How to Get Your Wisconsin CDL License

The actual step-by-step process, from application to full license — not just what's on the exam. Confirm anything time-sensitive (fees, forms) with Wisconsin DMV directly.

  1. Hold a valid Wisconsin Class D driver's license

    You need a valid noncommercial Wisconsin Class D driver's license before applying, and must be at least 18 to drive commercially within Wisconsin, or 21 to cross state lines or transport hazardous materials, under federal rules that apply nationwide.

  2. Get your DOT medical certificate

    Complete a DOT medical examination and self-certify to the DMV that you're medically qualified to operate a commercial vehicle.

    • Medical Examiner's Certificate

  3. Pass the knowledge test(s)

    At a DMV office, pass the General Knowledge test, plus combination-vehicle and air-brake tests if applicable to your training vehicle.

    • Proof of eligibility

  4. Pay the fee and obtain your CLP

    Pay the $30 CLP fee, which covers Classes A, B, and C together, to receive your Commercial Learner's Permit, valid for 180 days.

  5. Hold the CLP at least 14 days

    Federal rule requires holding the CLP for a minimum of 14 days before scheduling the skills test.

  6. Complete entry-level driver training (ELDT)

    Since February 2022, federal rule requires theory and behind-the-wheel training through an FMCSA-registered provider before the skills test.

  7. Schedule and pass the skills test

    Book the skills test: a pre-trip inspection and an on-road driving evaluation for the CDL class you applied for.

  8. Receive your CDL

    Once you pass, the DMV issues your Class A, B, or C commercial driver's license, with any endorsements reflecting the additional tests you passed.

Notes

  • Commercial drivers are held to a 0.04% BAC threshold, half the standard 0.08% figure that applies to a regular passenger-vehicle driver.
  • A CDL holder who still holds an instruction permit or probationary license can't use a cell phone at all, handheld or hands-free, except to report an emergency.
  • Exact fees and required documents change over time — confirm the current process on the official Wisconsin DMV website before your appointment.
