Health requirement
DOT Medical Card / DOT Physical
Before the Wisconsin Department of Transportation 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 Wisconsin Department of Transportation, 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

Frequently Asked Questions
Common questions from CDL applicants in Wisconsin.
Do I need Entry-Level Driver Training (ELDT) in Wisconsin?
Yes for first-time CDL applicants, Class B to A upgrades, and first-time passenger, school bus, or hazmat endorsements. Finish ELDT before skills testing (or before the hazmat knowledge test). Drivers issued the same class or P/S/H before February 7, 2022, and certain military, farm, firefighter, and restriction-removal applicants are generally exempt.
Do I need a DOT medical certificate for a CDL in Wisconsin?
Yes when your tier of operation requires it. Complete form MV3230 and keep a valid Federal Medical Card on file. Effective April 13, 2025, exams are transmitted electronically from FMCSA to Wisconsin DMV within about 48 hours — paper, email, fax, and uploads are no longer accepted for exams on or after that date. Check Fed Med and tier status through DMV online services.
What do I need to bring to apply for a CDL permit in Wisconsin?
Bring a valid Wisconsin Class D license, complete forms MV3001 and MV3230, prove U.S. citizenship or legal status, and present your Federal Medical Card if required for your tier (or confirm electronic posting for exams on or after April 13, 2025). Knowledge tests are free walk-ins; use the online appointment scheduler if you want to pre-fill applications before visiting DMV.
Do I need a background check for a hazmat endorsement in Wisconsin?
Yes. Complete hazmat ELDT before the English-only hazmat knowledge test, file Hazardous Materials Endorsement Application MV3735, and get fingerprinted at a Wisconsin Fieldprint location within 7 days of passing (use code FPWIDMVHazmat). HME fees to DMV are about $67.25 ($57.25 with CDL renewal) plus about $23.75 to Fieldprint — both non-refundable.
How much do Wisconsin CDL permits and licenses cost?
A Commercial Learner Permit is $30 for 180 days. Knowledge tests are free. An original or 8-year renewal CDL is about $74. Third-party skills tests cost up to about $150 for a full test ($50 per segment). Hazmat endorsement fees to DMV are about $67.25 ($57.25 with renewal) plus about $23.75 for Fieldprint fingerprinting.
Does Wisconsin check the Drug and Alcohol Clearinghouse?
Yes. FMCSA requires Wisconsin DMV to downgrade any CDL or CLP holder with a Prohibited status in the Drug and Alcohol Clearinghouse. Privileges return when DACH shows Not Prohibited and no other issues remain.
Can military members waive the Wisconsin CDL skills test?
Possibly. Wisconsin residents who are current or former service members (within one year of separation) with a military license to operate CMV-equivalent vehicles may apply with form MV3588. Knowledge tests are still required. The waiver does not cover Hazardous Materials or School Bus endorsements.
Are farm vehicles exempt from a Wisconsin CDL?
Often yes for farmers, family members, and farm employees driving a farm-owned or leased CMV that is not for hire, within 150 miles of the farm, transporting farm supplies, produce, or machinery. Doubles/triples or vehicles designed to carry 16+ passengers still need a CDL with proper endorsements. Wisconsin also offers a restricted Farm Service (F) endorsement for certain B/C farm-service operations.
Does PrepCDL cover Wisconsin?
Yes. PrepCDL includes state-specific study guides and practice questions aligned with the Wisconsin CDL manual, plus prep for every class and endorsement.
