motor Vehicle Commission, and it must be renewed periodically to keep your CDL valid.

  • Required for most CDL applicants before a permit or license is issued
  • Performed by an examiner listed on the FMCSA National Registry
  • Results in a Medical Examiner's Certificate (DOT medical card)
  • Must be kept current — typically renewed every 24 months or sooner

New Jersey CDL Permit Study Plan

A simple order to study in so you're ready for every test section on your permit exam.

  1. Start with the general knowledge test

    Every New Jersey CDL applicant takes this test. Study it first, then take full-length practice tests until you consistently score above 80%.

    Practice core tests
  2. Add the tests for your class

    Study Air Brakes if your vehicle has them, and Combination Vehicles if you're going for a Class A. Focus on one section at a time.

    See class tests
  3. Layer in your endorsements

    If your job needs hazmat, tanker, passenger, school bus, or doubles/triples, study those sections once your core tests feel solid.

    Browse endorsements
  4. Before test day

    Review missed questions before test day

    Retake practice tests, review every explanation for questions you miss, and only schedule your exam once you pass consistently.

Frequently Asked Questions

Common questions from CDL applicants in New Jersey.

Do I need Entry-Level Driver Training (ELDT) in New Jersey?

Yes. Effective February 7, 2022, New Jersey requires ELDT from an FMCSA-registered provider. Complete hazmat ELDT before the hazmat knowledge test. First-time Class A or B, upgrades, and first-time P, S, or H applicants must finish ELDT before the skills test.

Do I need a DOT medical certificate for a CDL in New Jersey?

Yes for non-excepted drivers (self-cert categories 1 or 3). Your Medical Examiner's Certificate must be electronic on the FMCSA National Registry. Excepted categories 2 or 4 without a passenger endorsement generally do not need an MEC. All passenger (P) endorsement holders need an electronic MEC regardless of commerce category.

What do I need to bring to apply for a CDL permit in New Jersey?

Make a CDL permit appointment and bring 6 Points of ID (including Social Security card, proof of address, and proof of legal presence), the CDL application, and the signed CDL Holder Self-Certification form. Pay the $125 non-refundable examination test receipt fee. Have your electronic MEC on the National Registry if required for your self-cert category.

Do I need a background check for a hazmat endorsement in New Jersey?

Yes. Complete hazmat ELDT before the hazmat knowledge test, pass the knowledge exam, and finish a TSA security threat assessment. Drivers under 21 cannot receive a hazmat endorsement. Endorsements cost $2 each when you get your CDL.

How long is a New Jersey CLP valid?

A New Jersey Commercial Learner's Permit is a digital credential (MVC no longer issues paper CLPs) valid for 180 days. Carry it with your New Jersey driver's license when operating a CMV. The $125 examination test receipt is also valid for 180 days and is non-refundable.

What are New Jersey CDL knowledge and skills retest rules?

Failed knowledge tests require a mandatory 7-day wait before retesting. There is no limit on knowledge attempts within the 180-day test-receipt period. If you fail the skills test, wait at least two weeks; repeated failures may require a six-month wait. Written, vision, and road scores remain valid for 360 days.

Who can get a non-domiciled CLP or CDL in New Jersey?

Under current federal rules, non-domiciled applicants generally need an unexpired I-94/94A showing H-2A, H-2B, or E-2 classification. Asylum seekers, asylees, refugees, and DACA recipients are not eligible, and Employment Authorization Documents alone are not accepted. U.S. citizens and lawful permanent residents follow the standard path.

Can military members waive New Jersey CDL skills testing?

Yes. Active, reserve, or recently discharged (within 12 months) service members with a valid New Jersey Class D license and qualifying military CMV experience may apply for the Military CDL Skills Waiver. Knowledge and vision tests are still required; you need a commanding-officer-certified waiver form, self-certification, and a Medical Examiner's Certificate.

Does PrepCDL cover New Jersey?

Yes. PrepCDL includes state-specific study guides and practice questions aligned with the New Jersey CDL manual, plus prep for every class and endorsement.
